A separate analysis for men and women also found 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, differential mortality as an explanation for the distribution of hand in the population became doubtful; a previous report that left-handers are at higher risk of nonfatal injuries did not track mortality by handedness. The simulation from the previous study assumed that there was no difference in mortality between left-handers and right-handers, the relative lack of left-handers at the highest ages explains the lower average age at death for all left-handed deceased by compared to that of the deceased right-handed people. However, the main factor was that a lower average age at death among left-handers did not imply anything related to their risk of death (Halpern and Coren data). Although left-handers constitute a younger population, it is well established that a greater proportion of deaths at younger ages are due to injuries.
