Left-handed women may have a shorter life-span.
I'll take what comfort I can in the words of my fellow left-hander who is quoted in the article:
The author of a commentary, Dr. Olga Basso, who is left-handed, is highly skeptical, in general, of research relating disease and death with handedness. "I am not alone in thinking that the literature on handedness suffers from a number of ills," regardless of the putative illnesses seen in those who are left-handed, she notes.
"Having successfully dodged a number of disorders," adds Basso, "I doubt that my left hand is prematurely pulling me toward my grave."
Basso is with National Institute of Environmental Health Sciences, Research Triangle Park, North Carolina.
