aThe only place I found "hirtellous" was in a glossary of botanical terms.
As far as Esau is concerned, I'd stick with the Biblical words. The psychological
reactions to hair are certainly peculiar. Why do I wish I had more on my scalp,
and less elsewhere? One patient I had a long time ago could not shave without
cumulative dermatology problems. So he used to spread a horrid smelling paste
of barium sulfide on his beard area, wait half an hour, and the hair would be so
soft, he could take it off with a table knife. But I'd rather do that than have a
beard. Incidentally, beards had to go, because soldiers got lice, and the brass
had to abolish beards and long hair. And the Gillette razor made it easy.
