What kind of ants are we talking about here, because I cannot imagine anything good from doing this with a fire ant mound.

This doesn't seem realistic.

Men, most who don't wear cosmetics, don't spontaneously stick their faces against ant hills. The women who don't wear cosmetics, either, don't seem to cover their faces in ants.

Crows (and other animals) are known to learn behaviors from each other, it doesn't need to be genetically encoded

I was answering this comment, "Before cosmetics were available, some people stuck their face to an ants nest, I think the theory was that that could help peeling dead skin," which was not about crow's behaviour - either by nurture or nature.

I can't believe that people are actually taking that comment from the parent seriously. All I can say is that people tend to believe whatever they read.

Yeah I read that, but I take your point. I'm open minded to it, there's an assortment of weird remedies and therapies that humans have engaged in. People are so obsessed with their own appearance and go to great lengths to improve it... I mean people stick their feet in ponds and let fish eat all the dead skin off to exfoliate their feet.. this is something you can pay money for in a number of tourist cities.
