A separate analysis for males and females also revealed a 14-year difference in age of death, as men are more likely to be left-handed than women (9, 1% versus 5.8%, Marcel E. Salive, MD, MPH, and Jack M. Gurlnik, MD, PhD). With this result, it became doubtful whether differential mortality could explain the distribution of handedness in the population; a previous report stating that left-handed people were at increased risk of nonfatal injuries did not have follow-up mortality by laterality. The simulation of the previous study assumed no difference in mortality between left-handed and right-handed people, the relative lack of left-handed people at older ages explains the reported lower average age at death for all left-handed decedents compared to that of right-handed decedents. However the main factor was that a lower average age at death in left-handed people does not imply anything regarding their risk of death (Halpern and Coren data). Although left-handed people belong to a younger age population, and it is known that a greater percentage of deaths at younger ages are due to injuries
