Dead or Alive settles bar bets and morbid curiosity. Brooke Astor is still alive at 102, and Richie Valens was only 17 when his plane went down.

The data seem pretty accurate, overall, even the strange cases. Jimmy Hoffa is listed as “missing”; Deep Throat and D.B. Cooper are “unknown.” Fifty-seven people have died in the last six months. How on earth do they keep this thing up to date?
