What we thought we’d do Chris,
is just talk you through the plan,

so you’ve got a rough idea
as to what you’re getting into.

So, the main risk is really
that the longer you spend in the water,

the risk goes up exponentially.
If you push yourself beyond the point

at which you should be coming out,
there is a real risk you could die.

Yup.

CHRIS: As you can tell,

the safety team have one or two concerns
about what I’m about to do.

So do I.

Right, this is where
we switch it on now, okay?

Somehow, I’ve been talked
into an open water swim...

Good.

...in the Arctic.

Impose your will on the sea.

Two minutes! Two minutes!

And if there’s one thing I really,
really hate...

it’s the cold.

Why am I doing this? Why am I doing this?
Why am I doing this?

-Special change of scenery.
-Epic surroundings.

I'll say, there's no mangoes falling off
the trees here!

Yeah.

As part of my mission to live longer,
I’ve traded the warmth of Australia

for the frozen north.

And along for the ride,
I’ve got these jokers.

My younger brother Liam,
and my older brother Luke.

When I invited them
to hang out at the beach,

not quite sure this is what they imagined.

Feather that clutch, mate.

Dude, I can’t feel the floor.
These boots are a bit thick.

We’ve let the worst driver
of all drive us.

-Why is Chris driving, mate?
-Are you kidding?

I’m the best driver ever, dude.

We’re here with a man who says
extreme temperatures are actually

gonna be good for me.
Sports scientist, Ross Edgley.

I mean, it doesn’t get much better
than this really, does it?

I mean, as a training ground,
as a sports lab...

I'm in my element.

I don't know
how comfortable I am with that!

Ross Edgley is one of the fittest humans
on the planet.

The kind of guy
who takes everything to the limit.

He's the only person in the world
to swim all the way around Great Britain.

And he did it in 157 days straight.

CHRIS:
But then he takes it even further...

...you know, with, like,
swimming in ice-cold water.

I believe we humans only really thrive
in the face of adversity.

You find out about your physiology,
you find out about your mentality...

and there are now theories that subjecting
your body to extreme temperatures

could even help you live longer.

And that is why I signed up
for this Arctic adventure.

Ross might love the cold,
but I'm more like Goldilocks.

Not too hot, not too cold,
I'm happiest right in the middle.

And you’d think that staying
in a comfortable temperature

is also the best way to keep healthy
for the long haul.

But new science says embracing
extreme cold, and extreme heat...

could force your body to upgrade
its defenses...

and power up
its microscopic repair systems...

which could cut the risks of disease,
and maybe add years to your life.

So, it’s time
for some serious shock therapy.

After three days of training,
Chris will attempt a cold-water swim

that's going to test his body
to the absolute limit.

Two hundred and fifty yards
across a bone-chilling Arctic Fjord,

wearing nothing but swimming trunks
and a smile.

If he can endure that, then maybe
he could fall in love with the cold...

and make it part of his life.

So, how’s your Australian physiology
coping with this?

It's in complete shock right now.
My ears are about to snap off.

They’re like little icicles
and I’m a little concerned.

This is the plunge.

Yeah.

And I want you to basically get down
to your trunks, get in,

and I just want you to experience the cold
at its rawest form.

-Yeah.
-Think of it almost like a baptism.

That’s what we’re doing.
Because you need to understand

what's going on inside the body. So...

Oh, it knows it's gonna freeze
in a second, yeah.

-Yes. Yeah. This is it.
-Yeah.

This is it. No, no, no.
But it's gonna be a shock to the body.

I’m not gonna lie.

-Yeah.
-I’m gonna be so honest with you.

To prepare for the swim,

the first step is subjecting Chris
to full immersion.

The problem is that cold water triggers
some really powerful survival mechanisms.

But if you’re training for an ice swim,
they actually work against you.

I need Chris to understand
what those reactions feel like,

and then start to tame them.

One of the first things that
we're gonna experience

is this gasp reflex.

-The body's basically just going...

Is exactly it. You wanna gasp,
perfectly normal. That is...

