He died at 88. Didn’t have heart trouble till 82. Didn’t have dementia till 86. And he took more (types of) drugs than any human ever. So, he was just a little bit more healthy than average, no?

Edit: Thanks for sending me down the 5-HT2b rabbit hole. This was the cause of the Phen-Fen appetite suppressant heart issues. All psychedelics do seem to affect 5-HT2b receptors. I assume this is a dose dependent effect—where a daily high dose of Phen-Fen would be much more dangerous than occasional low weight psychedelic doses. But I appreciate the grounded caution and more research is clearly needed, ideally before I’m 70+.
