Reference Back.

I feel like kids today are pretty lucky in what they learn about at school. I mean, when I went to school, dark matter wasn't something we learned about. It was what we had for lunch, or what some of us thought we were made of, if we'd been listening to The Cure. Also, the computers we used back then had the same amount of memory as today's calculators and the calculators had no memory at all, due to the fact that they were small piles of stones or bone shards.
