Why do old ladies smell so bad?

Answer 1

Mmm not ALL women smell bad, to you personally. See, how much you like a woman's natural smell depends on the compatibility of your immune systems. It's for "mating", you could say. The two mates need to have very different immune system to provide the child with the most diverse and covered system possible. For example, your sister should smell disgusting to you, because your immune systems are very alike. :)
