As I get older and older, I become increasingly convinced that my brain is just shriveling up like a tomato in the sun, and I need to keep feeding it and testing it to keep it ripe and juicy. Sometimes that means teaching myself something useless and new, like how to solve a Rubik's Cube, and sometimes it means playing the same Sporcle quizzes over and over again.
I love pub quizzes, and I love news quizzes, and I love quizzes that ask me to name every Doctor Who episode ever, especially when I can get better at them. The first time I tried to name all the 21st century episodes I managed around 55 percent. Now it's 100 percent, all the way, and I can easily name each adventure.
I also find the picture searches on Sporcle weirdly comforting - trying to identify all 260 Marvel characters in this picture gets things humming, even though I always, always fall about 15 short.
Look, I know there are better ways to keep the brain turning over, and certainly more useful, but I'll take what I can get. Knowing the title of every single episode of Doctor Who isn't big or clever, and nobody is ever going to ask me about it, but it's there now.
