Sitting down with the author of the best seller "Elderhood," we found Dr. Louise Aronson pleasant but with a forceful message. It's about about disrupting stereotypes and demanding fairness from a healthcare system geared to coddle youngsters and help ease adults from their 20s through middle age. In the author's own words, it's for anyone who is "an aging, i.e., still-breathing human being." Yet, as you'll hear, Dr. Aronson delivers it all with a positive outlook about getting the most out of all your years.

One dictionary defines a gym rat as “someone who spends all leisure time playing sports or working out in a gymnasium or health spa.” The last guy you’d expect to fit that is a 97-year old Holocaust survivor named Ben Heller. But six days a week you’ll find Ben on the treadmill or cranking one of the weight machines at an Atlanta fitness club. Ben has won the respect of millennial club members amazed by his Just-Do-It determination. Especially when they learn his backstory of survival during three grim years in a WWII Nazi death camp. Ben told us about his remarkable life, right after—what else?—a long workout at the gym.
