Oh... I'm not saying psychological sources of stress can't be a cause.
I am simply responding to the implication that this might "all be in our head".
“The vague report you mentioned also states massive physicological attacks on the body as a route cause, not simple normal things like going for a jog every day”
The level of stress probably just dictates how long it takes to go through the stages and crash. He stressed the rats enough that they went through the stages in a few days.
I took 35 years to get to the crash point! So it seems logical that the amount of time it takes is inversely proportional the the intensity of stress.
Not sure what is “vague” about the report. It is a article published in the Journal of Neurophyschiary specifically discussing the stress research of Hans Selye. The foundation of James Wilsons book, and also the work of Dr Eck.
Possibly the difference between us and people who seem to be able to get away with stress for years is from epigenetics and pre-natal cortisol exposure.
