I think at some point I may have lost my ability to delve into deeper thinking, some critical mass lost. I wish I could think better, less fuzzily. I like to break a thing down, analytically & get into the nitty gritty. I used to do this, but honestly the older I get, the less able I seem to be, or maybe even less interested. I'm not sure that's entirely right or fair to say--but it gets at the confusion and concern I feel about how my brain works, or doesn't, sometime.
I think the saving grace of brain chemistry is curiosity and kindness.
Manners have always mattered.
