As for Tara's career ending injury, well... Michelle had one, too. Injuries are part of sports, and, in skating, nasty ones can happen doing doubles or having a freak fall out of a flying camel.
Michelle sustained her career ending injury as an adult. Tara OTOH had a career ending injuury at an age when she was too young to consent to medical treatment ... but IIRC she didn't begin to practice her triple loop combos until she was at least at the senior national level. Both of these are quite different than her recommendation that "young skaters" take more risks. That injuries can happen in any sport doesn't alter the fact that when the participants are young, you don't encourage the kids to increase the inherent danger!
