1. Many, MANY things, my dear trof!

I think we were so deprived when we were young!

4. And I forgot Rubic's Cube!

2. It's amazing the changes, isn't it?

When my grandmother turned 100 in 2005, we made a book about all the changes in her life.

There was a page for each year since her birth, with one significant thing that happened - the beginning of Social Security, when the Lawrence Welk debuted on TV, the first "talkies", etc. - a short paragraph and a picture. My brother printed it on nice ivory paper, and took it some place to have it bound.

The name of the book - K's Grandma: The First Hundred Years. She loved it.

6. Wow. She's seen more than I have.

The birth of aviation.
And radio.

3. You left out the pyramids, the birth of Jesus, and Viagra!

[trof]

5. Oh hell. VIAGRA!

If we'd had that in college we would never have graduated and the unwed pregnancy rate would have quintupled.
Or worse.

[ohiosmith]

7. They had colleges?!

8. The contruction and then destruction of the Berlin Wall.

The pill.
