July 30, 2017: Thanks to those of you who commented to me about my return-to-action essay last week. For many who are not on Facebook, I enjoyed reconnecting. One person noted that I had transitioned from curing cancer to promoting diabetes by helping advertise fast foods. I’m guilty on that point. Her comment did inspire me to examine the Facebook advertising rules to see if I could get a cigarette account and go all-out “Mad Men” – but that category is forbidden.
