North compared to South
Having driven through part of the south, (half at night, straight line, bad representation of the people) now living in a very different part of south, (So. Florida, which is very different culturally than the rest of the south) and having spent most of my life as a "damn Yankee", I can say that I have seen more overweight people up north. I'm not saying people down here seem healthier; I'm saying they aren't as overweight as a general whole from my observations.
Having said that, there are things the North makes up for this with: Higher overall education. People up there, in general, seem smarter and more adaptable to changing situations, and also a bit less snobby, overall. I don't know, maybe the harsher weather forces you to adjust outside of your little bubble of self-indulgence. This is not to say that there aren't snobs up there; I've met more than a few. It just seems like the general attitude regarding random people up there isn't as much of "I'm better than everyone just because".
Also, the North has a much more special place in my heart because they've got more microbreweries and wineries around. (Of course, I'm from the Finger Lakes region of NY, so that may have something to do with my perception of that.)
@ AC: Wow human beings are really ignorant:
Spring water: Water bottled out of town. Look up the location that the stuff she's drinking is bottled- in most cases, it's actually bottled either relatively locally, or it's bottled in the middle of a suburban area, rather than the rural, idyllic paradise that is conjured up by the name on the label.
