Yeah, you see any videos, or photos of back in the 70's, and you don't see fat people. One that comes to mind is a video of Skynyrd playing Freebird at the Oakland Colisium in 77. The people in the crowd are shown often, and you can't find a fat person amoung thousands of people. I remember in school, it was rarity if a kid was fat. Now I see all these young kids and many of them are just not over weight, but obese. Its really sad. Most of it is from eating junk food, and inactivity. I remember the day when I could drive through the community I live near, and there were always kids on the ball field or outside playing. Now. I never see any kids on the ball field, and I do mean never.
America has grown fat, and lazy. Very few what to get into a trade where there might be some physical work involved. They all want a job sitting at a desk. When I was a kid my mom wouldn't let us sit around in the house. We were always outside working the garden, push mowing our rather large yard, working at the farm, riding bikes or playing a sport. One of my mom's sayings was. "Get outside and get the stink blown off you". What you do as a child does become a life style for life.
