Another correlation, very unusual and interesting, is that past infection with Toxoplasmosis (a parasite that grows in cat poop) increases the chances of becoming an entrepreneur by a factor of 1.27 to 2
> they discovered that those infected with the parasite Toxoplasma gondii were, on average, 29% more likely than others to have founded a start-up, 27% more likely to have founded multiple ventures, and more than twice as likely to have founded their businesses alone
Along with an increased risk of death via car accidents, having contracted Toxoplasmosis seems to precipitate risk seeking behaviors, similar to its intended evolutionary prerogative: the infection makes rats sexually aroused by the smell of cat urine, so they seek the smell, where cats are more likely to be around, are eaten by cats, and the cycle continues.
I'm just guessing, but I think you'll find an even stronger correlations from Toxoplasmosis to the lack of traditional family obligations, and also the latter to entrepreneurship.