-It’s just self-preservation.
-Mm-hmm. Perfectly normal.

-Yeah. Once we start the timer...
-Yeah. Yeah.

...once we’re in, make no mistake,

we basically started
the timer on hypothermia,

and to put it bluntly,
consciousness and dying.

And saying, "goodbye, life."
Yeah. All right.

Oh, yeah. Here we go!

ROSS:
Before we let Chris loose in open water,

I want to see if he can get through
the initial shock

and tough it out for at least
a couple of minutes here in the harbor.

Do I reckon this warm-blooded Aussie
can do it? I don't know.

Oh, yes, this is a great idea!

-Here we go.
-Follow my lead.

All right.

-That's it. Breathe, breathe.
-Oh, boy.

-Good. Good. Really good.
-Whoo!

-Breathe.
-Wow!

Okay, there you go, okay.
There you go. So that's that gasp reflex.

You know, that hyperventilation.
Control it. Control it.

Don’t let it bully me.

Self-preservation,
your body is going, "get out!"

-But override that.

-How we feeling?
-Oh, freezing.

-Okay.
-Yeah.

-Feels like I’m in the fire.

-Okay, breathe! We are at one minute.

-So, now, what's happening?

Now we’ve got over that gasp reflex.

No, no, we haven’t.

-It's still going?
-I haven’t got over anything!

ROSS:
Someone forgot to put the hot tap on.

-Oh, God! Oh, God!
-CHRIS: As if things weren’t bad enough,

Luke and Liam, and our buddy, Mick,
have got front row seats.

Summer swim?

-Yes, boys!

Oh, God!

CHRIS: Now, why did I invite them, again?

How is it?

Oh, it’s amazing, it’s so warm in here.

What’s the level of shrinkage?

How would you feel if I said,
"Let’s put our face under?"

Okay, let's go.

-Oh, boy.
-Oh, wow!

-Terrible idea.

-Yeah. I'm impressed.

All right, I think we’ve proved our point,
right? Can we get out?

Right.
Hang on, give me 30 more seconds.

Oh, what?

Can you feel that blood going away
from your extremities?

Yeah, I can feel all sorts of pain.

-So, quick test.
-Yeah.

-Quick dexterity test for me.
-Yeah.

-How's that?
-They feel like...

-How quickly can you move your hands?
-...pins and needles!

-Shit.

-We are at...
-Awesome.

-...two minutes, 50.

-Talk to me. How are we feeling?
-I feel like I’m dying.

-Okay...

You actually probably are.

-Let’s just get out!
-No, no, no, no,

-give me 30 more seconds.

-No, don't get out.
-Stop saying that!

-Five minutes.
-Just another 30.

We're done, we're done,
you did good, man. You're good.

I don't think I can get out.

-Nice, big man, nice.
-I can't...

-Let's go.
-You got it, Chris.

My hands, I can’t feel them.

Go on, straight into push-ups, Chris!

-Yeah, yeah, yeah, yeah.

Oh, my God, is there a towel somewhere?

-I got it, I got it. Here you go.

-What’s that towel?
-What are you...

The world’s smallest towel!

-It's okay, it's a warm wind.
-Oh, God. Wow.

Fifty-year storm's coming in, guys,
we've got to get to safety!

To safely recover from the shock,
we have to bring Chris's core temperature

back to normal gradually.

Man. My toes, mate.

Keep it going, keep it going.

Yeah, good. There you go.

-Whoo!
-All right, on three.

My fingers just don’t exist right now.

ROSS:
They'll recover, don't worry about it.

That was the hardest thing I’ve ever done.

-I'm fine. Yeah, by far.

-That was...
-That was terrific.

-...the most awful thing.

You know when you, like, regret moments
in your career?

That was one, Ross.

-Wow! That’s something else, Ross.

CHRIS:
Being that cold, it’s just so intense.

And I feel like I’m outside
of my comfort zone

further than I've probably ever been.

-Do you want me to hug you?
-My arms are cold.

My arms are like freezing.

-Thank you.
-There you go.

