About three times in my life, about 5 to 10 years ago, while driving and thinking about facets of my life that made me angry, I got a sharp pain near but just under the skin along a line, front to back, near the top of my head, but to the right, about where the right stripe on a U of Mich football helmet is. I realized that I needed to concentrate on becoming calm, and it went away after a minute or so. I now know thatI must overtly know not to get angry, but, over the past three years I realize that I cannot think as well as I used to. Fortunately or unfortunately, I do not now nor have I ever held a work position that demanded much deep thinking, but being unable to think. or even want to try to think, like I did when I was younger is discomforting. This really struck me about November 2011. I was writing a blog about 3 times a week, and I just didn t feel like thinking deep enough to make sense anymore.
