(Laughter) So realizing I couldn't catch swimming penguins, she'd get these other penguins and bring them slowly towards me, bobbing like this, and she'd let them go.

You see, it will swim forward when it's happy; it will swim backward when it's trying to get away from something like, you know, a toxic chemical.

It's probably, at my speed, at my age -- for anybody's speed at anybody's age -- going to take 60, maybe 70, hours of continuous swimming, never getting out on the boat.

And when I started in with the eight hours and the 10 hours and the 12 hours and the 14 hours and the 15 hours and the 24-hour swims, I knew I had it, because I was making it through these.

And this time, I don't like it, I didn't want to give into it, but there's a difference between a non-stop swim and a staged swim.

Now, dolphins are social mammals, so they love to play, and one of their favorite games is to drag seaweed, or sargassum in this case, around.

That I'll just sort of do some celestial navigation -- (Laughter) And carry a bowie knife in my mouth, and I'll hunt fish and skin them alive and eat them, and maybe drag a desalinization plant behind me for fresh water.

(Laughter) It means that three architects can dream about swimming in the East River of New York, and then raise nearly half a million dollars from a community that gathered around their cause, no one client anymore.

It's a rainy, stormy, windy day, and people are getting sick on the boat, and I'm sitting there wearing a wetsuit, and I'm looking out the window in pure terror thinking I'm about to swim to my death.

At the end of all this cell division, they turn into a swimming larva -- a little tiny blob of fat the size of a poppy seed, but with all of the sensory systems that we have.

So going along, there's giant sharks everywhere, there are pyrosomes, there are swimming holothurians, there's giant sponges, but I make everyone go down to these dead fossil areas and spend ages kind of shoveling around on the seafloor.

Now, believe it or not, swimming around sinkholes full of dead things and cave full of bat poop isn't the smartest thing you could be doing with your life, but YOLO.

In your career and personal life, in your relationships, and in your heart and soul, your backwards-swimming fish do you great harm.

Hiroshi Ishii and his group at the MIT Media Lab took a ping-pong table and placed a projector above it, and on the ping-pong table they projected an image of water with fish swimming in it.

Be it my first test as a marathon swimmer, when I decided to swim for 12 hours non-stop in a swimming pool or crossing the English Channel in 13 hours and 55 minutes.

I remember, at the age of 14, when I jumped into an ocean for the first time for a swim, and throughout this swim, the waves were picking me up and throwing me down, I saw the child in me, who enjoys such adventures.

Unusually for his time, Melville doesn’t shy away from the ugly side of this industry, even taking the whale’s perspective at one point, when he speculates on how terrifying the huge shadows of the ships must be to the creature swimming below.

And so I decided to walk up to Mt. Everest, the highest mountain on this earth, and go and do a symbolic swim underneath the summit of Mt. Everest.
