My search for superhumans has brought me here, to Hollywood.

0:00:180:00:21

But where I'm going is a world away

0:00:210:00:22

from the bright lights of the movies,

0:00:220:00:24

cos I'm going into the darkness.

0:00:240:00:27

It's really dark down here and really creepy.

0:00:290:00:31

And if I didn't have my torch I'd probably

0:00:310:00:33

bang my head on one of these jagged rocks.

0:00:330:00:35

To see down here without any light at all, you'd need some sort

0:00:350:00:39

of incredible night vision or the powers of a superhero.

0:00:390:00:42

'A superhero like Daredevil!

0:00:430:00:45

'Though blind, Daredevil's incredible sonar sense gives him

0:00:450:00:49

'powers far beyond sighted people.'

0:00:490:00:52

Well, I've heard of a real-life Daredevil!

0:00:520:00:54

A blind man who defies science!

0:00:540:00:56

A man who uses an ability that we thought

0:00:560:00:58

only existed in the animal kingdom.

0:00:580:01:01

After losing his sight completely as a child,

0:01:020:01:06

American Juan Ruiz did something amazing.

0:01:060:01:08

With incredible determination, he set out to teach himself

0:01:080:01:12

to see with sound just like bats and dolphins do.

0:01:120:01:16

Juan's astonishing ability is way beyond human capabilities,

0:01:160:01:19

so is Juan a real-life superhuman?

0:01:190:01:22

And here he is. It's a pleasure to meet you.

0:01:230:01:26

It's a great pleasure to meet you as well.

0:01:260:01:28

Can I turn off this light as ask you to navigate us

0:01:280:01:31

out of here?

0:01:310:01:32

I had no idea you even had a light.

0:01:320:01:34

Because you're completely blind, is that right?

0:01:340:01:36

That's correct. I do not see anything at all

0:01:360:01:38

because what I have actually done is

0:01:380:01:40

I have trained my brain to see by using sound.

0:01:400:01:44

That's absolutely incredible.

0:01:440:01:45

-I'm going to turn it off now. There we go.

-All right!

0:01:450:01:48

-Now you get us out of here.

-Excellent! Follow me.

-OK.

0:01:480:01:51

-Juan, you've got me back outside again. That's good news.

-Sure is.

0:01:540:01:57

Now what I'd like to do is I'd like to ask you to take part

0:01:570:02:00

in three super tests to test your superhuman abilities.

0:02:000:02:03

A superhuman versus...

0:02:030:02:05

Well, it's me...versus me. You on for that?

0:02:050:02:08

Oh, I'm excited! Let's do it!

0:02:080:02:10

-OK, let's get started.

-Let's do it.

0:02:100:02:12

This is Dr Megan John, she's an expedition doctor

0:02:120:02:15

and has kept people alive in some of the most dangerous environments.

0:02:150:02:19

She's devised three super tests to discover how Tim

0:02:210:02:24

and Juan react differently without their eyesight.

0:02:240:02:27

For Super Test One, Dr Megan has brought Tim

0:02:300:02:33

and Juan to Los Angeles, California.

0:02:330:02:35

It's the home of Hollywood,

0:02:350:02:36

where the biggest movies on the planet are made,

0:02:360:02:39

and a city where the sun always shines.

0:02:390:02:41

But it's fair to say that this test has a real dark side.

0:02:410:02:44

So, guys, for my Super Test One,

0:02:440:02:46

I've brought you to this real life Hollywood film studio.

0:02:460:02:50

-Wow!

-Awesome

0:02:500:02:52

I want to see how the two of you manage to navigate your way around

0:02:520:02:55

-in complete darkness.

-Oh, that sounds easy!

0:02:550:02:57

It's not quite as simple as it seems.

0:02:570:02:59

Oh, it never is.

0:02:590:03:00

It certainly isn't,

0:03:020:03:03

because they'll have to get from one side of this special Hollywood set

0:03:030:03:06

to the other in total darkness and without touching any of the props.

0:03:060:03:10

Moving around in complete darkness can be extremely dangerous.

0:03:100:03:14

Now there aren't any Hollywood super-villains hiding in there,

0:03:140:03:18

but any obstacle in the dark can do serious damage

0:03:180:03:21

and these props are almost impossible to avoid without sight.

0:03:210:03:25

Some are low while others are hanging from the ceiling.

