0:06:02 > 0:06:06Wow, there was a woman in France who lived to be 122 years old!
0:06:06 > 0:06:07That's unbelievable.
0:06:07 > 0:06:11That is a good age, Doctor, but I know someone a little closer to home
0:06:11 > 0:06:13who's celebrating their birthday today.
0:06:13 > 0:06:16Oh, no! The professor's birthday!
0:06:16 > 0:06:18- I totally forgot! - Not to worry, Doctor.
0:06:18 > 0:06:20I've got a big surprise planned.
0:06:20 > 0:06:23Triple chocolate marshmallow fudge cake.
0:06:23 > 0:06:26Oh! The professor's favourite.
0:06:26 > 0:06:28Oh, you're a lifesaver, Colin.
0:06:28 > 0:06:29Well, I do my best, Dr Knowles.
0:06:29 > 0:06:31- Ouch!- Lads, lads!
0:06:31 > 0:06:34You'll never guess what day it is today. Lads? Hello?
0:06:34 > 0:06:37Oh, crumpets.
0:06:37 > 0:06:40This is Brain Freeze!
0:06:40 > 0:06:42With Dr Knowles,
0:06:42 > 0:06:45Professor McCork
0:06:45 > 0:06:48and Colin the floor manager.
0:06:49 > 0:06:52Stand by!
0:06:59 > 0:07:02- Hi, folks, and welcome to Brain Freeze.- It's time to reveal...
0:07:02 > 0:07:05Today's Big Question!
0:07:05 > 0:07:09And today we're asking, what is the oldest living thing?
0:07:09 > 0:07:12It could be from the animal kingdom, the plant kingdom...
0:07:12 > 0:07:13Or the "handsome scientist
0:07:13 > 0:07:16"celebrating a very special day" kingdom.
0:07:16 > 0:07:19- Eh? Any idea, lads? - SHE CLEARS THROAT
0:07:19 > 0:07:21For most creatures, life is very shot.
0:07:21 > 0:07:24An adult mayfly can live for as little as 30 minutes.
0:07:24 > 0:07:27Humans, on the other hand, live to an average of around 80 years.
0:07:27 > 0:07:31You think that's old? Check these fellas out.
0:07:31 > 0:07:35Galapagos giant tortoises can live for up to 200 years
0:07:35 > 0:07:38and there are some whales who have been known to live just as long.
0:07:38 > 0:07:40Sounds like a lot of candles.
0:07:40 > 0:07:43But for plants, life can stretch out even longer,
0:07:43 > 0:07:45almost unimaginably longer.
0:07:45 > 0:07:48Well, hold that thought, Dr Knowles, cos we need to take a quick cake...
0:07:48 > 0:07:50Break! Sorry, break.
0:07:51 > 0:07:54And we're clear!
0:07:55 > 0:07:58Colin, how are you going to make a cake out of that?
0:07:58 > 0:07:59Not to worry, Doctor.
0:07:59 > 0:08:01I've got everything under control.
0:08:03 > 0:08:06# Working hard, keep pushing, boy
0:08:06 > 0:08:08# You know the clock is ticking
0:08:08 > 0:08:11# You can be the best, the number one
0:08:11 > 0:08:14# Rise up to the top I'm going to win... #
0:08:14 > 0:08:16- BELL RINGS - Oh, crumpets!
0:08:16 > 0:08:19Positions, everyone!
0:08:19 > 0:08:22Welcome back, Brain Freezers. Leona asks,
0:08:22 > 0:08:24"What about trees? Don't they live for really long?"
0:08:24 > 0:08:26They sure do, Leona.
0:08:26 > 0:08:29The oldest tree on record was this bristlecone pine,
0:08:29 > 0:08:32found in the White Mountains of California.
0:08:32 > 0:08:35It's an estimated 5,062 years old.
0:08:35 > 0:08:38Yeah, I bet you nobody ever forgot ITS birthday.
0:08:38 > 0:08:40It began life during the Bronze Age,
0:08:40 > 0:08:42lived right through the time of the Roman Empire,
0:08:42 > 0:08:44and still towers over us today.
0:08:44 > 0:08:45But, believe it or not, folks,
0:08:45 > 0:08:47there's something even older than that.
0:08:47 > 0:08:49It's time to reveal...
0:08:49 > 0:08:52Today's Big Answer!
0:08:52 > 0:08:54So what is the oldest living thing?
0:08:54 > 0:08:56Oh, it'll be me soon if we don't hurry up and finish it.
0:08:56 > 0:08:59Although it reproduces in a different way to most plants -
0:08:59 > 0:09:00by cloning itself -
0:09:00 > 0:09:03the oldest living thing is Neptune grass,
0:09:03 > 0:09:06a type of sea grass found deep in the Mediterranean.
0:09:06 > 0:09:11Parts of the colony are estimated to be at least 100,000 years old.
0:09:11 > 0:09:14- So that's all for today on Brain Freeze!- Yeah, whatever.
0:09:14 > 0:09:16See you next time.
0:09:16 > 0:09:19And we're clear!
0:09:19 > 0:09:21- Nice work, people.- And about time.
0:09:21 > 0:09:23See you later, pals. I'm off.
0:09:23 > 0:09:26Oh! Oh! Don't leave just yet, Professor.
0:09:26 > 0:09:28- Eh?- We've got a little surprise for you.
0:09:28 > 0:09:30BOTH: Happy birthday!
0:09:30 > 0:09:33Oh, you remembered! Brilliant! And you got me, erm...
0:09:33 > 0:09:35Some sort of, erm...
0:09:35 > 0:09:39- What is it, Dr Knowles? - It's a cake, Professor.
0:09:39 > 0:09:40Colin made it for you.
0:09:40 > 0:09:43Ah, right, a cake. That's brilliant, that is, Colin.
0:09:43 > 0:09:46Ah, fair play, I knew you wouldn't forget.
0:09:46 > 0:09:49- # For he's a jolly good fellow... # - I love this song.
0:09:49 > 0:09:53# For he's a jolly good fellow For he's a jolly good fellow
0:09:53 > 0:09:55- # And so say all of us. # - Wahey!
