I don’t think it was a coincidence that Steve Jobs died the day after the keynote. Sometimes the will to stay alive is very powerful.
From the Wikipedia entry on Charles Schultz:
Charles Schultz, the creator of the Peanuts comic strip died almost immediately before the last Peanuts strip to retire the series was published.
“Peanuts ran for nearly 50 years, almost without interruption. During the life of the strip, Schulz took only one vacation, a five-week break in late 1997 to celebrate his 75th birthday; reruns of the strip ran during his vacation. At its peak, Peanuts appeared in more than 2,600 newspapers in 75 countries. Schulz stated that his routine every morning consisted of eating a jelly donut and sitting down to write the day’s strip.
In a December 1999 interview, holding back tears, he recounted the moment when he signed the panel of his final strip, saying, “All of a sudden I thought, ‘You know, that poor, poor kid, he never even got to kick the football. What a dirty trick — he never had a chance to kick the football!’”
Charles Schulz died in his sleep at home around 9:45 p.m. on February 12, 2000. The last original Peanuts strip was published the very next day, on Sunday, February 13, 2000, just hours after his death the night before.”