0:03:250:03:28

Tim and Juan are at risk of tripping and falling,

0:03:280:03:31

so they'll need helmets and padding.

0:03:310:03:34

But that's not all Dr Megan is going to ask them to wear.

0:03:340:03:37

OK, so, Tim, so when you've put on all your safety equipment,

0:03:370:03:40

I'm going to be fitting the two of you with your blindfolds.

0:03:400:03:42

Oh, but I have my permanent blindfold on already.

0:03:420:03:45

Unfortunately, this is a scientific experiment

0:03:450:03:47

so anything I do to Tim, I also need to do the same to you.

0:03:470:03:50

All right, that makes sense.

0:03:500:03:51

I'm going to be recording three pieces of data. I'll be timing you,

0:03:510:03:54

seeing how long it takes you to complete the challenge,

0:03:540:03:57

I'll also be recording how many objects you knock into.

0:03:570:04:00

And finally, I'm interested in seeing how hard your brain is having to work

0:04:000:04:04

to complete this test,

0:04:040:04:05

so I'll be fitting the two of you with these special headbands

0:04:050:04:08

which will record the electrical waves that your brain sends out.

0:04:080:04:11

-Are you both ready to go?

-Yes!

-Yeah! Yeah, let's do it.

-OK.

0:04:110:04:14

When you're plunged into total darkness, your first instinct

0:04:150:04:19

is to use touch to navigate, so you'll stretch out your arms

0:04:190:04:23

to feel for things in front of you. You'll become scared

0:04:230:04:26

and disorientated and you'll walk in circles.

0:04:260:04:29

Because your eyes help you balance, you'll begin to walk

0:04:290:04:32

in a crouching position to be lower to the ground in case you fall.

0:04:320:04:36

You could fall or bump into things

0:04:360:04:38

and get a nasty cut or bruise yourself on a hard object.

0:04:380:04:41

The worst case is that you could hit your head,

0:04:410:04:44

and develop concussion and concussion can be fatal.

0:04:440:04:47

Because there's no light in the room, we're filming this test

0:04:470:04:50

with special cameras that can see in the dark.

0:04:500:04:53

OK, Tim, in you go.

0:04:530:04:56

OK, Super Test One, find the curtain.

0:04:560:05:00

Oh! Oh! That's a funny old thing.

0:05:000:05:03

That's, er, obviously an inflatable thing.

0:05:030:05:06

Not a good start for Tim who enters the room

0:05:060:05:08

and immediately collides with an inflatable column.

0:05:080:05:11

Ow! That's something else.

0:05:110:05:12

So he's put his arms out and he's feeling his way around

0:05:120:05:16

to try and give him some more idea of where he's going.

0:05:160:05:19

Going forward now.

0:05:190:05:21

Ow! Something else! What was that?

0:05:210:05:23

I'm hearing something

0:05:230:05:24

Oh, now that's gone.

0:05:240:05:26

Because Tim can't see, he's relying more heavily

0:05:260:05:29

on his ears picking up sounds from the room around him.

0:05:290:05:32

Sound reaches the ears in waves which are channelled inside your ear

0:05:320:05:36

by the bit on the outside called the pinna.

0:05:360:05:39

Once inside your ear,

0:05:400:05:41

the sound waves hit your eardrum, making it vibrate.

0:05:410:05:45

These vibrations travel to your inner ear,

0:05:450:05:48

which sends signals to the brain.

0:05:480:05:51

Your brain then works out what the sound is and where it's coming from.

0:05:510:05:55

Sound waves bounce off hard surfaces,

0:05:550:05:58

which is why we can hear echoes,

0:05:580:05:59

especially in places with hard walls.

0:05:590:06:01

So how is Tim getting on without his sight?

0:06:040:06:06

There's something there. That's another one of those crazy columns.

0:06:060:06:09

He's looking a little bit confused.

0:06:090:06:12

That can't be the first column, can it?

0:06:120:06:14

He's quite disorientated by this experiment.

0:06:140:06:16

Oh, that's something there.

0:06:160:06:19

That's a small...foam...cube!

0:06:190:06:23

Tim is supposed to be avoiding the obstacles,

0:06:230:06:26

but instead he's touching all of them.

0:06:260:06:28

What's that?

0:06:280:06:29

Ah! That's balloons!

0:06:290:06:31

He's also lowering his centre of gravity, spreading his legs out,

0:06:310:06:34

to keep himself stable.

