It seems like our thinking is in overdrive times the number of other parts awake at the same time. A singleton carries (assuming) one line of thought but whereas we are many thoughts sometimes conflicting in nature or complimentary.

This is mentally taxing to the point of mental fatigue. Then for the brain to have active parts even while sleeping, to be in REM sleep but parts awake....

Can this cause a significant amount of brain aging in a person where the brain is actually older than the body? Headache causing? Brain cramps? Brain cringing?

We often times, even during the day, are literally too tired to think. I know I’m physically tired at times....but days and hours on end of furious nonstop brain activity....

Then with a bipolar drive to it...

Or am I just getting old?
