Well I know women are supposed to have this great pain threshold but I’ve never witnessed it. And don’t give me that childbirth crap, because none of the women I know ever gave birth naturally. My mother did, but she was hard-core and worked as hard as any man. Most people are wimps these days, but only the very weakest men I’ve met would moan over a broken arm like a woman with a rock in her shoe.
