It's also evidence of why he can medal in more than a half-doz events -- his sport is not as physically challenging as others where even two medals is a super-human achievement.
The single toughest event in all of sport is the 100m.It has the greatest talent pool going in (all kids run, but not all play soccer, and relatively few ever compete w/ a barbell or in a pool).Your point about the variety of events is good, and one of my main gripes about how our sport could be improved to give the best athletes more chances to succeed and magnify their success.My main point is that their are NO OTHER Olympic sports where it's even possible to get so many medals, and the primary reason is that the recovery from swimming is so much easier. MP swam multiple heats and finals per day, and other sports are just too demanding to allow for that.Swimming seems to still be remarkably early in it's performance curve, and so records fall more readily, and talent gets an even bigger boost from hard work.
