Merely Human: We've long passed the point in sports where any top level competition that requires purely physical action (as opposed to learned skills) will be won by someone who is genetically predisposed to do well. Lance Armstrong's lungs can process oxygen more than twice as efficiently as the average human; An NFL lineman must be 300 plus pounds and run a sub 5 second forty yard dash; And basketball players, well, you can't learn height. Now there's the ultimate ultra-marthoner with the perfectly neutral stride who wants to run untold hundreds of miles. Freaks, I tell you; the lot of 'em. My only hope is technology (we can rebuild him -- faster, stronger, better).
