I just started reading a book about twins, incidentally, and apparently left-handedness occurs more than twice as often in twins (in one twin -- the other is usually a righty) as it does among single babies? There's speculation that some left-handed people were one member of a twin-set in which the other fetus didn't survive -- something that apparently happens more than I, at least, ever considered.
The whole fetus-in-twin thing is just one more incredibly surreal outcome, apparently.
