very recently a favorite facebook friend & a fellow traveler of a school I wnt to when I was 15 & he was 13, I left & the next year he came, so we actually never met, He also lived in the same small ca town where I grew up.

John was driving & had the heart attack, he manage to pull pff to the sde of the road & turn off the car before he died. He will be sorely missed. when I commented a few years ago when he first mentined his trouuble & I mentioned that I didn't think conventional therapy for cancer was good, that he & i were of two different tribes/ wiki said way far doen on the list of side effets danger from death from heart attack as an effect of the ratiation
