The consensus seems to be that super aging is measured by memory [“Super Agers,” Cover Story, November]. I’m 81. I play pickleball six days a week. I jog occasionally. I just updated my textbook (the 11th edition). Yet I’ve always had a terrible memory. I have a doctorate from Harvard Business School. My degree didn’t require good memory. It required critical thinking and analysis. Perhaps researchers should develop other measures to determine whether one is a super ager.

I loved the article. So many people seem to think that if you’re over a certain age, you’re old! I work out, wear heels all the time and try and keep up with fashion. So many times, women will say, “Oh, you’re old. Let yourself go. You’ll be happier.” I don’t subscribe to that attitude.

Thank you for the excellent articles “Fixing the Caregiving System” and “The Emotional Toll of Being a Caregiver” [AARP Update]. I’m a retired 50-year-old RN, and I’ve been caregiving for a disabled husband for over five years. This is truly one of the hardest jobs I’ve ever had. Your articles were thorough and informative. I support the tax credit for caregivers.
