If what to do during retirement is an unanswered question for you, why not pick up a study? Studying late in life comes with an enormous amount of advantages. See it as a kind of exercise. It keeps your brain fit. And don’t worry about your brain: it’s stronger than you might think.
Both Hannie and I never stopped educating ourselves. We probably will be studying as long as we can read and listen. Lately I have been picking up my old love for literature again, more specifically for poetry. This gives me much pleasure.
However, the question is why you should study late in life. Of course, because to study gives pleasure. Yet there is more to this question that meets the eye.
