Well, it's pretty hard to know what to make of this kind of thing, but I thought
this was interesting:

It's a report on a study which suggests that men who have higher levels of
estrogen are better at science than those who have lower levels. Which doesn't
explain why women, having usually higher levels of estrogen than men, are
under-represented in hard science, programming etc.
Also it doesn't explain why my ring finger is longer than my index finger, which
apparently should make me be into the social sciences, not this debian stuff ;)
