There are plenty of ugly overweight women paired up with relatively attractive men where I am, but on balance I'd say the opposite configuration dominates, the old 'fat stubble-faced schlub with a hot wife' sitcom trope. There could be mitigating factors, like makeup or the fact that I'm straight and don't generally scrutinize other dudes too carefully, but I get the feeling that at least in the areas that haven't been totally swamped by the obesity epidemic, it's nonetheless considered more acceptable for the guy to let himself go way before his wife does. I look forward to reaping the harvest of healthy divorcees when I'm in my 40s and still in great shape with a little silver in my beard and at my temples. ;-)
