Left-handedness and life expectancy.
Halpern and Coren recently described an association between left-handedness and a lower life expectancy. This finding is not unexpected because left-handedness has been linked to three leading causes of death in our society--alcoholism, smoking, and breast cancer--as well as to several neurological and immune disorders.
