Here's my guess:
* people eat shit
* people don't exercise, not even a little, like walking a couple of miles
* doctors are too eager to medicalise everything so that they can put you on drugs

Not so for mental health. Without any incentive to diagnose perfect health and without any way to mechanically prove health, doctors are bound to have a bias for false positives.
I am not saying that the doctors are at fault. But doctors are rewarded for finding illnesses, not curing them. Sad.
Having decent resources, but expectations that you will put those resources to work, and being fed conflicting values as to what success actually means (as well has how to achieve it) can send you; well; crazy.
