I am convinced that prosperity is the killer
The number of severely obese people is quite large and is a function of prosperity. Obesity will save Social Security and medicare as people die off early
Actually, I live in a wealthy community ( on the poor side of town.). The really rich folk are not obese at all.
I was a large guy in a senior role in two large companies. Onei. telecom. Another in banking. The higher I rose in the company, the more comments I heard on my waistline. And I am not what most people would call obese—I was built like a 40 year old stevedore or linebacker.
In the city I see young people who are just grossly obese. It’s a nutrition thing, not an abundance thing.
