@noromance I understand "brain" as a scientific model, a mockup for explanatory and predictive purposes -- a reduction, or better, a neuroreductionism. I'm more convinced that what we term the "mind" emerges from interaction among brain, yes, but also body and our environment, both physical and cultural.
The use of "brain" is now rhetorical, very often. People recommend this or that based on it being "good for the brain" when they actually have very little evidence of that or even what it might mean for something to be "good for the brain."
