re: Is your S/O fat? Would you ever tell him/her to get in better shape?

Men are hardwired to be attracted to young women with a certain hip/waist ratio because men are genetically programmed to engage in reproductive behavior. Old women have lost their ability to have babies. Obese women are subconscoiusly written of as either unhealthy i.e. not being able to produce healthy offspring, or as being pregnant.
