I was idly watching a YouTube travel vid, and noticed easily 80% or more of virtually everyone in the informal group was overweight, obese, or close to morbidly obese. I suppose that’s because the latter group doesn’t to on travel tours.
Also watch a lot of older vids. Nary a fatty to be seen. Where did all the fat people come from??
One biggie is the office work we do now. The Navy had an issue when they used to load coal into the ship to keep them powered. So they did studies and they needed to eat like 3000-4000 calories a day to maintain their weight.
Well then they went diesel and nuke and never changed the menu. THey all got fat. So they eventually changed the menu. But still I know a lot of fatties in the Navy.