0:06:340:06:36

Ah, that's a corner. I've hit a corner in the room.

0:06:360:06:39

Right, that's not a good sign.

0:06:390:06:41

Let's just try and let's try and work this out.

0:06:410:06:43

So, Tim's really disorientated,

0:06:430:06:45

he's actually quite near the finish point but he's got no idea any more,

0:06:450:06:48

so he's kind of walking back into the middle of the room.

0:06:480:06:52

I could just be going round in circles.

0:06:520:06:55

Your eyesight is extremely important for you to work out

0:06:550:06:58

where you are and which direction you're going in.

0:06:580:07:01

As you pass objects, your eyes send images to the visual cortex

0:07:010:07:05

in your brain, where they are placed on a mental map.

0:07:050:07:09

When you turn left or right, your brain uses objects you can see,

0:07:090:07:12

to work out how much you've turned.

0:07:120:07:15

But without your eyesight, your brain finds it difficult

0:07:150:07:17

to tell how far you have turned or whether you have been there before.

0:07:170:07:21

Hmm! I wonder if Tim's managed to get his bearings yet?

0:07:230:07:26

That's another wall, that's not a curtain.

0:07:260:07:28

Ow!

0:07:280:07:29

There's that rock again, hang on.

0:07:290:07:31

Tim is now back at the start, but will he even notice?

0:07:320:07:36

There's another...

0:07:360:07:38

Either that's the same rock again or I really am going round in circles.

0:07:380:07:44

He's now right back at the beginning where he started from.

0:07:440:07:48

Now this is where I came in.

0:07:480:07:50

I think he's probably feeling a bit disappointed.

0:07:500:07:52

OK, let's try this again. I'm going round the rock...forward.

0:07:520:07:58

The longer he goes without hitting an obstacle,

0:07:580:08:01

because he knows I've put obstacles in there,

0:08:010:08:03

it's almost like the more apprehensive he gets.

0:08:030:08:06

There's the ball.

0:08:060:08:07

When he reaches an obstacle, particularly one he's seen before,

0:08:070:08:11

his brainwave activity does go a bit lower.

0:08:110:08:13

The longer Tim's in the room,

0:08:130:08:15

the more this becomes an experiment about how good his memory is,

0:08:150:08:18

rather than how good he is at using his senses.

0:08:180:08:21

Oh, wow! That's a tree. I've not found that before.

0:08:210:08:23

You can see that as soon as that happened,

0:08:230:08:26

brainwave activity went up.

0:08:260:08:27

As soon as he knows it's a safe thing that's not going to hurt him,

0:08:270:08:30

it relaxes back down again.

0:08:300:08:32

TIM EXHALES

0:08:320:08:33

Oh, that's new as well.

0:08:350:08:36

That's a fairly solid object.

0:08:360:08:38

When he hit the rock, there as a peak in brainwave activity.

0:08:380:08:41

He's reached a road sign, there was another peak.

0:08:430:08:46

OK, so this is an area we've not been in before.

0:08:460:08:48

He doesn't realise it, but the finish is just one step to his left now.

0:08:480:08:53

That's a curtain!

0:08:550:08:56

He's just hit the end, so I'm just going to get him out.

0:08:560:08:58

Now is that a different curtain?

0:08:580:09:00

Tim, it's the right curtain!

0:09:000:09:01

-It's the right curtain!

-It's the right curtain!

0:09:010:09:04

I've made it! I've found the curtain.

0:09:040:09:06

-You've made it!

-How exciting is that?!

0:09:060:09:07

I think I went round in circles a lot.

0:09:070:09:09

-I'm going to take your blindfold off, OK?

-OK.

0:09:090:09:12

Now the bright lights will be a bit much for you to get used to.

0:09:120:09:14

Might have to take a second on that.

0:09:140:09:16

-Keep your eyes closed for a second.

-Ow!

0:09:160:09:18

That's not very nice.

0:09:180:09:19

Oh, wow! That's really bright, isn't it?

0:09:190:09:22

Oh-h!

0:09:230:09:24

Oh, I'm there. There we go, I can see you now.

0:09:260:09:30

Tim did indeed walk around in circles.

0:09:300:09:32

He took seven minutes to cross the room and touched 30 objects.

0:09:320:09:34

'Oh, that's new as well!'

0:09:340:09:36

The results of Megan's mind-band showed that Tim found

0:09:360:09:39

the whole experience challenging and disorientating.

