I don't know anybody these days who's got one, but in high school I knew two students who'd each lost a leg and had a prosthetis. Both walked with an odd gait.
Both were white middle-class kids who became high over-achievers, leaders in student government, president of the clubs, etc. We joked that nobody with two legs had a shot.
As an adult looking back, I'm sure they were both compensating for the loss, even overcompensating. I lost track of the girl, but the guy did okay in college but became an increasingly bitter adult, fairly reclusive, and angry with the world. I've attempted to find him online, but there's nothing. I have wondered if he might have killed himself.
BTW, the guy was quite the ladies' man in certain circles, and the girl was uber-pure. I'm sure body image issues affected them both.
Maryn, knowing people with more recent info will arrive soon
