BUT players skills diminish with age. It's a fact of life.
There was an all too recent time when some players seemed to buck this trend. Some guy named Bud claimed to have no clue as to why this was happening unlike any other time in MLB. Guys w/ names like Mark, Sammy, Barry, Rafeal, Luis (and others) made incredible adjustments w/ weightlifting and diets (right, Bud?) to buck that age-old trend of age diminishes skills.
