He is using a different method of propulsion? It looks more like running than, for instance, using a wheelchair does, but looks can be deceiving and it's still fairly transparently different?
I definitely don't get the A qualification time part of it all, because wheelchair athletes are way faster than the able bodied from 800m onwards....so how come they aren't competing in the olympics as well as the paralympics in 2012? presumably because they would actually win
And while I'm on the topic, how come there is a separate event in high jump for women and men but not for short and tall? Or in other words why are women given a special dispensation for being slightly less good at high jump but short people aren't?
