My aging memory
If something makes me think back 10 or so years to a person I haven't thought of for quite a while, I may not be able to recall the person's name. I know I used to know it but I cannot make it come to mind. That is more or less a classic aged memory problem. I try to find a way around needing to recall, using old records or vague language.
But things that repeat are a little different. I have breakfast every morning. I make dinner every other night. I often have trouble remembering the last time and not confusing it with other recent times.
