Left-handed major-league baseball players and longevity re-examined.

We re-examined the relationship between handedness and age at death for major league baseball players who died before 2002. This study extended the most recent examination of this issue by 13 years allowing us to compare 870 left-handers, 4,092 right-handers, and 1,092 bimanual players. Our study also took into account year of birth and player's position, both of which are related to longevity. Our analysis yielded no significant differences in longevity related to handedness (F(2,6035) = 0.13).
