Undisputed Scientific Observation

Professional athletes, retired or otherwise, are not good actors. Not in movies. Not in corn chip commercials. Not in community theater productions of Agatha Christie plays. They are not good actors. They are good runners or slam dunkers or putters or archers or bowlers or whatever the hell they are. They are not good actors. This is a boundary that should not be crossed. They are also, almost as a rule, not good autobiographers. And many of them can't carry a tune. Why aren't these boundaries being respected?
