Body language
Do you place an invisible asterisk next to your respect for athletes who are able to excel at the highest level in part because of a genetic gift such as unusual height, being a pixie or whatever?
(I'm not suggesting that these attributes alone make top athletes special. Not for a second. But where training and talent could make someone a great soccer player or baseball shortstop, practice alone won't equip someone to be an NBA forward or NFL tackle if he doesn't have the right body type.)
