Why have we progressed SO far with special effects in films, yet we still can't make the basics realistic?

Hairy women are gross. Kinda like they don't show people, uh, "evacuating their bowels" when they die. How would you like that? Alone, stranded in the desert, guy's love of his life is all hairy, dies in his arms, and poops and pees her tattered dress. Sorta takes away from things, don't you think?
