The search for superhumans has taken me to the very edge of the Earth. | 0:00:17 | 0:00:21 | |
I don't want to move a muscle in case I fall! | 0:00:21 | 0:00:24 | |
But imagine not only being able to stand here, | 0:00:24 | 0:00:27 | |
but being able to perform incredible feats of acrobatics up here! | 0:00:27 | 0:00:31 | |
To do that would take nerves of steel or the powers of a superhero. | 0:00:31 | 0:00:36 | |
A superhero like Spider-Man, with amazing balance and agility, | 0:00:36 | 0:00:40 | |
or like a real-life Daredevil, with absolutely no fear! | 0:00:40 | 0:00:44 | |
But I've heard of a REAL man with super-agility - | 0:00:44 | 0:00:47 | |
a man who can balance on anything. | 0:00:47 | 0:00:50 | |
A man with no fear. | 0:00:50 | 0:00:52 | |
Eskil Ronningsbakken discovered he had incredible balancing skills | 0:00:53 | 0:00:57 | |
when he was a child in Norway and, at 18, he joined the circus. | 0:00:57 | 0:01:01 | |
Over ten years later, Eskil lives life on the edge, | 0:01:01 | 0:01:04 | |
performing death-defying stunts all over the world, | 0:01:04 | 0:01:07 | |
without any safety harnesses. | 0:01:07 | 0:01:10 | |
Tim's travelled to the USA to meet up with Eskil. | 0:01:10 | 0:01:13 | |
And here he is! Eskil, it's fantastic to meet you, it really is! | 0:01:15 | 0:01:19 | |
-Nice to meet you. -Is it true what they say - | 0:01:19 | 0:01:22 | |
-can you balance on absolutely anything? -ALMOST anything. | 0:01:22 | 0:01:25 | |
There's nothing I know about that I couldn't balance on. | 0:01:25 | 0:01:28 | |
Standing on the edge of anything is really, really scary. | 0:01:28 | 0:01:31 | |
-Is it still scary to you? -Yes, it's still a little bit scary - | 0:01:31 | 0:01:34 | |
that's natural to any human being, to feel a little bit of fear. | 0:01:34 | 0:01:38 | |
But what I learn is to control this fear. | 0:01:38 | 0:01:41 | |
What we would like to do is to put you through three Super-Tests | 0:01:41 | 0:01:44 | |
to try and work out what it is that makes you so unique. | 0:01:44 | 0:01:47 | |
In order to do this, we're going to have to find someone | 0:01:47 | 0:01:50 | |
to perform with you. A man to try and match you. | 0:01:50 | 0:01:53 | |
A man who will probably not do that well. | 0:01:53 | 0:01:56 | |
Eskil, it's me. Are you up for that? | 0:01:56 | 0:01:58 | |
-Oh, yeah. Welcome aboard. -OK! | 0:01:58 | 0:02:00 | |
This is Dr Megan John. She's an expedition doctor | 0:02:00 | 0:02:04 | |
and has kept people alive in some of the most dangerous environments. | 0:02:04 | 0:02:08 | |
She's devised three Super-Tests to discover how Tim and Eskil's bodies | 0:02:08 | 0:02:12 | |
react differently when balancing. | 0:02:12 | 0:02:14 | |
For Super-Test One, we're off to Hollywood, Los Angeles. | 0:02:16 | 0:02:20 | |
Hollywood is famous for big film stars | 0:02:20 | 0:02:23 | |
and even bigger film studios. | 0:02:23 | 0:02:25 | |
What do you think? This is a real Hollywood film studio! | 0:02:27 | 0:02:30 | |
This is massive, this is huge! | 0:02:30 | 0:02:32 | |
This is about the size of a full-size football pitch - | 0:02:32 | 0:02:34 | |
this is enormous! | 0:02:34 | 0:02:36 | |
And, Tim, not only is it big, | 0:02:36 | 0:02:37 | |
you'll notice it's quite high, the ceilings, too. | 0:02:37 | 0:02:40 | |
Yeah, REALLY high. | 0:02:40 | 0:02:41 | |
Well, Tim, it's 11.5 metres high, to be exact, | 0:02:41 | 0:02:44 | |
which is almost the same height as three double-decker buses. | 0:02:44 | 0:02:47 | |
The studio needs to be high because, for this test, | 0:02:47 | 0:02:50 | |
Dr Megan is getting Tim and Eskil to attempt a crate climb. | 0:02:50 | 0:02:54 | |
They will have to balance on top of milk crates | 0:02:54 | 0:02:56 | |
as they stack them higher and higher. | 0:02:56 | 0:02:59 | |
As the stack gets higher, the task gets harder, | 0:02:59 | 0:03:02 | |
so Dr Megan is testing who's got the best balance | 0:03:02 | 0:03:04 | |
and can climb the highest. | 0:03:04 | 0:03:06 | |
As usual, she'll be recording what's happening to their bodies. | 0:03:06 | 0:03:09 | |
Firstly, I'm going to be fitting these bands around your heads, | 0:03:11 | 0:03:15 | |
which will record your brainwaves. | 0:03:15 | 0:03:17 | |
And I'm going to put an accelerometer on you both, | 0:03:17 | 0:03:19 | |
just between your shoulder blades. | 0:03:19 | 0:03:22 | |
Now, essentially this piece of equipment measures | 0:03:22 | 0:03:24 | |
