The only “doublethink” is how you claim not to be opposed to exercise in one comment while denigrating the very thought of going to the gym in another, in spite of clear evidence that lack of exercise is broadly detrimental to one’s mental state, rather than your narrative of “self-medication with endorphins that induces dependence and withdrawal symptoms where none existed before”. And claim that some source of endorphin release is good when that contradicts your only rationale for equating exercise with opiate abuse.
