Swimming is probably the ultimate of burnout sports. It's ironic because millions of people who swim as their regular exercise love the meditation aspect of it; you don't wind up with any orthopedic injuries. But when you swim at a world class level for hours and hours - the loneness of the long distance runner.

I grew up in Florida, so you start swimming at the age of 1, really. By 10, I was competitive swimming, and by 12, I had aspirations to be the best in the world.
