"I'm not running around as a continual ray of sunshine. It's just I don't believe in wasting time fee..." — Aimee Mullins

My varying pairs of legs can be quite practical or quite impractical, and I don't judge them either way. Some are for getting around a 12-hour day, pounding the pavement, and some are to feel like I can transform my own body into a workable, changing piece of art.

A couple of years ago, I had my DNA sequencing done, and it is all anonymous. When the results came back, my musculature type said, 'most likely to be a sprinter.'

'Triumph over tragedy' - how pathetic! I think people are generally freaked out that I'm multifaceted. You don't hear people saying, 'Gwyneth Paltrow won an Oscar - and she's blonde!'

I didn't see how wearing prosthetics was quite so different from being born with flaming red hair in a crowd of black-haired babies, or being of a different religion from that of every other child in your area.
