there are degrees, and i never said otherwise. What i ment by "anthropomorphic equvalent of a truck" is exactly what you described - pathological consumers with a very unhealthy diet. I guess i have chosen my words poorly, therefore made my thought unclear. There are lots of fat people that are quite strong, and this is ok to me, as i said.

The part about physical activity wasn't exactly about fat people though, rather about our modern society in general. A healthy diet with the correct balance, and moderate physical activity makes wonders, not simply in terms of weight. Those two things are grately underestimated. Those things were underestimated by me. After i started to be more physically active, my thoughts got clearer and i became much happier in general. And yeah, the best gym is a part-time job in a field, if you ask me. Actual gym sucks compared to it.

Unless the obese are a hitherto untapped source of entropy-defying free energy, your statements cannot be correct.
