Imagine you are Alice, stepping through the looking glass. Suddenly everything is re versed. Doorknobs are on the wrong side of doors. The gearshift in your car is in the wrong place.
Twenty-five million Americans wake up every day in just such an awkward situation. They are the one in ten of us who are left-handed and must face the world designed for the right-handed majority.
Why we are left-or-right-handed remains one of the great unsolved mysteries of science. We know that nearly two out of three lefties are male and that left-handedness runs in families. According to one study, almost half the offspring of two left-handed parents will be lefthanded. The Scots-Irish family Kerr (from the Gaelic word for "left") produced so many left-handers that in 1470 the family built its castle’s spiral stairways with a reverse twist to favor left-handed swordsmen.
On the other hand, heredity alone cannot explain leffies. At least 84 percent of them are born of two right-handed parents. And in 12 percent of genetically identical twins, one will be right-handed, the other left.
Perhaps the greatest puzzle of all is not why some people are left-handed, but rather why so few are. So, scientists are trying to discover the truth of the matter, and they are beginning to gain insight into many ways left-handed differ from right-handed by considering how their brains work.