0:09:390:09:43

Juan is up next.

0:09:430:09:44

Will he be able to use his amazing abilities

0:09:440:09:46

to complete this challenge?

0:09:460:09:48

OK, in you go!

0:09:480:09:49

All right, well, I know two things about what I'm about to do,

0:09:500:09:53

and that is I'm going through one curtain

0:09:530:09:56

and then coming out on the other end through another curtain.

0:09:560:09:59

Immediately Juan starts making a clicking noise.

0:10:060:10:09

And, incredibly, ducks under a lampshade

0:10:090:10:12

as if he could see it, but he can't!

0:10:120:10:16

Is this noise something to do with Juan's Super Human skills?

0:10:160:10:19

Now remember, Juan hasn't even seen any of these obstacles either.

0:10:190:10:22

Tim was frightened that the obstacles were going to hurt him.

0:10:220:10:25

Juan's walking around quite quickly

0:10:250:10:28

That doesn't sound like a curtain!

0:10:280:10:30

Juan cannot see the wall and has not touched it,

0:10:300:10:32

yet he knows it's not a curtain.

0:10:320:10:35

How is he doing this?

0:10:350:10:36

You'll notice that the most obvious difference between his approach

0:10:360:10:40

and Tim's is that Tim immediately put his hands up to protect himself.

0:10:400:10:43

Juan's got his hands down by his side and is very relaxed.

0:10:430:10:47

Fine, fine, fine...

0:10:470:10:49

He's just made the curtain, I'm going to go and get him out.

0:10:530:10:56

Juan completed Super Test One in an incredible 1 minute 50 seconds

0:10:560:11:00

and touched only one object.

0:11:000:11:03

Remember, it took Tim five minutes longer and he touched 30 objects.

0:11:030:11:07

Juan's mindband results show that he found this ridiculously easy.

0:11:070:11:11

So how is he doing it?

0:11:110:11:13

When you stepped into the room you paused for a moment

0:11:130:11:16

and started making these funny noises. What was that?

0:11:160:11:19

I was clicking, I was making a click sound, just...

0:11:190:11:22

CLICKS

0:11:220:11:23

..so that I could get my orientation

0:11:230:11:25

because that click bounces off the walls

0:11:250:11:28

that are all over the room so that I get the dimensions of the room.

0:11:280:11:32

What Juan is describing is something called echolocation

0:11:330:11:36

and it's a way of using sound waves to see

0:11:360:11:39

just as bats and dolphins do.

0:11:390:11:42

When you make a noise, the sound waves come out of your mouth

0:11:420:11:44

and spread all around you.

0:11:440:11:47

They hit objects and are bounced back to your ears.

0:11:470:11:50

Like this - these are called echoes.

0:11:500:11:53

Your brain usually ignores the echoes from your own voice,

0:11:530:11:56

but Juan's brain is different.

0:11:560:11:59

Juan has learnt to use echoes from his clicking noise

0:11:590:12:02

to work out where objects are and what shape they are.

0:12:020:12:06

Every click allows Juan to see an object with his ears

0:12:060:12:09

but only while the echo lasts.

0:12:090:12:12

Being in the dark for even ten minutes really affected my eyes.

0:12:140:12:19

So imagine how your eyes would cope after months in the darkness.

0:12:190:12:23

Tragedy struck 33 miners in Chile, when a tunnel collapsed,

0:12:230:12:28

trapping them 700 metres underground.

0:12:280:12:31

They were sent food and water so they could survive,

0:12:310:12:34

but living in constant darkness can make you feel very depressed.

0:12:340:12:38

The miners needed to keep to a daily routine so they knew

0:12:380:12:41

when to go to bed and when to get up without sunlight.

0:12:410:12:44

They also sang songs to keep their spirits up.

0:12:440:12:47

After two months, rescue teams were able to lift them out.

0:12:470:12:51

The miners wore sunglasses for several days afterwards

0:12:510:12:54

to protect their eyes while they adjusted to the daylight.

0:12:540:12:57

For the second Super Test, Dr Megan has taken Tim and Juan

0:12:590:13:03

out of Hollywood down to one of the busiest piers in the world

0:13:030:13:07

at Santa Monica.

0:13:070:13:10

For my Super Test Two,

0:13:100:13:11

I want to study Juan's echolocating abilities still further.

