DEAR DOCTOR K: I am in my mid-60s, and I'm worried I might be getting more forgetful than normal for my age. I function fairly well most of the time. But sometimes I'll forget something like the details of a phone conversation I recently had. How can I know what's normal?
DEAR READER: You sometimes forget things you didn't used to forget? Well, join the club. Each of us has more difficulty remembering things as we get older -- it's a normal part of aging. Like thinning hair and stiffer joints, subtle memory problems are common.
