According to Newton anyway. CNN.com posted this story about a series of papers written by Isaac Newton, in which he predicted that world would not end prior to 2060. According to the CNN story, Newton wrote, "It may end later, but I see no reason for its ending sooner."
This works out perfectly for me. For a long time, I have said that when I turn 80, I'm going to plant myself on the front porch with a carton of cigarettes, a case of Jack, and a loaded shotgun.
I was born in 1980. So by 2060, I'll be . . . you guessed it, 80. The timing couldn't be better. I'll be able to sit, smoke, drink, and just wait for the end of the world!
