A study has found a linear relationship between old age and happiness. That is, the older you get, the happier you are.
Despite the deterioration of the body and the whole array of health and mental problems as people age, happiness increases. The linear relationship means that people in their 90s are happier than they were in their 80s, and in their 70s than in their 60s, etc. The biggest miseries are in young adulthood, the supposed prime of life.
I can relate to this. Consider the stress involved in trying to find someone to marry, in trying to find a job, in raising children, in trying to find success in one’s career. Older people are on the other side of all that.
But the continual growth in happiness in the post-retirement decades, that’s a mystery, and no doubt a gift.
