What has made you feel especially young/old lately?

Yesterday at work, a coworker mentioned in passing how long she had worked there. She said fifteen years, which floored me. But then she thought for a minute, and, remembering that she started in 1996, realized it’s been closer to seventeen. I shocked her then by saying, “You realize I was born in ‘96.” She felt especially old for a minute, and I felt especially young. It was an interesting moment for both of us.

So, my fellow jellies: Has anything put your age in perspective lately? What did you think about it?
