My Aunt is 92. Her knees bother her, but she is able to live independently. She is aware, though, that her once sharp memory has a few holes in it. It made me sad to see her fret about something over which she has no control.
I told her that the longer we live, the more stuff we have in our brains. If we wouldn’t clean out and toss a few things, it would be terribly cluttered in there and we would have trouble finding what we needed for the day. The rule for an organized closet is to toss things we haven’t worn in a year or two, and if we bring an item in we should take an item out. Maybe the reason she remembers appointments and is still able to drive is because she tossed out the names of people she doesn’t see on a regular basis. Maybe her brain is as neat and organized as her kitchen. Maybe she’s just tossing and deleting old files. Just last week I lost a bill in a stack of junk mail. We need to toss that stuff! She seemed to like that idea.
