I just played that (with the sound down, as I'm having my coffee and listening to jazz this am..) It's damn spooky, that looked like my childhood.. period.
While I agree that not EVERYONE got MO, SMO, or SSMO from eating junk.. I do still believe that the vast, vast majority did not gain to the size of needing medical intervention on meat, veggies, fats, and occasional healthy carbs.. aka real food in normal amounts. To dismiss that reality is at least for me akin to giving up my own power over my actions and choices that I made. I refuse to deny what made me obese, I ate too much, and waaay too much of the wrong shit too often.. I am not saying that my reality is anothers, but I am also saying I think mine is more common than rare among the MO set.
