There's definitely more obesity over here now than in "my day"... but, on the whole, in the cities at least, most seem slim to me.
In the country, in my village at least, people are older and rounder but not obese. They're busy people, hard working too, so sitting around eating isn't something they do...
I just reread what I wrote. Am I saying that overweight people aren't busy or hard working? I certainly used to spend a lot of time on my butt eating! (Still do, mind, just different things!)
