Supple Cow, if you had taken the time to think about what I posted, you would find that it was supportive of both your and safronlove's posts. It points out that the "poor correlation" isn't a nebulous "fat/poor connection" but real factors that are likely affecting that group (eg. specific activities, state of mind, etc.) At the same time, it illustrates that the being poor "cause and effect" isn't necessarily true because the poor aren't the only ones who have these issues.
So, no, it doesn't end the thread but puts it into perspective: what is it about the poor that contributes to their weight issues? How does this differ from the other classes? What can be done? etc, etc.
[Nice tone, by the way. Well played. Was that retaining water pun intentional or no?
