That is certainly an eye-catching title for inspiration for healthy aging! This is from the book Climbing Trees at 112: Real Life Inspirations for the Over 65s, by Vernon Coleman.
The book is full of stories of people (famous and not-famous) who did inspiring things after the age of 65, ranging all the way to the cover story of a 112-year-old man. It’s just a little 63-page book but I enjoyed it thoroughly. It helped pass the time while my wife was in the hospital.
