Right, though perhaps you missed the part about people who eat well and exercise daily and still have these problems. Like I said, a lot of the chronic diseases we see today are part of living longer. There's no question that poor lifestyles contribute. I never said they didn't. Just that it's not as simple as the simple minded would have you think.
No it's environment. The chronic diseases we see today are the results of unnatural environmental impact. O of the Razor disagrees with your argument from complexity. My great grandparents were simple people with simple lives they were not simple minded. Complex people with neurotic lives jammed into vast suburban synthetic zones all develope developement diseases.
