Just terrific so far, Mark! I loved “Mad Men” and remember the brouhaha over “subliminal advertising” that purportedly got people to want or buy things they didn’t need.

You are SO KIND Ruth. Thanks for taking the time to read it. Long before I had a Substack I had thought about the damage of impulsive reinforcement. I am just a bystander but it seems to be an explanation why it is so hard for people to stop once they are in a bubble. We loved Mad Men. What a great show.
