I am probably way off here, but I can't help but see this thread as being intended to be a bit of a gloat fest. It isn't like anyone who is actually obese is going to want to admit it to everyone, especially when the OP says he assumes probably 60-70% of us are overweight but makes certain to announce he isn't one of them.
That's not my intention. As I remarked, about 50% of our peers are overweight as it is. Think of it like smoking, except that instead of causing lung cancer it causes heart disease.
I hardley think the two different size peoples of the forum are going to start having it out with each other. Better if u want to discuss it :) after all it probably isn't a topic of general conversation with your friends!
