Mickey Rourke doesn’t look like he is all that fastidious to me. I’d want to do some boiling of my own.
Men get the benefit of aging and having "character" women keep pulling the forehead up and shooting the botox. Joan River's face is so tight, whenever she sneezes she has an orgasm.
It is possible however that whatever they have individually swimming around in their bloodstreams would either completely neutralize the others' diseases and become an "uber-innoculation" for every STD on earth (human or zoologically vectored), or more likely would just combine and mutate to incubate a mega-virus that would kill us all in a week.
Either that, or they'll beat the odds, produce a beautiful kid, and then name it something inane like "Solar Sunflower" or "Polar Bear".
