> If I'm sitting there hacking out a weird new concept for accessing databases and my wife comes into the room and wants to talk about our son's baseball game, I put down the text editor and listen to my wife
Sounds like you have a wife that doesn't respect your hacking time to me.
I wasn't saying that I do or that anyone ought to accept obesity as normal. However, in my country (I'm an American) it is prevalent. I'm overweight (though not obese) too. It's not that weird to view it as typical. The word "norm" can be construed in a lot of ways. In one sense it just means typical or average or median. In another sense it means normative or preferred. I think we know what sense of the word we're dealing with here though.
