You had me at Gen X. I was born in 1971, so while a bit older than you, certainly of your generation. I still remember the fall of the Berlin Wall so vividly. In fact, I giggle now at the fact that my children don't even know a world with a Soviet Union. It makes playing classic Trivial Pursuit with them pretty fun for me, LOL Might I also add the following:

1. Freeing Nelson Mandela, 1990

2. End of Apartheid, 1994,

3. Chernobyl disaster, 1986

4. Challenger disaster, 1986 (we watched that shit on TV in school)