how much wobble you're doing. | 0:03:24 | 0:03:26 | |
Balancing on anything is extremely dangerous - | 0:03:26 | 0:03:29 | |
you should never attempt to try anything like this | 0:03:29 | 0:03:31 | |
without specialist equipment and experts present. | 0:03:31 | 0:03:34 | |
Dr Megan has asked experienced climbing experts | 0:03:34 | 0:03:38 | |
to help set up this test and to be on standby all the way through. | 0:03:38 | 0:03:42 | |
They're attaching Tim and Eskil to safety ropes. | 0:03:42 | 0:03:45 | |
These ropes will not hold them up or help them stay balanced, | 0:03:45 | 0:03:48 | |
but they will catch them when they eventually fall off the crates. | 0:03:48 | 0:03:51 | |
-Are you both ready to go? -Yeah. -Yes. | 0:03:51 | 0:03:54 | |
Right, then, Tim, you're up first. | 0:03:54 | 0:03:56 | |
The higher the crates get, the more wobbly they become, | 0:03:56 | 0:04:00 | |
and your body automatically moves to try and stay balanced. | 0:04:00 | 0:04:04 | |
As you get higher, you might get scared, panic and make mistakes. | 0:04:04 | 0:04:08 | |
If you get really scared, your muscles could start to shake, | 0:04:08 | 0:04:12 | |
making it even harder to balance. | 0:04:12 | 0:04:14 | |
Eventually the tower will become so high and unstable, | 0:04:14 | 0:04:17 | |
it will topple over and you'll fall off. | 0:04:17 | 0:04:20 | |
Without a safety harness, you would seriously injure yourself, | 0:04:20 | 0:04:23 | |
or even die. | 0:04:23 | 0:04:24 | |
OK, I'm going to go. Doing this... Standing on that one. | 0:04:24 | 0:04:29 | |
There we go. | 0:04:31 | 0:04:33 | |
OK. And I mustn't stand like this, obviously, | 0:04:33 | 0:04:36 | |
cos when I get higher, they could go like that. | 0:04:36 | 0:04:39 | |
-That would be bad, wouldn't it? -That would be bad. | 0:04:39 | 0:04:41 | |
OK. So if I stand on one crate like this, and do that... | 0:04:41 | 0:04:45 | |
Let's try the next one. Thank you. | 0:04:46 | 0:04:48 | |
OK, that was quite wobbly getting up on that one. | 0:04:51 | 0:04:53 | |
-I've got to watch that. -Even at these relatively low number of crates, | 0:04:53 | 0:04:57 | |
every time he adds one in, he starts to wobble more. | 0:04:57 | 0:05:00 | |
What's happening to Tim | 0:05:00 | 0:05:02 | |
is all to do with what's going on inside his ears. | 0:05:02 | 0:05:05 | |
Your inner ears send signals to your brain to tell it you are moving. | 0:05:07 | 0:05:11 | |
Deep inside your ear there are three little loops filled with liquid. | 0:05:11 | 0:05:14 | |
In the liquid there are lots of tiny hairs | 0:05:14 | 0:05:17 | |
which sway back and forth, like weeds in a river. | 0:05:17 | 0:05:19 | |
When you move, the liquid in your ear moves, | 0:05:19 | 0:05:21 | |
making the tiny hairs move too. | 0:05:21 | 0:05:23 | |
These moving hairs tell your brain that you're moving. | 0:05:23 | 0:05:26 | |
Your brain can then quickly tell your muscles | 0:05:26 | 0:05:28 | |
to shift you in the opposite direction to keep you balanced. | 0:05:28 | 0:05:31 | |
There it goes. | 0:05:35 | 0:05:36 | |
Every time he steps up, he has to look down to the ground | 0:05:36 | 0:05:39 | |
to pick the crate up, and that causes an adrenaline surge | 0:05:39 | 0:05:42 | |
and his legs start to shake. | 0:05:42 | 0:05:43 | |
Just watch his leg as he climbs up onto this next level. | 0:05:43 | 0:05:46 | |
OK... Ooh! | 0:05:48 | 0:05:51 | |
I'm shaking a lot. | 0:05:51 | 0:05:52 | |
It feels harder when you're this high up. | 0:05:52 | 0:05:55 | |
It must be my brain going, "It's really hard, it's really scary!" | 0:05:55 | 0:05:58 | |
There we go. | 0:05:58 | 0:05:59 | |
There's a little peak there, | 0:05:59 | 0:06:02 | |
as he's started to wobble more and more. | 0:06:02 | 0:06:05 | |
It's just constantly moving now. | 0:06:05 | 0:06:08 | |
Wow, it really has got more wobbly, | 0:06:08 | 0:06:11 | |
and I'm having to focus really hard. | 0:06:11 | 0:06:13 | |
I feel my brain is telling my legs to do a lot of this with my feet. | 0:06:13 | 0:06:17 | |
Tim is doing this | 0:06:17 | 0:06:19 | |
because, to stay balanced, you need to keep your weight over your feet, | 0:06:19 | 0:06:22 | |
and your brain will move bits of your body to keep you balanced. | 0:06:22 | 0:06:26 | |
In all your muscles, you have sensing cells called proprioceptors | 0:06:26 | 0:06:30 | |
that send a signal to your brain so it can work out | 0:06:30 | 0:06:33 | |
