Had a very close friend who passed away years ago from it. We tried various things, from apricot pits to a hat with electrodes attached to his head. Nothing worked.

He died about a year before John McCain died of the same. I regretted that we didn't try to do more, but, seeing that it took McCain in the same length of time did make me feel a little bit better (not that I was happy for McCain's death, but that his connections and world-class treatment made no meaningful difference in how long it prolonged his life versus that of my friend).
