I read of several villages in India where the women had evolved the characteristic of being able to sleep while still being able to continue to fan themselves with a hand fan. Apparently it is not something that can be learned, or at least the assumption is that it took scores of generations for this practice to be possible, and that there is probably some genetic marker for it by now. But perhaps the researchers were exaggerating in order to help put forward some agenda concerning dynamic evolution, when really some degree of limited motor function can be developed which can continue from waking through to sleeping. However, it would probably take years to develop such a skill, and that is only if the researchers are wrong about their insistence that such a practice would require a genetic predisposition.