where your body bits are, even if you're not looking at them. | 0:06:33 | 0:06:36 | |
Every time your muscles move, these proprioceptors move too, | 0:06:36 | 0:06:40 | |
so your brain can keep a track of where every bit of your body is | 0:06:40 | 0:06:43 | |
and move bits of it to keep you balanced. | 0:06:43 | 0:06:45 | |
After 16 minutes, Tim is now on box ten and is very wobbly. | 0:06:46 | 0:06:52 | |
I can just feel that the crates are going to go away from me. | 0:06:52 | 0:06:56 | |
Whoa... Whoa! Wow! | 0:06:56 | 0:06:57 | |
I've never thought I was going to go THAT way before. | 0:06:57 | 0:07:00 | |
I thought I was going to go forward off the top of these. | 0:07:00 | 0:07:03 | |
Wow, my balance is all over the place. Whoa... Whoa, whoa, whoa. | 0:07:03 | 0:07:07 | |
Let's just right ourselves here. Come on. | 0:07:07 | 0:07:10 | |
Oh! Here we go, I'm on ten. I'm on ten. | 0:07:10 | 0:07:13 | |
From the accelerometer, I can see that Tim really struggled | 0:07:13 | 0:07:16 | |
to keep his body still. | 0:07:16 | 0:07:18 | |
There's a lot of variation in the graph here. | 0:07:18 | 0:07:22 | |
It's crate number 11 for Tim, | 0:07:22 | 0:07:24 | |
and he's really starting to look unsteady now. | 0:07:24 | 0:07:27 | |
This is not a good scenario. Uh-oh. | 0:07:27 | 0:07:30 | |
The whole block is actually moving there. | 0:07:30 | 0:07:32 | |
Oh, my word, I've separated the columns now. | 0:07:32 | 0:07:36 | |
I've separated the columns out. | 0:07:36 | 0:07:38 | |
I don't know how long this is going to last, Megan. | 0:07:38 | 0:07:41 | |
I've got to be honest, Doctor. | 0:07:41 | 0:07:43 | |
OK, nice and calm, nice and calm, nice and calm... | 0:07:43 | 0:07:46 | |
Talking to themselves is one of the things people do | 0:07:46 | 0:07:49 | |
to calm themselves down when they're nervous. | 0:07:49 | 0:07:51 | |
And Tim is doing it a lot. | 0:07:51 | 0:07:54 | |
-Oooh! -Oh! | 0:07:54 | 0:07:56 | |
Wow, that took the most supreme effort of balance | 0:07:56 | 0:07:59 | |
I think I've ever managed in the history of my life. | 0:07:59 | 0:08:02 | |
Oh, I don't like this at all. | 0:08:02 | 0:08:05 | |
This is so wobbly. | 0:08:05 | 0:08:07 | |
But I'm not sure how long this is going to last, Megan. | 0:08:07 | 0:08:10 | |
OK. | 0:08:12 | 0:08:13 | |
Uh-oh. | 0:08:14 | 0:08:15 | |
One... | 0:08:15 | 0:08:18 | |
two... | 0:08:18 | 0:08:20 | |
three... | 0:08:20 | 0:08:21 | |
Whoa! And at last, Tim has fallen! | 0:08:24 | 0:08:28 | |
I've gone! It's not gone well. | 0:08:28 | 0:08:31 | |
Actually, it's gone better than Tim thinks. | 0:08:31 | 0:08:34 | |
It took 45 minutes to get there, but Tim managed to balance | 0:08:34 | 0:08:37 | |
on an impressive 12 crates, which is 3 metres 66cm high. | 0:08:37 | 0:08:42 | |
That's taller than the top of a fire engine, | 0:08:42 | 0:08:44 | |
which is a really good result. | 0:08:44 | 0:08:47 | |
But let's see how Eskil does. | 0:08:47 | 0:08:49 | |
Let's do it. | 0:08:49 | 0:08:50 | |
Was two.... | 0:08:59 | 0:09:01 | |
Eskil is already working much faster than Tim | 0:09:01 | 0:09:04 | |
to start building his crate tower. | 0:09:04 | 0:09:06 | |
He's making these first few crates look easy. | 0:09:06 | 0:09:10 | |
And then number five... | 0:09:10 | 0:09:12 | |
The point of balance for the body is through the middle - | 0:09:12 | 0:09:15 | |
through the tummy button. | 0:09:15 | 0:09:17 | |
Every time Eskil does a vulnerable move - | 0:09:17 | 0:09:19 | |
putting another crate on top of the pile - | 0:09:19 | 0:09:22 | |
he does so crouched down | 0:09:22 | 0:09:25 | |
to try to reduce the amount of wobble. | 0:09:25 | 0:09:28 | |
Another one, please. | 0:09:28 | 0:09:30 | |
He's controlling his breathing, controlling his movements. | 0:09:30 | 0:09:33 | |
Everything is considered, is thought about. | 0:09:33 | 0:09:36 | |
Crate number seven is more than halfway | 0:09:38 | 0:09:41 | |
to the height of Tim's crate tower. | 0:09:41 | 0:09:43 | |
Eskil is speeding towards Tim's total of 12 crates. | 0:09:43 | 0:09:46 | |
It's just taken him | 0:09:46 | 0:09:48 | |
a lot less time to get used to each new step that he takes. | 0:09:48 | 0:09:52 | |
Eskil doesn't seem to have that fear factor. | 0:09:53 | 0:09:57 | |
He's completely in control of his movements. | 0:09:57 | 0:10:00 | |
See how he's using his breathing and his arms to stabilise himself. | 0:10:00 | 0:10:04 | |
