 No, I'm never tired of discussing aging. Dr. Louise Aronson is a geriatrician and professor of medicine at the University of California, San Francisco. Her best-selling book, Elderhood, is about redefining old age. I honestly think anybody who's lived past their 40s knows age matters, right? Your body changes, your brain changes. What I would like to see is a conversation where we actually discuss the things that matter.