Finger in there. Is that boiling? Yeah?

-No idea.

That was a struggle.

And out in open water,
it's only gonna get harder.

To stand any chance of doing this swim,
Chris has to start taming those reactions.

And there are scientists who believe
controlling the body’s response

to the cold could also have
huge health benefits down the line.

As I get older, one quirk
to look forward to is that my built-in

defense system could get trigger happy.

CHRIS:
Throughout the body's blood vessels,

an unwelcome surge of immune cells
can cause collateral damage...

doing more harm than good.

The resulting breakdown in tissues
and organs is called "inflammaging."

And it fuels two of the biggest killers
in the modern world.

But there’s a theory that dialing down
our reactions to the cold...

could also help to reset
that rogue immune system,

and cut the risks
of deadly disease in old age.

So, I’ve gotta subject myself
to regular blasts of icy pain,

and I might not even see the benefits
for years?

Fantastic.

Fortunately,
there is another upside

that can kick in much sooner.

After Johanna Nordblad smashed
her leg in a cycling accident,

her fractures healed,
but the pain never stopped.

It felt like fire in my bones.

I couldn't sleep.

My leg had been in agony for three years.

I was ready to try anything.

Conventional drugs didn’t cut through.

So, doctors prescribed
a radical alternative.

A new treatment, based on the theory
that cold water can scramble pain signals

before they reach the brain.

When I put my leg in the water

for the first time since the accident,
it stopped hurting.

Tears welled in my eyes, and I cried.

Johanna got her life back...

but she didn’t stop there.

She was already a free diver...

but taking on these frozen lakes...

has allowed her
to not only to endure the cold,

but to embrace it.

The treatment
took away my fear of the cold.

If you keep calm,
you can stay in much longer.

This has brought more
than just pain relief.

By swimming in cold water,
you get ill far less often.

I feel healthier and full of energy.

The right dose
of shock

could enhance your ability
to fight off infection.

And you don’t have to be an ice-diver.

In one study, people who flipped to cold
for the last 30 seconds

of their daily shower, ended up
taking almost 30 percent fewer sick days.

That’s pretty impressive.

It's good to be outside your comfort zone.

Open your mind.

Embrace the feeling of the cold.

As more benefits
come to light,

people are finding their own ways
to harness extreme temperatures.

And as we take my training
to the next level,

Ross has come up with the perfect way
to lure me back into the water.

The one thing he knows I can’t resist.

Whoo!

It’s absolutely beautiful,
but your brain’s going,

"What’s going on here?
Why are we heading to the water,

"Why are we trudging through snow?"

-You’re gonna feel alive after this.

Back in Australia, I surf a lot,
but going out in these conditions...

now, that's gnarly.

Luckily, I've got my good buddy here.

Three-time world champion surfer,
Mick Fanning.

Who Ross has roped in to keep me on track.

Coming to a place like this...

it’s such a different experience
than what we’re used to at home.

Yeah.

-It’s so easy at home, you know?
-Yeah.

You have board shorts, it’s warm,
you can park right at the beach.

When here, you gotta think
about your warmth, you gotta think

about getting through the waves and...

With the elements just so raw and real,

you have to zero in in these conditions.

Otherwise, you’ll end up
on the rocks over there,

-somewhere.
-Yeah.

Let's get on with it, shall we?

I want Chris to experience
prolonged exposure.

But in these conditions,
half an hour in his trunks could kill him.

So, this is the wetsuit test.

As he steadily cools down,
he’s gonna experience a significant loss

in muscle strength, and his coordination
is gonna go to pieces.

-I’m keeping warm,

-with Liam and Luke.
-What are they doing?

I wanna see if Chris can hold
it all together and stay mobile.

Let's see how much harder
it is to paddle, eh?

All right, here you go. Here goes Mick.

Wow!

-Little boost on the end. Epic!
-Whoo!

I started surfing
when I was about ten, ten years old.

It's not a bad obsession to have.

But this is like being on another planet.

-A pretty brutal experience.

You, go. You, go! Jump on.

It's Chris.

