We tend to believe that the mind affects the body and the body affects the mind, although we do not generally believe that everything we do affects the brain. I am convinced that if someone was to yell at me from across the street my brain could be affected and my life might changed. That is why your mother always said, ‘Don’t hang out with those bad kids.’ Mama was right. Thought changes our life and our behaviour.
Note to self: Upon seeing Milton Glaser on the street, do not yell out to him—you might change his brain. Which, I don’t know, sounds dangerous.
P.S. It’s worth nothing that the bit I quoted from Glaser’s essay is grounded in Scripture.