0:13:110:13:14

So I want to see if the two of you can identify objects

0:13:140:13:18

when you go past them just by using the way they reflect soundwaves.

0:13:180:13:22

And I want to see how you do that in a real live situation.

0:13:220:13:25

In this Super Test, Juan and Tim will have

0:13:290:13:32

to correctly identify five objects on the pier

0:13:320:13:35

and once again they will be blindfolded.

0:13:350:13:38

These objects will be big, small, hard and soft.

0:13:380:13:41

So Tim is going to need some help.

0:13:410:13:43

Go ahead and click.

0:13:440:13:46

That's really gone

0:13:530:13:54

and it's not just because it's down below, I can really...

0:13:540:13:57

It's gone, it's not there.

0:13:570:13:59

It's not at the face level where it's at now.

0:13:590:14:01

The sound is not bouncing directly off of it.

0:14:010:14:05

When you are clicking, you really can feel

0:14:050:14:08

that there's something coming back at you but when it's not there,

0:14:080:14:12

I know there's nothing coming back at me

0:14:120:14:15

Tim's beginning to get the hang of it

0:14:150:14:17

but there is still a great danger that he will get a nasty bump

0:14:170:14:20

from a hard object. There's enough noise and bustle out there

0:14:200:14:24

to really confuse him.

0:14:240:14:26

From Super Test One, I saw how incredible, Juan,

0:14:260:14:29

your ability to avoid bumping into things was,

0:14:290:14:31

so I don't think you need to do this test in protective gear.

0:14:310:14:34

Tim. You on the other hand - full safety equipment.

0:14:340:14:38

OK.

0:14:380:14:40

We've asked Tim and Juan to identify exactly the same objects

0:14:400:14:45

along one of the busiest piers in the world,

0:14:450:14:47

just from the way they sound. Tim is up first.

0:14:470:14:50

Stop where you are. OK, now slightly to your right

0:14:500:14:53

is the object I'd like you to try and identify.

0:14:530:14:56

Yeah, that's there.

0:14:590:15:01

I've touched that with my elbow.

0:15:010:15:04

Unable to find the position quick enough,

0:15:040:15:07

Tim has touched the bin before he's even clicked.

0:15:070:15:10

Tim will not be allowed to guess this one.

0:15:110:15:15

Normally, to identify an object you'd use sight.

0:15:150:15:18

As well as that you'd use your other senses - smell, touch and hearing.

0:15:180:15:22

I've taken away his sight which is the easiest one to use,

0:15:220:15:25

so Tim's exhibiting exactly what I would expect

0:15:250:15:28

a normal human reaction to be.

0:15:280:15:29

To try to utilise all the other senses.

0:15:290:15:31

He can't help but put his hands out

0:15:310:15:34

to use feel and touch to give him an idea.

0:15:340:15:37

Who can blame him? Touch is one of our most important senses after all.

0:15:370:15:42

Your skin is covered in nerve cells called receptors

0:15:430:15:47

that send messages to your brain

0:15:470:15:48

whenever your skin touches something.

0:15:480:15:51

There are three types of receptors.

0:15:510:15:53

Some for temperature, some for pressure and some for pain.

0:15:530:15:57

When you touch an object with your fingers,

0:15:570:15:59

your pressure sensors can help you decide if is hard or soft

0:15:590:16:03

and what shape it is.

0:16:030:16:04

Your temperature sensors tell you if the object is hot or cold.

0:16:040:16:08

This is how you can tell what things are made of.

0:16:080:16:10

Now it's time for Juan's go at the bin.

0:16:130:16:15

Even though he is totally blind,

0:16:150:16:17

Juan has agreed to wear the blindfold again,

0:16:170:16:19

just to keep the test the same for him and Tim.

0:16:190:16:23

Oh, my gosh. All right so let's listen to this thing,

0:16:250:16:28

see what it is.

0:16:280:16:30

Ooh, wow.

0:16:300:16:32

Juan immediately finds the object

0:16:320:16:34

while it is still almost half a metre away from him.

0:16:340:16:36

When Tim was doing this, he was exhibiting exactly

0:16:360:16:38

what I'd expect a human to do to.

0:16:380:16:40

Putting his hands out, he couldn't help himself

0:16:400:16:42

but try to use some touch.

0:16:420:16:43

A trash can!

0:16:430:16:45

Ah!

0:16:450:16:46

It's nice and round and it's got the height of...