LUKE:
There you go! Oh, I can't believe it!

Oh! Yes!

-Oh, yes, mate!

-That's an actual turn!
-An actual good wave! Oh!

-Yeah!
-That's huge!

I’m not easily impressed
by Chris’s surfing...

-Right. Yeah. Yeah.
-...but that was pretty impressive.

To begin with,
you feel like you’re winning.

-You all right?
-It's just so hard to swim.

But eventually...

you start to get so cold.

They're so far out now.

It’s so mental out there.

I can feel it sucking the strength
out of my arms.

It’s harder to maneuver.

My balance is off...

and I'm feeling pretty vulnerable
at this point.

-He’s taking a break.
-Oh, my God.

Oof! Oh!

-I think he's...
-He got poleaxed on that one.

Oh, my God.

It's absolutely freezing.

And at this point, I’ve had enough.

-How was it?
-It was so intense.

-It's like... It's kind of scary.
-Yeah.

The storm kicked back in
and started hailing,

couldn’t even see the waves.

-The hail was hitting me in the eye.
-Yeah.

-It's a completely different, you know...
-And I’ve noticed as well...

-...game, right?
-...the wind chill. Did you feel

-that out there as well?
-For sure.

Yeah.
-Yeah.

-At the end, not catching waves...
-Yeah.

...I started to get a little colder.

And when you get cold,
it just hurts, right?

Yeah. It was... Feels like knives
in your fingers and your toes.

Generally speaking, you’d probably
do everything that you can to avoid

-a surf like that, but...
-Yeah.

...hats off to you, guys.

It was pretty wild out there.

That kind of cold is completely ridiculous
and alien to anything I've ever done.

So, the idea of now going and swimming
without all of that gear and the wet suits

and so on...

has become a really...

intense, scary reality.

ROSS: I think Chris has earned
a break from the cold.

And up here,
there’s another way to boost longevity.

At the other end of the temperature scale.

Whoo!

Ross has hooked me up
with longevity expert, Dr. Peter Attia.

All right.

It's intense.

But Peter's convinced that regular saunas
can boost my long-term health.

DR. PETER: You know,
now that we just got in here, Chris,

let's take your pulse.

All right.

DR. PETER:
Yeah, you're about 64 beats per minute.

But we've got this temperature
cranked up to about

-hundred and ninety-five degrees...
-Yeah.

DR. PETER: ...Fahrenheit.

So, let's see where you are
in a couple of minutes.

I guess I gotta get used to this heat.

Yeah, we're uncomfortable right now
because we're hot.

And in response to that,
our body is trying to cool us off.

-Yeah.
-And so, it's pumping harder

so that your heart can quickly
get the blood to the outside of your body.

And just as exercise is known to help
with cardiovascular disease,

I think sauna
has a number of those benefits as well.

-Like a workout. Yeah.
-Yeah, exactly.

Yeah, you're about 135 right now.

About twice what you were when we started.

-It also...
-It goes back to how beneficial

-stress is, right?
-Yeah. Yeah.

I mean, stressing our bodies in any way

is... It forces us to adapt
and evolve and change.

Yeah. Well, we just... Our body wants
to stay in a certain temperature range.

And right now, we're pushing ourselves
way outside that comfort zone.

And in the process of adaptation,
our body protects us by increasing

the production of these special molecules
called heat shock proteins,

which are extremely effective
in the fight against disease.

I like to think I look healthy
on the outside.

But on the inside, deep in my cells...

heaps of molecular junk piling up
from the wear and tear of age.

Hoarding all that trash could lead
to serious problems when I'm older.

But the blistering heat of the sauna
tells my body to send in a cleanup crew...

heat shock proteins.

And these tiny heroes
get to work fixing up the junk

to give my cells
the ultimate spring cleaning.

By upping my heart rate and releasing
heat shock proteins,

getting this hot can work wonders.

The two places where sauna
is having the most benefit

is in cardiovascular disease,
where it is about a 50 percent reduction

in risk of death, and Alzheimer's disease,
where it's about

-a 65, 66 percent reduction.
-Wow.

