Warning: Reading your own obituary can be hazardous to your health.
After suffering a stroke in 1940, black nationalist leader Marcus Garvey became incapacitated. Rumors began to circulate that he had died, and before Garvey could quell them, he ran across a premature obituary for himself in the Chicago Defender which described him as a man who died “broke, alone and unpopular.” According to people close to Garvey, upon reading it he let out a loud moan and collapsed to the floor, where he suffered a second stroke. By the following morning, he was dead at fifty-three. [Link]
