Fact #28: In 1909, Mark Twain predicted his own death. His prediction was accurate – Twain died of a heart attack on April 21, 1910, in Redding, Connecticut, one day after Halley's Comet closest approach to Earth.
He is quoted as saying:
"I came in with Halley's Comet in 1835. It is coming again next year, and I expect to go out with it. It will be the greatest disappointment of my life if I don't go out with Halley's Comet. The Almighty has said, no doubt: 'Now here are these two unaccountable freaks; they came in together, they must go out together."
