I haven't generalized anything beyond the extents of

1. my area geographically
2. The groups in my area which i interact with
3. An individuals weight within a community over time.

I have not said it's impossible to do for me and have made no claim on the ability for others to do it.

I'll give you so much as i didn't append "for me" or "in my situation" to every sentence, but the statements lay within the context provided in the rest of the post.