But actually, the central part of his body is barely moving at all, | 0:10:04 | 0:10:08 | |
from the data I'm getting from the accelerometer. | 0:10:08 | 0:10:11 | |
So that's number ten, Eskil. | 0:10:12 | 0:10:15 | |
Ten crates in, and only now | 0:10:15 | 0:10:16 | |
does Eskil's tower show the first signs of wobble. | 0:10:16 | 0:10:20 | |
You're doing really well. | 0:10:20 | 0:10:21 | |
Eskil is now on crate 11. | 0:10:25 | 0:10:28 | |
Moving from crate 11 to 12 | 0:10:29 | 0:10:31 | |
is the height that Tim lost his balance and fell. | 0:10:31 | 0:10:34 | |
But Eskil's still able to balance on the crates. | 0:10:41 | 0:10:44 | |
With Eskil, it's not about mind over matter. | 0:10:46 | 0:10:49 | |
It's not that he's frightened of this. | 0:10:49 | 0:10:51 | |
It's just the sheer challenge, physically, | 0:10:51 | 0:10:54 | |
of standing on top of a load of crates. | 0:10:54 | 0:10:57 | |
After only 19 minutes, Eskil is already on crate 15, | 0:10:57 | 0:11:01 | |
three crates higher than Tim managed. | 0:11:01 | 0:11:04 | |
He may be making this look easy, | 0:11:04 | 0:11:05 | |
but his body is working really hard to keep him balanced. | 0:11:05 | 0:11:08 | |
Eskil is now over five metres in the air, | 0:11:10 | 0:11:12 | |
plus his own two-metre height. | 0:11:12 | 0:11:14 | |
And with each new box, he's adding another 30.5cm to that height, | 0:11:14 | 0:11:19 | |
making the tower more and more precarious. | 0:11:19 | 0:11:22 | |
Amazingly, Eskil is now onto his 18th crate. | 0:11:27 | 0:11:31 | |
This is six crates more and almost two metres higher than Tim climbed. | 0:11:31 | 0:11:35 | |
And he's still standing and happy to attempt crate number 19. | 0:11:47 | 0:11:51 | |
Remarkably, the tower is now almost 5 metres 80cm high, | 0:11:55 | 0:11:59 | |
and it's become incredibly unstable. | 0:11:59 | 0:12:02 | |
HE GRUNTS | 0:12:04 | 0:12:05 | |
Wow! WOW! | 0:12:11 | 0:12:13 | |
Eskil managed to stay balanced at over two metres higher then Tim. | 0:12:16 | 0:12:19 | |
He got to an amazing 5.8 metres, | 0:12:19 | 0:12:22 | |
which is around the height of an average giraffe. | 0:12:22 | 0:12:25 | |
As Tim's results show, most people lose their balance | 0:12:25 | 0:12:27 | |
much quicker than Eskil, so what makes him able to do it? | 0:12:27 | 0:12:31 | |
When you're balancing, you need to keep your weight over your feet. | 0:12:33 | 0:12:37 | |
If you start to tip to one side, your brain signals to your muscles | 0:12:37 | 0:12:41 | |
to move the other way, to stop you falling. | 0:12:41 | 0:12:43 | |
But if you're balancing on something unusual, | 0:12:43 | 0:12:45 | |
you're likely to move too far and lose your balance. | 0:12:45 | 0:12:49 | |
Because Eskil has been practising | 0:12:49 | 0:12:50 | |
balancing on unusual things for over 20 years, | 0:12:50 | 0:12:53 | |
his brain has learned to tell his body | 0:12:53 | 0:12:55 | |
to do tiny movements, so he doesn't move too much and lose his balance. | 0:12:55 | 0:12:59 | |
'Tough test! But there are places | 0:13:01 | 0:13:03 | |
'where incredible balance is vital to survive.' | 0:13:03 | 0:13:06 | |
The Korowai tribe live in the Indonesian rainforest. | 0:13:07 | 0:13:10 | |
Balancing is second nature to them | 0:13:10 | 0:13:12 | |
because they live in tree houses over 35 metres above the ground, | 0:13:12 | 0:13:17 | |
taking everything they need up tall bamboo ladders. | 0:13:17 | 0:13:20 | |
If they fell, they would die. | 0:13:22 | 0:13:24 | |
But even the youngest children move with ease amongst the branches | 0:13:24 | 0:13:27 | |
without using ropes or harnesses. | 0:13:27 | 0:13:30 | |
Up high, they escape jungle floods, biting insects and attackers. | 0:13:30 | 0:13:35 | |
For the Korowai, | 0:13:35 | 0:13:36 | |
the higher your tree house, the more you are respected. | 0:13:36 | 0:13:39 | |
For this test, Dr Megan has taken Tim and Eskil | 0:13:43 | 0:13:46 | |
to the Aquatics Center in Pasadena, LA. | 0:13:46 | 0:13:49 | |
Take a look up there. That's a ten-metre-high diving board. | 0:13:50 | 0:13:54 | |
I think that one of the most important things about being able | 0:13:54 | 0:13:57 | |
to balance well is to overcome your body's natural fear of heights. | 0:13:57 | 0:14:01 | |
So to really up the fear factor for today's test, | 0:14:01 | 0:14:04 | |
you're going to be doing it without harnesses. | 0:14:04 | 0:14:07 | |
No harness! You're going to feel free today. | 0:14:07 | 0:14:09 | |
