What is the key lesson to be learned from Clemens II? The obvious one is certainly, do not use performance enhancing drugs. The broader lessen for us non-superstar athletes is an old saw: the punishment for lying is worse than the crime itself.
Down in the hard wiring and chemistry of the brain's survival instincts, if you show someone a picture of Roger Clemens and talk about the charges that he lied, it's like showing them a picture of a snake.
Clemens acted as if he could bully Congress the way he could intimidate hitters with fastballs. But perhaps the public revulsion toward cheaters and liars will help to make him the fall guy for a tainted era.
