I'm just fortunate to be part of that skinny society in the 80's and having seen it first hand.2 things:
1)I looked at some family pics from 1970 the other day, and old school events from my parents era..
Every woman on the pictures had the physique of a victoria secret model, not one had any weight on them if they were under 50.
2) I walked round my local town the other day in the UK, it was the most disgusting site Ive ever seen in my life, nearly everywoman including the younger ladies, had those huge fat pouches above their tooty.
What's even more depressing is walking on any beaches now adays. Anyone can hide things behind clothing but it's hard to hide your body in a swimsuit. Now that is truly a depressing site in the today's society.
