Biological evolution is no more a deciding factor when discussing
civilized life. Siestaring is like language, one's got to be born into
the culture; late learning isn't very likely to be perfect. The study
wasn't at all designed and balanced for that. Missing the noon nap and
the late night life definitely shortens life if you're a born siester.
Watch for my obit.