DR. PETER: Yeah, this exceeds that
of virtually any drug that we can imagine.

Incredible.

That's from simply taking
frequent saunas,

fired up to around 170 degrees Fahrenheit.

Now, that's the kind of prescription
I can handle.

But right now...

I've got some unfinished business
with the cold.

Yes, boys, how we feeling?

-Wow, mate.
-That's what I'm saying, mate.

-Yeah, Rossy!

With the swim looming,
there’s no let-up in the training.

-Are you plotting something?
-I just think...

I’m gonna be completely honest,
now we’re out here.

I just... I don’t think there’s such
a thing as too much acclimatization.

I just think we need to get you as cold
as possible, as often as possible.

Let’s go, let's go, let's go!

-All right. All right.

CHRIS: All my brothers and my friends
have done so far is laugh at me.

So, this is payback time.

-Let's do it!

Ross says that each blast
of the cold will help tame my reactions.

And here’s another kind of Arctic torture.

-We're going.
-Let's go.

We're going.

My brothers and I,
we love a bit of pointless competition.

So, we’re going all in.

-All right, let's go, fellas.
-Let's do it.

Go, get him. Where's he going with it?

I’ve got to keep using my muscles
in the cold...

...and maintain that coordination.

Oh!

Or try to, anyway.

And according to Ross,
repeating these doses...

should eventually break
the body’s resistance to the cold.

-Oh, boy.
-How do we feel, boys?

-I feel...

-I feel actually...
-I felt like I was gonna vomit.

-For me, it’s like absolute agony.
-Yeah. Yeah.

Does training for this actually
make any difference?

Well, it's... I don't know
if it's any less uncomfortable

or you're just more familiar
with being uncomfortable,

and I feel like definitely having done it

-a few times, you're like, "Okay..."
-Yeah.

-"...this is what it is." But...
-Yeah.

...I don't know that
there's a massive change in my body

because it's still
pretty uncomfortable, but...

-Yeah.
-Still pretty incredible.

-Yeah.
-It's... Thanks.

Yeah, I think doing things that hurt,
there's a benefit, right?

There's doing things that test you,
doing things that...

-Yeah.
-...are hard.

You know? Really pushing beyond
the boundaries of what you think

-is possible. And that really is...
-Yeah. And also a mental thing

when you have to reeducate your mind,
you have to change your mind to be like,

"No. I just need to find a way
to get through it."

Yeah.

You know, keep moving
and don't sort of let things fall apart.

Yeah. You wanna get every opportunity
possible to live a longer,

-healthier, happier life. And...
-Yeah.

And also not just living longer,
but living longer and strong.

Especially having kids, you wanna
be able to play with the grandchildren

-and still be active and...
-Yeah.

...and run down in the snow,
and jump in the ocean. You know?

-The emotional strength that comes...
-Yeah, there's a real sense of achievement

-from doing that too.
-Yeah.

Just the reward from actually run through
the snow and diving into this...

-Yeah.
-...you know, three degrees water...

-I think it also... It's... Yeah.
-...and running back again.

And I do think there's something
to what Ross is saying about just...

We've just become
far too comfortable in everything...

-Yeah.
-...the temperature of our house,

-our clothing. We're not used to...
-Yeah.

...any discomfort.
And that initial handbrake is really

an emotional response
of your body trying to preserve itself.

You know, whereas actually the body
has a whole lot more in the tank...

-Yeah. Yeah.
-...and you just gotta get past that.

I guess it’s easy to talk
about embracing the cold

when you’re sitting in a hot tub.

In reality, this swim is gonna take
it to another level.

And if I’m honest,
it’s a pretty daunting prospect.

But for one community in Japan,
the fact that the cold is daunting

is the whole point and leads to benefits
that go beyond the physical.

MR. SHINBO:
Entering the mountains

you can test your capacity
for all kinds of suffering.

Becoming
a Shugendo monk takes years of training.

For some, it's a fresh start.

Like Mr. Shinbo, who joined the order
after the death of his wife.

