Well, you can die for a cause. 1991, Amherst MA USA, at
  Hampshire College. Smelled a sickly sweet smell and a light
  blue-gray smoke crossing the campus. It was gross and yet almost
  familiar, like I'd heard of it somewhere before. Find out later
  on, a guy had self-immolated to protest the war in Iraq from
  Prez Bush #1. The vapors drifted through the woods and made it
  to the school from the center of town. I remembered the smell
  because of an old TV show that described the smell and look of
  spontaneous combustion and that was it. Anyway, I dunno what he
  accomplished, but at least he became a story.