It's really high, Eskil. That's much higher than we were yesterday. | 0:14:09 | 0:14:13 | |
I really don't like heights. | 0:14:13 | 0:14:15 | |
-But you've got water underneath. -I REALLY don't like heights. | 0:14:15 | 0:14:18 | |
To test Tim and Eskil's fear levels, | 0:14:19 | 0:14:21 | |
Dr Megan will be asking them to perform a number of moves | 0:14:21 | 0:14:24 | |
on the edge of this ten-metre-high diving board. | 0:14:24 | 0:14:28 | |
Move one is to stand on the edge looking out. | 0:14:28 | 0:14:31 | |
Move two is to stand on one leg. | 0:14:31 | 0:14:34 | |
Move three is to stand with their backs to the water | 0:14:34 | 0:14:36 | |
and their heels over the edge of the board. | 0:14:36 | 0:14:39 | |
Move four is to do a handstand right on the edge of the diving board. | 0:14:39 | 0:14:43 | |
I'll be fitting you both with heart-rate monitors. | 0:14:45 | 0:14:48 | |
We know that the more frightened you get, the faster your heart goes. | 0:14:48 | 0:14:51 | |
And I'll be fitting you with GSRs. | 0:14:51 | 0:14:53 | |
They'll show me how sweaty you're getting. | 0:14:53 | 0:14:56 | |
Guys, let's get you kitted up. | 0:14:56 | 0:14:58 | |
Diving boards can be really dangerous | 0:14:58 | 0:15:00 | |
and trying moves like this at such a height could kill you. | 0:15:00 | 0:15:03 | |
Dr Megan has safety lifeguards on stand-by, and Tim and Eskil | 0:15:03 | 0:15:07 | |
have been briefed about the best way to hit the water if they fall. | 0:15:07 | 0:15:10 | |
No-one should ever try anything like this. | 0:15:10 | 0:15:13 | |
Tim, if you can make your way up to the ten-metre board... | 0:15:15 | 0:15:17 | |
OK, I'm coming up. | 0:15:17 | 0:15:19 | |
An average human will feel fear | 0:15:21 | 0:15:24 | |
standing on the edge of something ten metres high | 0:15:24 | 0:15:26 | |
and your brain sends out an alarm to your body, | 0:15:26 | 0:15:29 | |
telling you to get down quickly. | 0:15:29 | 0:15:31 | |
If you don't, your heart starts to race, | 0:15:31 | 0:15:34 | |
your pupils open wider | 0:15:34 | 0:15:36 | |
and your hairs stand on end. | 0:15:36 | 0:15:37 | |
You start sweating. | 0:15:37 | 0:15:39 | |
Eventually, you will begin to panic and become confused. | 0:15:39 | 0:15:42 | |
If you get really scared, you could have a panic attack | 0:15:42 | 0:15:45 | |
and you might pass out and fall off the edge. | 0:15:45 | 0:15:48 | |
Falling from this height | 0:15:48 | 0:15:49 | |
would cause serious injury | 0:15:49 | 0:15:50 | |
and possibly even death. | 0:15:50 | 0:15:53 | |
-How you doing, Tim? -I don't like this. | 0:15:54 | 0:15:56 | |
If at any point you really feel like you can't go on, that's fine. | 0:15:56 | 0:16:00 | |
-OK. -So if you make your way towards the edge of the board | 0:16:00 | 0:16:03 | |
-and just stand still at the edge for ten seconds. -OK. | 0:16:03 | 0:16:07 | |
I don't like this. | 0:16:07 | 0:16:08 | |
OK. | 0:16:10 | 0:16:11 | |
Tim is terrified of heights | 0:16:11 | 0:16:14 | |
and just standing on the top of the diving board | 0:16:14 | 0:16:16 | |
makes him feel scared - so walking to the edge is a real challenge. | 0:16:16 | 0:16:20 | |
So you can see if you look closely, his legs are already shaking. | 0:16:20 | 0:16:24 | |
He's struggling to stay balanced, even at this position. | 0:16:24 | 0:16:27 | |
His heart rate... | 0:16:27 | 0:16:28 | |
144 beats a minute. | 0:16:28 | 0:16:31 | |
That's over 50 beats a minute extra than what he was doing at rest. | 0:16:31 | 0:16:36 | |
OK, Tim. You did really well in that first position. | 0:16:36 | 0:16:38 | |
If you could step back for me... | 0:16:38 | 0:16:40 | |
-Whoa, WHOA! -How did that feel? | 0:16:40 | 0:16:43 | |
Yeah, I'm not happy in this environment. | 0:16:43 | 0:16:45 | |
This is not a good environment for me. | 0:16:45 | 0:16:47 | |
Tim found standing at the edge of the diving board so scary | 0:16:48 | 0:16:51 | |
that Dr Megan is concerned that he won't cope with | 0:16:51 | 0:16:54 | |
the next stage of the challenge - balancing on one leg. | 0:16:54 | 0:16:59 | |
It's going to be much harder to balance. | 0:16:59 | 0:17:00 | |
You're already a bit shaky, even here, | 0:17:00 | 0:17:02 | |
so I think it's probably sensible | 0:17:02 | 0:17:03 | |
if you take off this extremely expensive GSR kit. | 0:17:03 | 0:17:06 | |
Do you think that? Did you get my sweat readings? | 0:17:06 | 0:17:09 | |
