And well said, after lunching for many years with 3 very overweight colleagues, I could see that they empowered each other to ignore their weight as a health issue. One routine that sticks out in my mind vividly is the daily game of "oh, I should have a second dish of ice cream..." and the "oh go ahead, it's only this once."
I think it is the freakonomics guy that found a link between the weight of friends of friends and your future weight, so great is the influence. For example, collegues of DW cook things for her and that stuff is brought home, and hoovered by yours truely upon sight
reminds me of a similar Antony Robbins idea, that you future income will approach the average income of those you association with.
