The term “senior” officially applies to those sixty-five and older. But not everyone who is called a senior feels like a senior. And not everyone who retires is sixty-five. Some retire at fifty, some at eighty. Age is a relative thing. Most working artists never retire. As director John Cassavetes put it, “No matter how old you get, if you can keep the desire to be creative, you’re keeping the man-child alive.” Cassavetes himself was a fine example of what might be called “youthful aging.” He both acted and directed, making and attending films that reflected his own convictions. Working with an ensemble of actors that included his wife, Gena Rowlands, he told tales of intimacy and connection. As he aged, Cassavetes cast himself in his films, portraying troubled and conflicted men. His passion was palpable. Even if he played the oldest character in the movie, he was always young at heart. Taking a cue from Cassavetes, we can retain a passionate interest in life. We can throw ourselves wholeheartedly into projects. At sixty-five, we can still be vibrant beginners.
