You're getting old when...

I just heard a funny story on my way into the lab this morning. A woman on the elevator was holding a typewriter and I jokingly commented that I couldn't believe people still used those things. One of the professors down the hall, who was also on the elevator, then told us that his son recently came upon their old typewriter. After playing with it for a bit, he turned to his dad and said, "This computer is really cool. When you type on the keyboard it prints out immediately."
