We go to lots of high schools for blood drives, and it almost makes me cry to see all the flabby teens that are from fat to very obese. Most of them are not up to Morbidly Obese, but a little past the very obese, and even the males are developing breasts. What is frightening about this is watching small children in the summer time when they are wearing tight tee shirts. Lots of them from 6 to 9 years old are also developing breasts, males as well as females, from the hormones most of the companies claim is not in their meat.
Looking back on many of my old pictures of family and friends, (I'm 77 now) I can only see a very few that were overweight, and most of them were crippled. Others all walked and ran, played outdoors all the time the weather let them, and ate slow food at home. Going "Out to eat" was a treat that was as lovely as it was rare, and kids ate what was put in front of them without whining. Or else at home they could sit and stare at the food until they did like it. There was no junk food around all the time then.
I quite easily remember toting a lard pail to school with my lunch in it. It usually was a sandwich with a biscuit and some kind of meat from the farm and a lot of mustard, an apple or home made cookies and sometimes a pint of buttermilk.
