Mike Tschipper, a Canadian hard climber of the 80s who hung out with Rob Rohn etc., took a hit of acid one day and it triggered, I guess, his previously latent paranoid schizophrenia. The dude now requires 24 hr hospital care and has for the last ~22 years. But his Dad wrote an article in the CAJ that says even though Mike doesnt climb, he still remembers climbing, and likes reading alpine journals.
I think that would be worse than getting killed quickly by rockfall or an avalanche, myself.
