Data are presented on the prevalence of current left-handedness and prior left-handedness (switched) in 2787 subjects from 21 to 101 years of age.
In addition, data on sex differences, familial sinistrality, hand posture when writing, and education were recorded.
Two hypotheses were tested.
The elimination hypothesis states that reduced frequency of left-handers in old age is due to reduced longevity.
The modification hypothesis states that differences in the number of left-handers between older and younger persons are due to changing patterns of social norms.
