I used to start to prepare several months before a doctor's appointment by starting a word document that I could use to jot down notes as things occurred to me to discuss with the doctor. I have an appointment with my PCP on Tuesday and am still at the "hmmm, I really need to do my notes for that appointment" stage ... I will do them but just find myself less driven to be as thorough as I used to be on things like that.
I am most definitely not there yet, but I can see a day eventually arising when I will startle my doctor by walking in without any prepared notes.
I am guessing that the damage in my parietal lobe is increasing as I am finding myself walking into walls more often (and have the bruises to prove it). It is not just because of losing my balance, although that is the reason sometimes. A lot of times it is just simply a matter of misjudging the distance between myself and the wall and realizing (often painfully) that I was closer to it than I thought.