0:16:460:16:49

A trash can?

0:16:490:16:50

A trash can, exactly!

0:16:500:16:52

Really impressive, sir.

0:16:520:16:54

Next challenge - a vendor's booth selling t-shirts.

0:16:540:16:57

I've hit something with my head and that's probably not a good sign.

0:17:040:17:07

Once again Tim has collided with the object before finding it

0:17:070:17:10

with his clicks.

0:17:100:17:12

This doesn't seem as solid.

0:17:120:17:14

Juan's told us that not only can he orientate how large an echo is

0:17:140:17:18

using his echolocation techniques, but the density.

0:17:180:17:22

That is, how hard it is or how soft it is

0:17:220:17:24

changes the way the sound wave is reflected back

0:17:240:17:27

OK, that's the other edge. So there's edges here.

0:17:270:17:29

Oh no, maybe.

0:17:290:17:31

It's difficult because it seems to be... The sound isn't...

0:17:310:17:35

OK, Tim, let's move on now from this one.

0:17:350:17:38

Tim didn't manage to identify this one either.

0:17:380:17:41

How will Juan deal with such a large soft object?

0:17:410:17:44

OK, stop there.

0:17:440:17:46

Yes I hear it, so let's see. Let's study this obstacle.

0:17:460:17:49

Well, it's taller than me

0:17:510:17:53

but that's not too hard because I'm rather short.

0:17:530:17:55

This time Juan hears the object while he is over a metre away.

0:17:550:17:59

So straight away before I positioned him near it he said,

0:17:590:18:02

"Oh, yeah. I hear it."

0:18:020:18:04

Now, it's not making any noise, it's him hearing back those clicks.

0:18:040:18:08

See, this object is interesting because it's not very solid.

0:18:080:18:14

Different objects reflect sound waves in different ways.

0:18:150:18:19

If you were to tap on a box,

0:18:190:18:20

you could tell if it was hollow or solid,

0:18:200:18:23

or if it was made of metal or wood simply by the sound it made.

0:18:230:18:27

Amazingly, Juan's brain is able to do this just by using

0:18:270:18:30

the echoes of his click.

0:18:300:18:31

Juan's brain detects how the sound in the echo has changed

0:18:310:18:35

to work out what the objects are made of.

0:18:350:18:38

Hard objects reflect more sound than soft objects

0:18:380:18:42

and Juan's brain can detect the tiniest changes.

0:18:420:18:45

I would... You know, I would have to say this is a vendor's booth.

0:18:480:18:53

Amazing!

0:18:530:18:55

Juan is of course completely right, again.

0:18:550:18:58

About a foot in front of you is the next object I'd like you to identify.

0:18:590:19:03

Because Tim can't see, he is finding it hard to judge how far away

0:19:030:19:07

the objects are in this test.

0:19:070:19:08

Will he be able to avoid touching this one?

0:19:080:19:11

CLICKS

0:19:110:19:14

Now of course you have touched it a few times so.

0:19:140:19:16

Yeah, I can feel that there is something like, like leaves.

0:19:160:19:22

Maybe like plastic crazy foliage.

0:19:220:19:25

I don't know how to do this so my ability to get where,

0:19:250:19:29

how close it is, is quite difficult

0:19:290:19:30

so sometimes I nudge the object when I don't mean to.

0:19:300:19:33

Like I've just done it there.

0:19:330:19:34

And of course if you nudge the object you get...

0:19:340:19:37

I get some information about it.

0:19:370:19:39

Step forward. Again, again, again. And stop there.

0:19:390:19:42

It's just about 30 centimetres in front.

0:19:420:19:46

Let's see.

0:19:460:19:49

It sounds like a bush.

0:19:520:19:54

Right, Juan, you have made my test look too easy!

0:19:540:19:59

The next object is a fire hydrant

0:19:590:20:02

and Tim has found it with his stick.

0:20:020:20:04

There's something there.

0:20:040:20:05

But can he work out what it is with his click?

0:20:050:20:09

CLICKS

0:20:110:20:13

His hands are all over it. He can't help it!

0:20:160:20:18

He won't prove anything in this test, even if he guesses what it is.

0:20:180:20:22

Some sort of post.

0:20:220:20:24

Time for Juan to try - remember, he uses just his hearing

0:20:240:20:27

and he doesn't touch the object so it's a little trickier for him.

0:20:270:20:31

Oh, wow!

