Simpsons
I'm watching the Simpsons. The title of this episode is "Lesa's first word". They flash back to 1983. Bart is alive. and Lisa is about to be born. That would mean Bart is at least 21 now. Sheesh. What a baby-face. I think Bart is supposed to be ten years old. I think he has had about five birthdays though. Oh, well. It is a cartoon after all.

da Vinci Code
One of the things they little details in this book is that da Vinci wrote in reverse script that was indecipherable except in a mirror.  I sit here thinking of digital cameras and computer ciphers. I've read about encryption. The math doesn't always make sense.
