A small game convention in Oregon (WagonCon - named so because it's in the town that wagon portion of the Oregon Trail ended in) has been going on for a few years now. Most years, I run a TMNT game. This year's no different - doing "Turtles are captured!" where you start off being held prisoner by Shredder.
I had a college professor that teaching was his fourth career, he was in his 90s. He started the first class of each term with "I'm not going to remember any of your names. I'm old. My brain can only hold so much. If I put your names in my brain, something else will fall out. It might be my wife's birthday, it might be that I need to take about a hundred pills a day. Either of those, and I'm dead by next week."
