My guess is that once upon a time it gave babies something to cling onto. Hair is a good indicator of health. A woman whose hair is falling out might indicate that she has a parasitic infection or some other disease.
For this reason, men find women attractive with long hair. Evolution basically has programmed men to find women with long hair attractive. Some women look good with short hair, but IMO it often looks less feminine.
My wife shaved all her hair off once because she found long hair uncomfortable in the heat of summer. I begged her to let it grow back. It didn't look good with the shape of her face.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
