It seems from this NYT article that Tom Petty's death by accidental drug overdose had a lot to do with the chronic pain he was experiencing as a result of extreme pressure he was placing on himself to perform during his recent grueling 40-city last tour: https://www.nytimes.com/2018/01/19/arts/music/tom-petty-cause-death-opioid-overdose.html?rref=collection%2Ftimestopic%2FPetty%2C%20Tom&action=click&contentCollection=timestopics®ion=stream&module=stream_unit&version=latest&contentPlacement=1&pgtype=collection (Tom Petty Died From Accidental Drug Overdose Involving Opioids, Coroner Says) You can just read between the lines how every ache and pain he developed resulted in a prescription for another pain drug. Particularly revealing are the references to his hip problems and attendant pain. A complete perfectionist with his music, you can see how as the pain increased he continued to force himself to perform propped up by a pharmacopoeia of opioid pain medications. Interesting too how Petty expired after completing his tour. Sounds a lot like what Steve Ozanich refers to as the "Calm after the storm" when everything you've been repressing surfaces and creates the perfect environment for a TMS flare up (or a drug overdose).
