While scuba diving off the British Virgin Islands about 25 years ago, our boat's anchor got stuck. I dived down to release it, but I got separated from the boat and was stranded as it sped away. I had to swim for an hour to the nearest island with all my scuba kit on before I was rescued.

I took up scuba diving, and my next big thing is BASE jumping.

MMA makes you sore and tired every day. I wonder what we're going to be like when we're 50 or 60. I wake up some mornings and just say, 'Oh, God.' And then I go scuba diving.

I love skiing, scuba diving and hang-gliding.

Successful technologies often begin as hobbies. Jacques Cousteau invented scuba diving because he enjoyed exploring caves. The Wright brothers invented flying as a relief from the monotony of their normal business of selling and repairing bicycles.

I enjoy challenging myself to try new things, going outdoors, scuba diving, running a marathon. Anything that I have never done before, I enjoy trying it out.

Growing up in Alaska, they don't really teach you to swim there. I learned to swim just a few summers ago with Olympic gold medalist Amanda Beard. She did great, and right after that I went to get scuba certified. I had fun with it. I didn't really get scared, but some people thought that was a risk.

Something I like to do a lot is just sit by water when there's a current and just stare into the water. I don't fish, I don't hunt, I don't scuba, I don't spear, don't boat, don't play basketball or football - I excel at staring into space. I'm really good at that.