I couldn’t see the point in life anymore.

I was in great distress.

Then I encountered the Shugendo.

Today,
for the very first time,

Mr. Shinbo faces a truly terrifying test.

The waterfall.

Fresh from the snowfields
upstream, this torrent of meltwater

is so cold it can cause heart failure.

To pass, he needs to withstand
this freezing cascade...

-until his master is satisfied.

MR. SHINBO:
The effect of the cold water...

is like an electric shock.

MR. SHINBO: Putting yourself in a place
where you feel fear.

That’s the test.

MR. SHINBO:
There’s a story about baby eels.

If you add a predator
like a catfish to the tank...

they say more
of the young eels will survive.

MR. SHINBO: Humans also excel
in the face of adversity.

That’s what we’re trying to achieve.

MR. SHINBO:
I have experienced huge trauma,

but through these tests,
I’ve come to terms with the past.

If I met my younger self, I’d say,

"It’s going to be all right."

Even if you endure suffering,

you’re going to be all right.

I know
extreme temperatures could help

combat physical decline.

But during a long life, there are bound
to be mental challenges too.

The Shugendo rituals show
that confronting fear

and enduring the cold can build
a stronger mindset.

To do it with such focus and such grace...

that’s truly inspiring.

-What happens if you don’t make it?
-You’re gonna be there to fish me out!

-Although, I’m not getting in.

You know, it’s snowing
right now, too?

It is snowing, yeah.

-Oh, good luck with that.
-Thanks.

-Exhilarating.
-Yeah. Hmm.

Yeah, I think I’ve lost my mind.

-Yeah.

My challenge is to reach that buoy.

Two-hundred and fifty yards in water close
to freezing.

But I know why I’m here.

Enduring extreme conditions could help me
fight inflammaging,

manage pain and boost my immune system.

It can trigger repairs inside my cells,
and even improve my mental wellbeing.

So, it’s time to step up,

and just get this thing done.

-ROSS: Here we are.

And I have got to admit, I'm nervous,
because despite all the training,

this is now uncharted territory...

and so much could go wrong.

-Hey, boys. How are ya?
-Hi, Andy, safety team doctor.

-I see, yeah. Hey, mate.
-How you doing? I'm Tom.

-Hi, Ross. How are you?
-Andy, how are we, mate, we good?

-You good?
-Hey, mate, you all right?

Oh, yeah!

So, when you’re swimming, you’re gonna
have a tow-float tied to you.

And so, any issues, you can obviously
just grab that and hold that.

Do we have to have that or to... What?

Yeah, I mean... And especially
on ice swimming as well.

It just means if something goes
completely wrong and you go under,

-you’re still attached to it...
-Yeah.

...so we can then find you,
we grab the float.

Obviously, it’ll be a lot harder
than anything you’ve done so far

and your muscles are gonna get very stiff,
cold, and you'll become uncoordinated.

And when you get out of the water,
we don’t want you to warm up too fast,

because your limbs are gonna have lots
of cold blood in,

and if that all disappears back
to your heart quickly,

that can cause significant problems.

So, we need to warm you up slowly
and gradually.

Please make no mistakes.
It's a brutal swim.

You’re gonna be gasping for air
into a headwind.

It’s literally coming straight down
the barrel.

-Hmm.
-So, you’re gonna be pushing off there,

gasp reflex, going,

"Oh, good God, what’s going on?"
So, if all of a sudden if I say,

"Now, you’re coming out." Believe us.
It'll be for your own safety.

If you overegg this, if you push yourself
beyond the point

at which you should be coming out,
there is a real risk you could die.

Yep.

-From here. Yeah.
-Here? Right.

That's where we switch it on now,
okay?

I mean, even having
all these things in place

and having the people around.

I'm really nervous.

There is a whole lot of weather
coming

and, you know, it’s quite choppy
and windy.

It's absolutely freezing cold.

You know, the reality
is really kicking in.

Two minutes. Two minutes!

I just want controlled
and calm aggression.

So, when you go in, you’re just
so confident in every single one

of your strokes.
Overcoming that gasp reflex.

