Does this include people who grew up vegetarian? I suspect people who are vegetarian for cultural reasons (e.g. myself) would have a much lower chance of "returning" to Meat (don't know if I would even call it returning) than those who initially ate meat, became vegetarians, and then went back to eating meat. Also surprised that only 2% of Americans are vegetarian, but probably because I've lived in California most of my life.. I also wonder what percent of Americans eat meat 1 or more days / week, 2 days / week, etc..