0:20:310:20:33

I would say this is a chair.

0:20:350:20:37

OK, so about the height of a chair. Right, well.

0:20:370:20:40

It's not just the height, because the height comes up to about here.

0:20:400:20:44

But then there's something here that is more flat

0:20:440:20:46

and then the back goes up.

0:20:460:20:47

OK, all right.

0:20:470:20:49

So I think it's a chair.

0:20:490:20:50

Because Juan uses sound waves to create an image,

0:20:500:20:53

he thinks that the barrier behind the post and the box next to it

0:20:530:20:57

are all part of the same thing,

0:20:570:20:59

which does actually resemble the shape of a chair.

0:20:590:21:02

So I think we can let him off with this one.

0:21:020:21:04

Time for the next object.

0:21:040:21:05

This is really interesting,

0:21:120:21:14

cos although it's right in front of him, he's moved to the side.

0:21:140:21:17

I'm not sure he's got any idea of that.

0:21:170:21:19

Tim's shoulder has just touched the lamp post.

0:21:190:21:21

He's not going to be allowed to guess this one either now.

0:21:210:21:25

Juan's go next, but will the shape of the railing put him off again?

0:21:250:21:29

Well, it's very thin,

0:21:310:21:34

and it's right next to the railing right here.

0:21:340:21:39

But I can put my hands straight through here right behind it.

0:21:390:21:42

When Tim was putting things forward he was just touching everything.

0:21:420:21:46

Juan was able to demonstrate beautifully without touching a thing.

0:21:460:21:50

I would say it's something like a light pole.

0:21:520:21:55

I just have no idea but I'll say a light pole.

0:21:550:21:58

You have no idea but you're guessing a lamp post?

0:21:580:22:00

It's some type of pole.

0:22:000:22:01

Juan has guessed correctly an incredible four out of five objects

0:22:010:22:06

on Santa Monica Pier using only sound.

0:22:060:22:09

It sounds like a bush.

0:22:090:22:11

And although Tim made a great attempt,

0:22:110:22:13

he couldn't get over his instinct to touch.

0:22:130:22:16

His hands just got in the way, as did his mouth.

0:22:160:22:20

I was amazed at how well Juan moved about on the pier without sight.

0:22:200:22:24

But there are some people who spend their whole lives

0:22:240:22:27

in a dark environment.

0:22:270:22:29

The Penan people live in the rainforests of Malaysia

0:22:290:22:32

in South East Asia.

0:22:320:22:33

The giant trees have very thick top branches and leaves

0:22:330:22:37

which block out the

0:22:370:22:39

sun, so the forest is very dark even during the day.

0:22:390:22:42

But the tribe are perfectly adapted to finding their way around

0:22:420:22:46

so they don't get lost.

0:22:460:22:49

They can even hunt animals in the dark, the lack of light

0:22:490:22:52

and noise helps them track their prey more easily.

0:22:520:22:55

Their senses can detect even the smallest changes in light,

0:22:550:22:59

sound, smell and temperature of the forest which outsiders can't.

0:22:590:23:03

Doctor Megan's Super Test Three is taking place

0:23:040:23:07

in Irvine Park, California.

0:23:070:23:09

And it's going to be one of the most dangerous Super Tests yet.

0:23:090:23:13

Juan has told me he can do something absolutely incredible.

0:23:130:23:18

He can mountain bike without sight.

0:23:180:23:20

Wow, that's unreal. That's absolutely incredible.

0:23:200:23:23

-Completely terrifying.

-It's exhilarating for sure.

0:23:230:23:26

Mountain biking is all about riding tough bikes

0:23:260:23:29

over even tougher terrain.

0:23:290:23:31

It requires endurance, strength and balance.

0:23:310:23:34

Risk of injury from falls and collisions is high

0:23:340:23:37

in the sport of mountain biking

0:23:370:23:40

from minor wounds to serious damage to the head and spine.

0:23:400:23:43

Even sighted mountain biking can be very dangerous.

0:23:430:23:46

If you were to fall off you could cut yourself, break bones,

0:23:460:23:50

even knock yourselves out.

0:23:500:23:51

So I've had to take a lot of safety precautions today.

0:23:510:23:54

I've got Robin, an expert mountain biker who'll be leading

0:23:540:23:58

your way down the trail.

0:23:580:23:59

I've got Corrie with all her medical equipment and expertise on standby.

