"There is much evidence that the female is constitutionally stronger than the male; she lives longer, and in every age group more males than females die although the number of males conceived may be between ten and thirty per cent more. There is no explanation for the more frequent conception of males, for female producing spermatozoa are produced in the same number as male producing ones. It is tempting to speculate whether this might not be a natural compensation for the greater vulnerability of males"
