Redefining Middle-Age as Masters and Beyond
I vote we eliminate the term “middle-age” and adopt the terminology of the long-distance runner. In that arena the age-groups beginning at age forty are known as “Masters” runners. Race entrants are divided into five-year age groups: 40–44, 45–49, 50–54 and so on. Why not? People over forty are now “Masters” and, if they must, can compare themselves to the other members of a five-year cohort.
