Performance and handedness data were examined for 3,647 professional basketball players who participated in at least five games during the period between 1946 and 2009. Left-handed players comprised 5.1% of all professional basketball players compared to the 11% prevalence in the general population. Left-handers had better performance averages, in terms of the number of points, rebounds, and blocks over their careers, as well as other measures, and had significantly longer careers than right-handed players. Handedness was not significantly related to mean or median life expectancy.
