I Got Circadian Rhythm

My timing seemed to be off today. I've been awake since around 4:30, but can't seem to get up the energy to do very much other than work-from-home. Thank goodness I didn't have to schlep into Manhattan today, my aching legs and feet and IT band and whatever would not have liked that very much. This evening we watched a fascinating documentary about Life On Earth, a late '70s nature program by Sir David Attenborough, who turns 100 years old on Friday. Robin remembers seeing the show on BBC in the '70s, I don't think it ever made it over here. Then we watched a program made a couple years ago about dark matter, which still makes my head hurt, but the main thing was how much our understanding of the cosmos has changed since I was in high school. Say, did you know that Jupiter has way more than 12 moons?
