I also think, Pamela, the food industry can take a bow for much of the obesity. They have scientists employed to trick the mid, to make everything moreish, and super-tempting. That, I believe, is a crime.
Until recent times, I don't think I ever taught an obese child. Sure, there were children who were cuddly, not many, but some.
Now they are obese.
Obesity just wasn't a thing when I was a child.
