Active aging requires us to go on living life to the full no matter how differently.
One of the clearest signs of healthy aging drawn from the Harvard University longitudinal Study of Adult Development becomes more important as life spans increase. Lifelong learning, the study says, makes the difference between healthy and unhealthy aging. It determines the degree to which life will be satisfying to us, as well as the degree to which we will be interesting, valuable, life-giving to others.
