[Perfect Stu]

I believe that number 1 is...closer to the truth. But I don't have any evidence to support my opinion. You see, I believe that there are sprinters (using your example) that train harder than, oh say Maurice Green or Michael Johnson. Maybe their legs aren't as long, or they're too tall, or too short, or maybe their muscles can't develop to as good of a condition as the top sprinters'. Just look at the 100m sprinters. How many of them are white? Does that mean that white people choose not to train as hard for sprinting as black people? I don't necessarily think so. The same goes for basketball. Shouldn't white people be as good in basketball as black people, if they practiced hard enough (if there were no "invisible walls")? I am pretty sure that no matter how hard some people try, they don't have the physical ability to be the best in the world at anything athletic. I think some people are born with a gift to do a certain thing better than anyone else. Whether it be sports, track and field, or even writing.

That's all for now.
