If you want to make it to the top in sports, you need the talent, which in this case, means the right genes.
Usain Bolt will never beat Haile Gebrselassie in a marathon, no matter how much training (or doping), and vice versa.
I am asking honestly, not to be condescending.
Small differences in heredity can have drastic effects on mental limits. Those limits may not be as easy to see as height is, but they are real, nonetheless.
Either way, my point was that I felt you should ignore physical attributes not related to mental abilities when discussing talent. I think using them as examples of "talents" making a difference just confuses the issue.
