I'm taking a course about the brain/mind - lots of .in depth information about structure and connections and all that -- a bit too theoretical. I read a lot about the subject and remember tidbits that may or may not be true. I suppose they're the parts I want to remember. Sometimes I try my own one-person completely uncontrolled nonstatistical experiments. One such bit of probably pseudo-science I read and remember is that smiles are at least a contagious in a crowded place as are yawns. Off and on I used to try it on the NYC subway -- get on, look around the car, smile at nothing in particular. Of course most people didn't actually look at me and see the smile, which, sometimes I tried to keep on as long as it could be sincere. I can't say I proved anything even to myself except that it actually feels good to smile. But then I knew that.
Emily Dickenson, being a woman of a different time, and certainly not often among crowds of people (if ever?) wrote a little more thoughtfully about smiles in this short poem (#1391)
They might not need me -- yet they might --
I'll let my Heart be just in sight --
A smile so small as mine might be
Precisely their necessity --
The mid-70s are a surprise! Part of me remains in the 50s -- age, I mean, not decade of 20th century. It's a joy ride, new experiences land in my lap and I've become a better quilter, poet, writer than I expected. It's a rich life for a person never rich financially. Hey, this is what the mid-70s are like!
