Thank you for this comment. For my job, I am driving in my car anywhere from 4-6 hours a day. You could say I am just sitting there, why don’t I have energy to do anything else with my free time? I’ve recently begun to realize that while driving all that time, my brain is making thousands of subconscious decisions. I don’t have any study to back this up, but I think the brain only has so much capacity for decision making each day.

Many days, I end up zonking out for a 20-30 minute nap in the afternoon. It’s a visceral need to sleep right then. And then I can function at a better capacity for most of the rest of the day.
