I threw the javelin in high school, but that's only part of the reason for my good arm. I got my good arm from my mother. Today she's 73, yet she can throw a ball from second base to home plate with something on it. Last year, when they opened the amateur winter league in Puerto Rico, she threw out the first ball from a box seat to home plate. She had something on it, too. She's in good health.
