I understand your point, while not detracting from the benefits of exercise, eating well, having moments of calm, etc,etc, these studies when reduced to a personal level become nonsensical, while one can make choices that at a 'group' level might suggest cause and effect, when the sample size is one, and it's you, the 'odds' are of little consequence, what is happening to you is the reality, knowing some malaise is is common, rare, or influenced by some life factors has no bearing...
