What about what I said implied anything about various other systems like stress hormones not being lastingly be affected by trauma?

I don't think most surgical patients are concerned with the kind of trauma their cells or gut microbiome sustain during surgery. In fact, if these systems recollected zero trauma it's doubtful the surgical outcome would be positive. When most people discuss suffering they are usually discussing the suffering of their selves. The self requires coordinated effort from the brain. When surgery occurs, it could be well argued you would want to use the least anesthesia necessary to avoid the kind of suffering the patient wants to avoid.

What are you actually on about? Why be purposefully insulting?
