I hope not, I recently retired. Still, the idea makes some sense. In retirement, I try to read one paper a day (usually deep learning, PGM, or classic AI), play at least one game of Go and Chess, do some recreational programming, and read. But, I don’t work into a state of brain-tiredness anymore like I used to at work.
Statistics are useful for understanding a population but not for an individual. Some people get bored without work. I have never felt bored when not working. My grandfathers both worked as professors until they where forced to retire due to Alzheimers. Running marathons and working into their 70s didn't stop their mental decline. Should I focus on the statistics or my genetic history?
Do you exercise? Lifting weights regularly (3 x week) and getting some light cardio every day will help keep your body strong into your retirement. It dramatically reduces the chance of getting injured by a fall and will keep you healthly and happy longer.
I'm approaching 40 and have built it into my schedule after several years of doing little and I'm feeling great for it. Next year we're moving to a large house and I'm going to have a small gym in the garage so I can keep to a tight schedule (I miss too much training because of having young kids).
I hike at least ten hours a week (I live in the mountains) and go to the gym once a week. Your advice is excellent. My Dad is in good shape at 98 and he does thirty minutes of Canadian Airforce Exercises early each morning (he started doing this in 1964).
