I just finished listening to the audiobook 30 Lessons for Living: Tried and True Advice from the Wisest Americans by Karl Pillemer, Ph.D. After gathering data from interviews with over a thousand older Americans, whom the author refers to as the "experts", Dr. Pillemer provides the advice of the elders in a consolidated form. I appreciated that author ended the book with a list of ten questions for readers to use when conversing with their senior relatives and neighbors.
I am always on the lookout for good advice, especially if it is something timeless that I can share with future generations. What I found in this book is nothing that I have not heard before. It did remind me, however, that one of the keys to a long life is to eliminate chronic stress.
When I was younger, I used to hear stories from World War II and Vietnam War combat veterans. I had noticed a trend in that most of them seemed to have been very lucky in escaping close calls. Then one day it dawned on me that I had been only speaking with the survivors.
I see some of the same data bias in this book. The main criterion to be considered an expert by the author was to have lived a long life. Many of the interviewees had enjoyed stress-free lives for multiple decades due to not having significant responsibilities since retirement.
I started thinking about this bias because one of the lessons was that people get out and see the world while still young instead of waiting until later when they might be too old for travel. This contradicts the make hay while the sun shines philosophy of the Financial Independence, Retire Early (FIRE) movement. Until one has actually achieved financial independence, as almost by definition most retirees have, one will not have the hindsight to know whether any travel experiences leading up to that point were life-enriching or just doom spending.
