I believe, that if what they are saying is true, then taken into consideration with what we know about American diet, Americans would seem to be devolving into fat, incompetant, lazy slobs, who are highly disease prone.
Maybe this explains a good deal of the decline of America.
Maybe the McDonaldization of America is literally the root cause of most of the incompetance, bad behavior and cultural decay that America seems to be suffering from.

NOTE: On a plus side, this means that you can possibly tinker with your own epigenome very easily, so that if you were born with not so good qualities, you can modify yourself so that your offspring will have tremendously good qualities. That's my plan anyways!
