Agreed, and I am generalizing. But it's true that people in major cities tend to be healthier--whether it's walking more, exercising more, eating healthier, or a combo, I'm not claiming to know one way or another.
It's also the case that the majority of urban and metropolitan jobs are in business, finance, etc.
Clearly this is a vague and highly general argument, and I'm not taking the time to go find stats on all this because I'm drawing on previous knowledge from various sources about the increase in urban jobs and the health of urban residents. I'm really sorry guys, but I just don't have time to go and find all the stats and numbers. I know you guys like that, so I understand if you won't trust the claims due to lack of statistical evidence. Pointing out that I'm not providing these won't change my mind, since I recall what I've read in the past (many of these sources go back years, which is why I'm not jumping up to go find them).
I really don't intend this to be insulting or stand-offish, but I kind of figure that if anyone cares to investigate a particular comment that is said on this forum, then he or she will go do some research of their own. That's how I approach this entire platform. We all say controversial things, but when one of you does so I usually go and do a Google search of my own.
