Mark Frauenfelder at Boing Boing posted a great video of Aimee Mullins, a former Paralympic record-setter and an activist for women and people with disabilities. There's a very interesting - and, for me, somewhat irritating - discussion about the video, so rather than post the video myself, I'll direct you there. I came to the discussion late, which is just as well, given my feelings about some of the comments.
Aimee Mullins: How my legs give me super-powers
Many thanks to James for sending me this. I interviewed Mullins when she was a up-and-coming teenage amputee track star, so I'm always interested in what she's up to.
