Marvelous, as always. It's not often that one'd see such high-quality translations. Makes sense since the manga is so top-notch. Probably one the most well-drawn I've seen. The artist is clearly talented.

One of the most important points is probably that women are more resistant to pain on a physiological level (see: childbirth) and to long-term psychological stress. They cope with the letter, though, by being more prone to panics and having less control over their psyche (in other words, they build up less long-term stress since they pump it out much more often and easier).
So yea, that idea has some actual basis. Though it's not hard to argue it either, since it has obvious cons too.
