I do enjoy the comments I get and am grateful for them as I do learn a great deal from them.
My guess on tennis players and their tummies seems to be confirmed by several commenters, a tennis coach and a Spaniard who knows what Nadal eats. Their diets will shorten their careers and leave a competitive edge to someone who takes the next step toward fitness by abandoning outmoded and incorrect advice from fitness experts.
As to Barry Bonds, I do not know if he ever took steroids or if he unknowingly took them, thinking they may have been flax seed oil. He has never tested positive. Even though his “trainer” had a protocol that included steroids, he has said Barry was not on that. My main point is that you cannot see what his critics seem to see in his statistics.
Too many people are seeing patterns where there is only randomness. Humans do that. It may have been adaptive in the evolutionary environment, which though complex did not approach the complexity we confront now. This is really a failing; a failure to see randomness rather than pattern. Nassim Taleb has written a nice book on this called Fooled by Randomness. This whole home run thing is a problem of being fooled by randomness.
Barry may or may not have taken steroids. His increased mass is easily attainable by someone who trains for mass and speed without steroids. I weighed just a bit less than he at the age of 65, though I have recently gone for more power to weight in my body composition. The decline of other athletes that is cited as evidence of steroid use is illusory. Aaron did not decline by much either. And nobody among older players trained like Barry. Moreover, there is not a shred of evidence that steroids alter aging patterns.
Journalists have to sell papers. Ted Williams was excoriated in the Boston press, largely by a single sports writer who later told Ted that he had to sell papers. This is one of the greatest and most disciplined and moral players ever to play the game. So, ignore the journalists. What do they know or care about but to sell papers.
Thus, where do we go for the “truth”? What do you want for truth? You seldom will get it when things are as variable as home run hitting is. The truth is that we can’t see patterns in the data that confirm any belief and yet, if we are eager enough, we can see things that confirm any belief you want to have.