0:23:590:24:04

And Tim, because you've not done this before,

0:24:040:24:06

-I'm going to ask you to practise away from the trail first.

-OK.

0:24:060:24:10

-So, guys, let's give it a go.

-Let's go!

0:24:100:24:12

Worried that Tim will seriously injure himself,

0:24:120:24:16

Dr Megan asks two members of the film crew to run alongside him.

0:24:160:24:20

But even with a team of people helping,

0:24:200:24:22

Tim almost collides with a tree.

0:24:220:24:23

I don't think it would be safe for Tim to do the trail course

0:24:260:24:29

-that we've set up for you.

-It doesn't sound like it.

0:24:290:24:31

-It seems like he'll need a lot more practice.

-I agree.

0:24:310:24:34

This super test is just too dangerous for Tim to try

0:24:340:24:38

so it looks like Juan will be doing it on his own!

0:24:380:24:41

In this test, Juan will be cycling blindfolded for 1 km

0:24:440:24:48

along the twists, turns and steep drops of this mountain forest track.

0:24:480:24:52

Using his ears, he will be following the bike in front

0:24:520:24:55

which will be making a loud clicking sound.

0:24:550:24:58

Remember, Juan is totally blind,

0:24:580:25:01

so the blindfold makes no difference to him.

0:25:010:25:03

It's simply being worn to keep him under test conditions.

0:25:030:25:07

Cycling blindfolded, downhill is incredibly dangerous.

0:25:080:25:12

Actually, totally impossible.

0:25:120:25:13

Let's face it - you will come off your bike.

0:25:130:25:16

When this happens you could cut or bruise yourself.

0:25:160:25:19

You could even break a bone. If you hit a tree at speed,

0:25:190:25:21

you could break your neck or back,

0:25:210:25:23

or you might fall off a steep slope and crack your head on a rock.

0:25:230:25:27

Serious head injuries are fatal.

0:25:270:25:30

OK, so here we are at the start line.

0:25:300:25:32

It's a really tricky course. I can't wait to see how you get on.

0:25:320:25:36

-Are you ready to go?

-Ready.

0:25:360:25:37

Off you of go.

0:25:370:25:39

Let's go!

0:25:420:25:44

Juan sets off down the hazardous track completely blind.

0:25:440:25:47

For a sighted person,

0:25:470:25:49

even attempting this blindfolded would be unthinkable.

0:25:490:25:52

Although he is listening out for the lead bike,

0:25:520:25:55

he is still using his own click to help him navigate the course.

0:25:550:25:59

Juan takes the first corner with ease.

0:25:590:26:01

But remember this is just the first of many corners and dips.

0:26:010:26:05

This course could be lethal.

0:26:050:26:08

As Juan begins to pick up speed,

0:26:080:26:10

it's hard to believe that he cannot see anything.

0:26:100:26:12

He is doing this incredible feat using only his hearing.

0:26:120:26:17

As he approaches a hairpin bend,

0:26:170:26:19

Juan almost comes off the track

0:26:190:26:21

but he quickly recovers.

0:26:210:26:22

What Juan is doing would be too dangerous for someone

0:26:240:26:27

without his skill and experience to try. This is incredible!

0:26:270:26:32

Another tight corner and Juan takes it with ease.

0:26:340:26:38

Watching how effortlessly Juan does this,

0:26:420:26:44

it's hard to believe that he can't see.

0:26:440:26:47

This road may be straight

0:26:480:26:50

but there's a serious drop to Juan's right!

0:26:500:26:53

He's on the home straight now and Dr Megan and Tim

0:27:000:27:03

are waiting to cheer him over the finish line.

0:27:030:27:05

-Wow, that's amazing!

-Congratulations!

0:27:120:27:14

Juan has finished this course in just over three minutes,

0:27:140:27:17

making his average speed a very impressive 20 kilometres an hour.

0:27:170:27:21

Juan Ruiz can identify the world around him by seeing with sound.

0:27:240:27:27

Incredibly, he does this even in the most extreme conditions.

0:27:270:27:32

There's no doubt he IS Super Human.

0:27:320:27:35

That was simply amazing, what you just did.

0:27:350:27:38

You've developed your hearing to Super Human levels

0:27:380:27:42

with what you do with it.

0:27:420:27:43

I came here to meet a real-life Daredevil.

0:27:430:27:46

I've met him. It's you.