-We have so far. -OK. | 0:17:09 | 0:17:11 | |
Tim is sweating because he's scared. | 0:17:11 | 0:17:14 | |
And this is because when your brain thinks you're in danger, | 0:17:14 | 0:17:17 | |
it immediately starts sending signals | 0:17:17 | 0:17:20 | |
to adrenal glands near your kidneys. | 0:17:20 | 0:17:22 | |
These glands release a hormone called adrenalin into your blood, | 0:17:22 | 0:17:25 | |
which makes your lungs work harder so you breathe more oxygen. | 0:17:25 | 0:17:29 | |
Your heart beats faster to get more blood to your muscles | 0:17:29 | 0:17:32 | |
and two million sweat glands on your skin start sweating | 0:17:32 | 0:17:35 | |
to help you stay cool. | 0:17:35 | 0:17:37 | |
You react like this because when you're scared, | 0:17:37 | 0:17:39 | |
your body gets ready to run away fast from danger. | 0:17:39 | 0:17:42 | |
But will Tim be able to face his fear? | 0:17:42 | 0:17:45 | |
When you feel comfortable, if you can stand on one leg | 0:17:45 | 0:17:48 | |
and hold it for ten seconds, OK? | 0:17:48 | 0:17:50 | |
It's just not a job for a man with a chronic fear of heights! | 0:17:50 | 0:17:54 | |
This is real mind-over-matter stuff for Tim. | 0:17:54 | 0:17:57 | |
Every part of his body is telling him he's in danger | 0:17:57 | 0:18:00 | |
and he should run away, not balance at the edge on one leg! | 0:18:00 | 0:18:03 | |
With a ten-metre drop in front of him, Tim is working really hard | 0:18:05 | 0:18:08 | |
to overcome his fear, but can he complete the Super-Test? | 0:18:08 | 0:18:12 | |
Now, this is a concrete diving board | 0:18:14 | 0:18:16 | |
so if I feel that he's likely to fall and hurt himself, | 0:18:16 | 0:18:19 | |
I'm going to have to stop him. You can see how much he's shaking. | 0:18:19 | 0:18:22 | |
I just can't do this, Megan. | 0:18:25 | 0:18:26 | |
Tim can't control his fear, as his brain is making him feel scared | 0:18:26 | 0:18:30 | |
to keep him away from danger. | 0:18:30 | 0:18:33 | |
This is because your brain is made up of lots of different bits, | 0:18:33 | 0:18:36 | |
and there's a special bit that feels fear called the amygdalae. | 0:18:36 | 0:18:39 | |
When you're up high, your eyes send a signal to your brain | 0:18:39 | 0:18:42 | |
so you know you where you are. | 0:18:42 | 0:18:43 | |
Then your amygdalae check with your memory banks | 0:18:43 | 0:18:45 | |
to see what you know about heights. | 0:18:45 | 0:18:47 | |
For most people, your amygdalae decide that | 0:18:47 | 0:18:50 | |
you are in danger of falling and they'll make you feel scared. | 0:18:50 | 0:18:53 | |
This then triggers signals to your adrenal glands to start working | 0:18:53 | 0:18:56 | |
and then you get you ready to run away. | 0:18:56 | 0:18:59 | |
Tim, you were just so shaky | 0:18:59 | 0:19:00 | |
I think there was a real risk of you falling. | 0:19:00 | 0:19:02 | |
I'm not happy with you carrying on. | 0:19:02 | 0:19:04 | |
I don't want you to hurt yourself. | 0:19:04 | 0:19:05 | |
We need to keep you going for Super-Test Three. | 0:19:05 | 0:19:08 | |
-Aw, you care! -I care. | 0:19:08 | 0:19:09 | |
Tim's fear of heights eventually proved too much | 0:19:11 | 0:19:14 | |
and he attempted only two of the moves Dr Megan had planned. | 0:19:14 | 0:19:17 | |
But this is a normal human reaction. | 0:19:17 | 0:19:19 | |
Now Dr Megan wants to see how Eskil reacts. | 0:19:19 | 0:19:22 | |
So for this one, if you make your way to the end of the diving board | 0:19:23 | 0:19:27 | |
and just stand still for about ten seconds. | 0:19:27 | 0:19:29 | |
He seems completely comfortable. | 0:19:34 | 0:19:36 | |
Even just how quickly he walked to the end of the diving board. | 0:19:36 | 0:19:40 | |
So, how will Eskil get on standing on one leg, | 0:19:40 | 0:19:43 | |
which is as far as Tim got in this Super-Test? | 0:19:43 | 0:19:46 | |
In your own time. | 0:19:46 | 0:19:47 | |
So even trying to balance on one leg at ground level is really difficult. | 0:19:49 | 0:19:53 | |
This is a seriously dangerous challenge. | 0:19:58 | 0:20:01 | |
Even in your local pool, you should just NOT try this at home. | 0:20:01 | 0:20:04 | |
You've been amazing so far. | 0:20:06 | 0:20:08 | |
What I'd like you to do for the next challenge is stand | 0:20:08 | 0:20:10 | |
with your heels over the edge of the diving board, facing back at me. | 0:20:10 | 0:20:14 | |
Just getting into position for this move is dangerous. | 0:20:18 | 0:20:21 | |