There you go, there you go.
There you go, there you go, there you go.

Let’s go. Come on!

-Yeah, mate.
-Yes, Chris.

The weather is getting worse
by the second.

Yeah.

Yeah. That wind just picked up
another ten knots.

-Yes! It's getting wild.
-It literally is.

My brothers are there.
They’re cheering me on.

So, I kinda got to do it.

Getting quite nervous now actually.

-Heart rate's definitely coming up.
-Suspense... is terrifying.

CHRIS: But the biggest motivation
of all...

is that this isn’t a battle
against the cold...

it’s a chance to fight back against death
and disease.

A battle against what time can do to me.

Focus on your breathing
and your physiology will follow!

Here he goes!

That instant shock
is just so intense.

It’s far colder than anything
that’s gone before.

All I’m thinking is, "Get this over with
as quickly as possible."

And I just take off.

-Almost there, mate!
-Go on, Christo!

Come on, mate!

He’s doing really well.
He’s keeping a good pace.

-Yeah.
-Ah, he’s killing it.

But after ten strokes,

it burns, it hurts. My head's thumping.

My body is screaming, "This is crazy.
What are you doing?"

Good, Chris. Let's go! Let's go! Breathe!

Come on! One arm after the other.
Just focus on that.

One arm after the other.

And then the worst
ice cream headache starts kicking in,

and I’m starting to really feel the cold.

-He’s slowing down.
-Oh, no!

Oh, come on, keep going.

CHRIS: Then all of a sudden, my arms
and legs feel like lead balloons.

I’m completely off in my balance.
And I just feel paralyzed.

Chris, come on! Stay with me. Focus!

There's sort of two voices
that were very intense and loud.

One was just saying to me,
"You’re gonna die."

-Let’s go, mate!
-Come on.

But the other voice is saying...

-"No way!"
-Come on, Chris. Go!

And all of a sudden, you discover
different parts of yourself.

CHRIS: So, I block everything else out
and I'm telling myself...

"Just get out of here."

Nice, nice! Let's go, big man. Let's go!

-Go! Go! Head down!
-Yeah, mate! Head down!

-Oh, that's the spirit!

Mind over matter. Mind over matter.
Turn it into a fight.

Last ten. Last ten! Finish this. Finish!

-Yes! Yes!

-Yes, big guy!

Yes! Yes! Yes! Yes! You are an animal.

-Yes, Christo!
-Yeah, boy!

-Yeah, yeah. Up you come, mate. Well done.

Get here, get here, get here, get here,
get here, get here, get here, get here.

Wrap it round so we can--
Turn around, turn around.

-Oh, I'm so dizzy.
-Get in, get in.

Yeah, we got gloves?
Have we got some gloves?

Get down, get down. Come on.
Sit there, sit there.

-Sit there, sit there, sit there,

sit there, sit there, sit there.

I’ve never felt like that before,
physically and emotionally so challenging

in such a short, concentrated period
of time.

-Yes! Yes!

And it’s an experience that will stay
with me forever.

You did absolutely everything
that I told you to do.

You did it, and then some.

CHRIS: And it did make me think
how comfortable

we’ve all become, in this day and age,

and that we’re far more capable
of doing things

that we think are impossible.

Chris, the cameras weren’t rolling.
We need one more take, mate.

-I am never doing that again!

-We forgot to load the film.

You know, we have an opportunity
to live longer, better.

Group hug, group hug!

-Yeah!
-You made it!

Challenging my body
with extreme temperatures...

could help me get there.

-They’re gonna defrost me now.
-Yeah.

-Yeah.
-Yeah.

CHRIS: I know my body can cope with it,

and I am confident it's working
its magic deep within my cells.

We'll see you in the Caribbean.

-I’m wintered. I’m wintered. I'm adapted.
-Fully wintered.

-You're fully wintered. Yes!

-What a time.
-Good job, mate.

-What a time to be alive.
-Yeah, boy.

And the cold never bothered me anyway.

Oh, my God. There you go.
