I wouldn't be surprised if these people are more calm, patient and mindful than most of us, correct? Are they elderly or extremely religious people?
They do seem to act differently than the rest of us.

No, that's the crazy part of it as to age. I know lots of peoples' parents and grandparents that don't have it, as can be expected. But they are maybe in their 80s and really don't give a damn. Usually they're the ones who live alone, so no young people around every day to insist on introducing them to it.
Funny about the religious folks. You'd think they might stay away, but don't believe I know a single one that has done that over the years. Amish, Mennonite types probably do that only through lack of electricity.
