That Alzheimer's memory loss story is pretty interesting.
For one patient the basic regiment was largely: better diet, exercise, less stress, more sleep, and weight loss. There was a drug too, but I still found the rest of it telling.
I've been thinking for some time now that some of our illnesses (and probably sociopathic behaviors) come from being chronically overworked, tired, poorly nourished, and under too much stress for too long of a period.
It's just a suspicion.
