Staying up is good for you.
I just watched the most fascinating thing in the WORLD on the National Geographic Channel... about how Leonardo da Vinci could have been responsible for creating the Shroud of Turin --- and it's the most convincing and interesting argument I've ever heard (and believe me, I've read/watched a lot about it). Wow. From when it came into popularity to all of the controversy as to how it might have been made, and Leonardo's personality and history... holy shit. That was possibly the coolest thing I've seen on television in years.
