Scientists in the UK have surveyed thousand of females of all shapes and sizes and have discovered those with "big bums, thighs and hips are the healthiest.
It has something to do with that hip, bum and thigh fat is harder to break down thus the releasing of harmful cykotones into the body is less than for example, belly fat.
So beer-gutted women are naturally unhealthier than their counterparts with huge posteriors, elephant thighs and ginormous sex-handles around their waists.
Women hoping to get rid of their fatty bums, etc, have been told to keep them and those with enormous beer-guts told to let them sink further down.
As for males, scientists have also proven that having a ginormous beer-gut is also unhealthy, gets in the way of hot-sex, except whilst "doggying-it" and continually wobbles whilst feebly attempting to jog it off causing heart tremors.(you can't win can you?)
Scientists recommend that men should switch to wine, have lots of sex with fatty bummed, etc, females so they can both grow old "bonking grandly"!
As for "Skinnies" Scientists are researching copulating "stick insects" hoping they can discover a remedy for "bone chipping during penetrations" OUCH!
