How about a sting by one of these?

What if we told you that there are people out there who seek out this stuff?

Would you ever try them?

Well, you know the saying.

Never say never.

No, this is Justin Schmidt.

My name is Justin Schmidt.

He's an entomologist and I'm an entomologist.

I basically studies stinging insects.

He's been stung by a lot of insects.

I've probably been stung a t least 1000 times.

He reviews insect stings the way a Somalia reviews wine.

Pure, intense, brilliant pain.

Like walking over flaming charcoal with a three inch nail embedded in your heel.

Which insect was that?

That's the bullet ant.

This is his lab in Tucson.

This'll is his harvester ant.

This is his vinegar.

Rune.

This is his torrential A hawk.

These are some more harvester ants in a park near his lab.

He is the creator of the Schmidt Pain scale.

The Schmidt pain scale is basically a scale to rate the painful nous of stinging insects On a scale of 1 to 41 would be a sweat bee.

Two would be something like a yellow jacket.

Waas the three would be something like, Ah, Harvest Strand and a four would be a torrential OC.

How bad is it for?

For it's absolutely excruciating.

The debilitating incapacitating just shut you down.

Just absolute sheer pain.

There's just nothing you can really do about that.

I don't think I want to be stung by, Ah whole bunch of different fourth.

I don't think I could endure that for very long.

Let's be clear.

Justin Schmidt doesn't just go out and get stung on purpose.

It's just that he's dedicated his life to studying.

Well, my passion is insects and stinging insects in particular.

Yeah, I get stung.

But that Zall just part of the passion, you know that that gives me data.

You know, stink helps me and understanding what the insects doing, and I get to be out in the sunshine and out in the rain out in the environment, Study these magnificent, beautiful insects.

Just just such a joy.

I can't imagine anything.

I'd rather do more what highest you've ever slept that almost a while.

When you don't have a fear of heights, it's not really scary.

It's like being in the craziest house that you can possibly imagine That's marks in it.

He's a professional rock climber, and he's talking about sleeping in a tent.

They're called total edges that's hanging off the side of a mountain he's been climbing for over 30 years, and his favorite walls to climb are really, really high Alpine.

Big wall climbing is here pursuit of scaling the biggest cliffs on planet earth.

Oh, in here they take a few days to summit, so he has to camp out along the way.

So I want to know what does it feel like to sleep in a portal edge, hanging off the side of a mountain?

One thing that's more or less ever present in the mountains is when it can be pretty violent.

You can experience hurricane force winds.

There's also this thing that we call the Bronco ride.

Wind comes in, hits a cliff, and it really has nowhere to go except for up.

Eventually it hits you and your ledge.

It can lift the whole thing up so you could be suspended.

And then, of course, ledge like slams into the wall.

Your just thinking about surviving, and that wasn't the worst of it.

The smell on the ledges is not is not nice.

You don't change your clothes, you don't bathe.

It's wicked scummy, but people love it.

They continue to climb and explore through all of this punishment because there's still that one question left.

How does it feel?

The way it makes you feel is like a tiny speck of dust, Very empowering.

It really is just like kind of the most spectacular spot that you could be appointed Earth.

Oh, if you are uni cyclist, you see the world really, really different.

If our girls will city and I see a bench for me, it's not a bench.

Something we're seeing.

Can I jump on it?

So the world, it's an obstacle for me.

E.

I think this is too steep.

Is it possible to drop on this work?

So it really changed my perspective on everything.

My name is Liv specials.

I'm a professional mountain uni cyclist.

That means I unit cycle in the mountains.

I started unicycling at the age of nine.

First, I own Eunice, cycle it on the street, and over the years I got more and more extreme in our unit cycle, mostly in the mountains.

I really like to go down big mountains.

So I did a 5600 m mountain in Iran a couple of years ago, and I want to go on even higher mountains E u recycled on five continents.

So in many, many places in the world, it's the biggest challenge on a uni cyclist toe.

Always stay in balance.

Technically, the most important movement are my legs because I always have to pedal, so my legs are always moving.

Then my white arm I used to balance.

So I moved it up and down.

My left arm maintains the break.

If I go down on hard terrain, I'm not thinking at all.

I'm just in the moment.

I'm 100% focus just on the spot on the movement, because if I start to think for sure, I would fall down.

I like to do stuff which has not done by so many people, and I think it's a bigger challenge.

If you don't have people you can copy, and you have to invent a spot a little bit by yourself.

Civilian unique.

It's really special and testing.

That's a big part.

Why I like it so much.

Every waterway in the United States is supposed to be safe enough to swim in every single day.

But of course they're not.

I'm getting in to these contaminated water raising someone's gotta risk something.

If people see that image, they start to ask themselves, Why is that guy in there That starts a discussion that can lead to a clean up?

My name is Christopher Swain, and I've swum over 3000 miles in over 25 different contaminated waterways in North America.

I want to advocate for these waterways and I can energize cleanups.

E learned to swim as a kid.

I was the kid who didn't want to get out of the water, A Z.

I got older and I think this is true for many of us.

I started to become aware that water's air contaminated with everything from arsenic to zinc, everything from human waste to nuclear waste.

We saw our waterways as dumpsters.

We saw them as sewers, legally speaking, since 1972 when the federal Clean Water Act passed all navigable U.

S.

Waterways have to be safe for swimming and fishing and drinking.

If they're freshwater creek, dozens and dozens of those waterways were in and around New York City.

Newtown Creek is the worst of those.

It is contaminated with lots of things.

Heavy metals, toxic chemicals, raw sewage and one of the largest ongoing oil spills in the history of the United States.

So in some way, we stole this waterway from ourselves.

What I'm saying is, let's turn that around when I decide to take on a waterway.

This is my puncture resistant dry suit.

I take all these measures on all my swims to protect my body and to protect my health.

I wear a cap.

I wear goggles.

I wear earplugs.

I never put my head under.

Even so, I've gotten sick lots of times.

Rashes, skin infections, ear infections, respiratory infections.

It's a hazard that goes with the territory, a reason nobody has swum the length of Newtown Creek in history.

Is that a toll east?

In the last 100 years, it's been far too disgusting.

No one in their right mind would go in.

There s It's like swimming through a dirty diaper that's been garnished with oil, gasoline and trash.

Every part of your skin wants to crawl, so why do I push on and do it.

I'm doing this out of love like I really do love the water.

And I don't have a lot to work with.

I'm not a wealthy person.

I'm not a scientist.

What if God is my body and my life offer, I'm gonna keep going back in my dry suit and my hazmat gear until these waterways air clean and when they're clean, I'm gonna get into these clean waterways in my bathing suit and enjoy them with my fellow citizens.
