Kind of on topic. The parasympathetic nervous system is operated by that 90% of the brain we supposedly have no access to.
Wouldn't it be a bitch to try to walk and simultaneously, consciously control the contractions in you digestive system and get that digestion task
Even walking is mostly reflex and requires little or no thought.
I have a unique perspective on this as I had a really bad stroke sixteen years ago.
Most of the things I took for granted, I had to relearn how to do.
That included a lot of autonomic processes that I didn't even have to think about, that I had to take special consideration of and for, to help my
body to do things while I was recovering from the brain injury.
Not entirely on topic.
I do think that when the autonomic/parasympathetic NS is working on a light load, like when the body's needs are all taken care of and homeostasis is
just humming along with little effort by the autonomic/parasympathetic NS, that the excess processing power that is no longer needed for utilization
by the body processes get used like RAM memory does in a computer.
No need for drugs or mind altering substances....
