most americans are just big people,,,both males and females,,,its as simple as that (irish,,scotish,,etc)
when you have big/thick people,, frame wize/bone wize,,,and you combine it with good ole whole milk, ham and pizza hut plus some macs and good ole sonnys,,,you create a belief in the american female's head that the average guy is 220lb,,and that makes her think that being 180lb makes her look good.....
the coutry is severly obese. if you gotta work out at 5'7 to maintain yourself at 240lb insted of 260lb ,,,you my friend are obese.
