???Exercise??? is mindset as well as activity Neuroanthropology writes: “Becoming convinced that they were getting enough exercise or engaged in adequate activity to promote health helped their background activity to affect their physiology. Exercise was not just a physical activity, it was also a state of mind (more accurately, without the ???state of mind??? activity didn???t have the effects of ???exercise???”
of course they WERE getting sufficient exercise, but the really interesting thing here is how they didn’t BENEFIT from that exercise until they were made aware that it WAS sufficient, and then how very quickly the physical results were manifest.
