Old age is very different today, when the average lifespan is 79, than at the turn of the 20th century, when it was 49. It’s a new stage of life, like adolescence emerged 70 or so years ago.
An interview with Louise Aronson, author of the book “Elderhood: Redefining Aging, Transforming Medicine, Reimagining Life." From the book description on Amazon:
For more than 5,000 years, “old” has been defined as beginning between the ages of 60 and 70. That means most people alive today will spend more years in elderhood than in childhood, and many will be elders for 40 years or more. Yet at the very moment that humans are living longer than ever before, we’ve made old age into a disease, a condition to be dreaded, denigrated, neglected, and denied.
In the words of Doc Holliday: “I’m in my prime.”
