I was being sarcastic. My point was that there are higher proportions of women in those fields than in CS [0], and the reason why might be interesting, but it's definitely not because those fields are easier; I'm not going to engage in a pissing match about which are harder but I think it's safe to say they those fields are
just as hard as CS. (medicine is harder, for the reason you pointed out, however that just makes my point stronger, if there's actually more women in pre-med than CS. not sure if that's true and didn't have time to do the research)
Anyway, there's no need to be rude, we're in agreement.
