Therapy and aging: New options for growth
Not only is it simply not true that our capacity for development shrinks with age, but it is also in fact critical for ongoing happiness that we prioritize development as we get older. That's right. To the extent that we think about development at all, it is thought of as a fairly circumscribed process that takes place "naturally" from birth into (roughly) early adulthood. What's implied (if not stated) is that at some point (generally that ambigous moment when we "become an adult") we're "developed." Which is to say, we no longer need to (nor can we) engage in an intentional, thoughtful endeavor to develop.
But that's precisely what we think is needed. Many of the so-called symptoms of aging, in our opinion, are symptoms of standing still developmentally speaking. For one thing, as we get older we often discover that things that worked very well for us no longer work. What's needed? We have to develop new ways of doing things! Sure, if you're out of practice, development will seem harder, and that can easily be mistaken as a function of age rather than a product of being out of practice.
