No but I have known some foxy redheads.
They must be a treat once you get all the lice out of their hair.
Interestingly, human lice suggest our ancesters largely evolved in hot climate over the last 400,000 years or so, which argues against heavy genetic input or even extensive contact with local HNS in cold Europe. As it happens, humans are host to two different species of lice, the head lice and the crotch lice. Genetic studies suggest the two species of lice diverged from each other around 400,000 years ago. Lice can only live either where there is hair, or there is reasonably tight fitting clothing, preferrably made of fur. The fact that there are two species of lice on the human body, each specializing in its own hairy area suggests not only that human ancesters lost enough of their body hair 400,000 years ago to force their parasites to retreat to the two dense tufts that they had remaining, but also they did not wear any sort of reasonable close fitting clothing that would act as a bridge for the lice between the head and the crotch. This suggest our lice, and by insinuation our direct ancesters, evolved mainly in Africa, and did not have very close contacts with dwellers of cold climate such as neanderthals where one would expect any one type of lice infestation to propogate over the entire body via clothing.
Either that or Neanderthals, destined never to stoop to christianity, were simply cleaner and lice free.
