Los Angeles
In February 1991, I was rushed to the hospital in Los Angeles to have my feet amputated. Three years earlier, I had broken the national 100 meters hurdles record while a student at UCLA and was a favourite for the event at the 1988 Seoul Olympics.
Tip the world over on its side and everything loose will land in Los Angeles.
In Los Angeles, I drive a hybrid and live in a very simple home. Anything you do from carrying a canteen of water to starting a recycling program in your office makes a difference. Reusing what you already have has always been green - from clothes to boxes to glass jars from the supermarket.
When I turned 11, my dad decorated a room at the Standard hotel in Los Angeles in a '60s, Austin Powers style. There was human bowling: You run inside a giant inflatable ball and try to knock down pins. To this day, adults say it was one of the craziest parties they've ever been to.