Eskil's ten metres up but he doesn't seem fazed at all. | 0:20:21 | 0:20:25 | |
This is extremely uncomfortable to watch. | 0:20:27 | 0:20:29 | |
It might be uncomfortable to watch, | 0:20:31 | 0:20:33 | |
but Eskil completes the move as if he's standing at ground level. | 0:20:33 | 0:20:37 | |
So it's been absolutely incredible watching you so far. | 0:20:38 | 0:20:41 | |
-Do you feel ready to take the next challenge? -Yeah, I'll do it. | 0:20:41 | 0:20:44 | |
Do you feel that you could do a handstand up here? | 0:20:44 | 0:20:47 | |
Definitely, I'll do it. | 0:20:47 | 0:20:48 | |
Eskil didn't think twice about that! | 0:20:50 | 0:20:52 | |
He's showing no fear about performing this handstand at all. | 0:20:52 | 0:20:56 | |
Human instinct is not to do this at all. | 0:20:58 | 0:21:01 | |
It's absolutely terrifying just standing up here. | 0:21:02 | 0:21:05 | |
This is... | 0:21:15 | 0:21:16 | |
Even at ten metres high, Eskil has so little fear | 0:21:18 | 0:21:20 | |
he confidently performs an incredibly dangerous handstand. | 0:21:20 | 0:21:24 | |
Completely in awe of what he's managing up here. | 0:21:29 | 0:21:32 | |
That was so impressive. How do you feel in yourself now? | 0:21:32 | 0:21:36 | |
This makes me happy. | 0:21:36 | 0:21:38 | |
Eskil wasn't at all scared | 0:21:38 | 0:21:39 | |
and easily managed to complete all of Dr Megan's four moves. | 0:21:39 | 0:21:44 | |
Unlike me! But I've heard of a man who would have loved it. | 0:21:44 | 0:21:47 | |
Charles Blondin was born in France almost 200 years ago. | 0:21:48 | 0:21:52 | |
When he was just five years old, | 0:21:52 | 0:21:54 | |
he started performing as an acrobat and was soon travelling the world. | 0:21:54 | 0:21:58 | |
When he saw the mighty Niagara Falls in America, | 0:21:58 | 0:22:00 | |
Charles wanted to be the first person to cross it on a tightrope. | 0:22:00 | 0:22:04 | |
Thousands of people watched as he attempted this incredible feat | 0:22:04 | 0:22:07 | |
across the waterfall on only a thin rope. | 0:22:07 | 0:22:10 | |
And he did it! Not just once, but again blindfolded. | 0:22:10 | 0:22:14 | |
Then again, carrying a man on his back. | 0:22:14 | 0:22:16 | |
And yet again, stopping in the middle to balance on a chair! | 0:22:16 | 0:22:20 | |
Dr Megan is combining balance and fear | 0:22:24 | 0:22:26 | |
in her third and most extreme test. She's taken Tim and Eskil | 0:22:26 | 0:22:31 | |
to some of the highest cliff faces in the world. | 0:22:31 | 0:22:34 | |
This is the unique Grand Canyon, Arizona. | 0:22:34 | 0:22:37 | |
From where we are on this ridge down to the Colorado river below, | 0:22:37 | 0:22:41 | |
it's a 1,200 metre drop. | 0:22:41 | 0:22:44 | |
This is a very serious and potentially dangerous challenge. | 0:22:44 | 0:22:48 | |
In this terrifying test, | 0:22:50 | 0:22:51 | |
Dr Megan has secured a chair to the Grand Canyon | 0:22:51 | 0:22:55 | |
and wants to see whether Tim and Eskil can do a handstand | 0:22:55 | 0:22:57 | |
on top of it, and on the edge of this 1,200-metre-high cliff. | 0:22:57 | 0:23:02 | |
It is a seriously dangerous undertaking. | 0:23:04 | 0:23:08 | |
They're both being connected up to a harness, | 0:23:08 | 0:23:10 | |
rigged to a special crane, | 0:23:10 | 0:23:12 | |
and I've got an expert in climbing on stand-by. | 0:23:12 | 0:23:14 | |
If they were to lose their balance, | 0:23:14 | 0:23:16 | |
I'd be able to stop them plummeting right down to the bottom. | 0:23:16 | 0:23:19 | |
I cannot stress enough how dangerous going near the edge of a cliff is, | 0:23:19 | 0:23:24 | |
and I would not be even thinking of running this test | 0:23:24 | 0:23:26 | |
without all the experts here. | 0:23:26 | 0:23:28 | |
Even with the safety harness and climbing experts on stand-by, | 0:23:30 | 0:23:34 | |
this is still a very dangerous test - | 0:23:34 | 0:23:37 | |
and not something to be copied. | 0:23:37 | 0:23:39 | |
With the safety harness in place, Tim is up first to face the Canyon - | 0:23:39 | 0:23:42 | |
but if he couldn't manage standing on a ten-metre diving board | 0:23:42 | 0:23:45 | |
in Super-Test Two, | 0:23:45 | 0:23:47 | |
how is he going to cope with a 1,200-metre drop | 0:23:47 | 0:23:50 | |
balancing on a chair? | 0:23:50 | 0:23:52 | |
-If you look behind you, there's a chair on a platform. -Yep. | 0:23:52 | 0:23:55 | |
If you're comfortable, I was hoping you could stand on that chair. | 0:23:55 | 0:23:59 | |
