The brain doesn't seem to ever "clock down" when it's idle, which is interesting to me

maybe between sleep and normal waking idle because there is actually quite a bit going on during sleep. There has been quite a bit of research though regarding higher "clock up" states consuming far more energy, such as grandmasters playing a chess tournament

My lazy research pointed to 6K calories which is a lot more than a typical person can burn by physical exercise.
