Here is a site that will make you feel old - or a part of history - depending on your attitude. There, I learned that I was:
26 years old at the time of Oklahoma City bombing
20 years old during the fall of the Berlin Wall
16 years old when the space shuttle Challenger exploded (I remember very acutely where I was when that happened)
14 years old during Sally Ride's travel in space
12 years old when Pres. Reagan was shot by John Hinckley, Jr.(Again, I remember that one very clearly)
10 years old at the time the Iran hostage crisis began
7 years old on the U.S.'s bicentennial Fourth of July (Yeah, I remember this too)
5 years old when President Nixon left office
not yet 1 year old at the time the first man stepped on the moon

I am also
52 years 4 months younger than Walter Cronkite, age 85
48 years 9 months younger than Pope John Paul II, age 81
22 years 8 months younger than President G.W. Bush, age 55
3 years 0 months younger than Cindy Crawford, age 36 (ha ha - I'm younger than Cindy Crawford!)
6 years 10 months older than Tiger Woods, age 26 (Yeah, but that's not much of an age difference, is it? I mean - if he and I ever were to meet, you know? I wouldn't mind hanging out with a younger man. Especially not if he looked like Tiger Woods...)