Are you out of your tiny mind? Are you mad? | 0:23:59 | 0:24:02 | |
Remember you are in a safety harness, Tim. | 0:24:02 | 0:24:05 | |
If either you or I feel it's unsafe, we'll stop. | 0:24:05 | 0:24:08 | |
I will do my best, Doctor. I will do my best. | 0:24:08 | 0:24:10 | |
This is the most terrifying test so far. | 0:24:15 | 0:24:18 | |
Tim has to use all his concentration to walk to the edge - | 0:24:18 | 0:24:22 | |
and then go even higher. | 0:24:22 | 0:24:24 | |
Whoa! Incredibly, Tim has managed to climb the chair | 0:24:30 | 0:24:33 | |
and balance on the edge of this deadly drop. | 0:24:33 | 0:24:36 | |
It might be that he feels less scared cos he is wearing a harness, | 0:24:36 | 0:24:39 | |
or it could be that Tim has learned something | 0:24:39 | 0:24:42 | |
from watching Eskil over the last two tests. | 0:24:42 | 0:24:44 | |
How are you feeling, Tim? | 0:24:44 | 0:24:46 | |
I'm shaking. My legs are shaking. | 0:24:46 | 0:24:48 | |
My arms are solid. My legs are shaking. | 0:24:48 | 0:24:51 | |
So a bit shaky, then, but Tim's succeeded. | 0:24:51 | 0:24:54 | |
Dr Megan, though, hasn't finished yet. | 0:24:54 | 0:24:56 | |
Before she asks him to try the handstand finale, | 0:24:56 | 0:24:59 | |
she has one more test for him. | 0:24:59 | 0:25:00 | |
If you feel that you're able to, | 0:25:00 | 0:25:02 | |
I'd like to try and stand on one leg. | 0:25:02 | 0:25:05 | |
Are... Are you having a laugh? | 0:25:05 | 0:25:07 | |
Oh, my goodness me. | 0:25:11 | 0:25:13 | |
I'm shaking all over. This is just unbelievable. | 0:25:13 | 0:25:16 | |
It IS unbelievable. For an average person to perform this move | 0:25:17 | 0:25:21 | |
at 1,200 metres is incredible. | 0:25:21 | 0:25:23 | |
Ho, ho! That is a long way down. Can I step away now? | 0:25:25 | 0:25:29 | |
-Tim, please step away. -OK. | 0:25:29 | 0:25:31 | |
Tim has done amazingly well, | 0:25:33 | 0:25:36 | |
but he's decided this is as far as he wants to go. | 0:25:36 | 0:25:39 | |
Dr Megan will not ask him to try a handstand. | 0:25:39 | 0:25:41 | |
Now it's time for Eskil to attempt the test. | 0:25:43 | 0:25:45 | |
He normally performs without a harness but for this test, | 0:25:45 | 0:25:48 | |
he has agreed to wear one under his suit to catch him if he falls. | 0:25:48 | 0:25:51 | |
But Eskil has no fear of falling. | 0:25:54 | 0:25:57 | |
He's even asked for more chairs to make the test more difficult. | 0:25:57 | 0:26:01 | |
To do this test, he's asked for complete silence. | 0:26:01 | 0:26:04 | |
He must focus all his concentration. Anything less could be fatal. | 0:26:05 | 0:26:09 | |
Remember, even doing this with one chair at home | 0:26:12 | 0:26:14 | |
is extremely dangerous and should not be attempted - | 0:26:14 | 0:26:17 | |
but on the edge of the Grand Canyon?! | 0:26:17 | 0:26:19 | |
And unbelievably, he's now added a third chair. | 0:26:22 | 0:26:25 | |
He's made it to the top of the chair stack - | 0:26:25 | 0:26:28 | |
but can he now take the ultimate test and perform a handstand? | 0:26:28 | 0:26:31 | |
At this height, any normal person would be feeling | 0:26:33 | 0:26:36 | |
an intense fear of falling - | 0:26:36 | 0:26:37 | |
but performing a handstand over this 1,200 metre drop, | 0:26:37 | 0:26:41 | |
Eskil is as steady as a rock. | 0:26:41 | 0:26:44 | |
That is extraordinary, isn't it? | 0:26:44 | 0:26:46 | |
It's absolutely magnificent. | 0:26:46 | 0:26:48 | |
Eskil has done it - one man balanced on three stacked chairs | 0:26:48 | 0:26:52 | |
at the edge of the Grand Canyon. | 0:26:52 | 0:26:54 | |
It's an absolutely incredible performance! | 0:26:54 | 0:26:57 | |
Tim did manage to overcome his fear | 0:26:58 | 0:27:00 | |
and stand on one leg on one chair - | 0:27:00 | 0:27:02 | |
but Eskil really has taken this Super-Test to new heights. | 0:27:02 | 0:27:07 | |
Eskil, that was a phenomenal example of physical and mental strength. | 0:27:07 | 0:27:11 | |
How do you feel now? | 0:27:11 | 0:27:13 | |
This is probably the best feeling I can achieve in my life. | 0:27:13 | 0:27:16 | |
What you've done is truly extraordinary. | 0:27:16 | 0:27:19 | |
If I had not seen that with my own eyes, I would not have believed it. | 0:27:19 | 0:27:22 | |
I came looking for a superhero, | 0:27:23 | 0:27:26 | |
a real-life man with super balance and absolutely no fear. | 0:27:26 | 0:27:29 | |
I found one. Eskil Ronningsbakken, you are superhuman! | 0:27:29 | 0:27:33 | |
