Old Age too creeps up on little cat feet. It happens while you are busy doing something else, usually something far more interesting. And it happens so gradually that you don't realize it is happening to you. Which is fine because it really isn't a big deal.
When we were young we all expected being old to feel very different from being young, but it doesn't, at least not enough to be a qualitative change. More often, getting older is something that you notice in other people, not in yourself.
But once in a while you get clues from the way other people behave toward you. More people call you "Sir" or "Mister." Nobody calls you "Dude" or "Guy." Once I was called "Grandpa." A few weeks ago I was carrying some groceries onto a bus and a young woman offered me her seat. Sales clerks seem more willing to offer assistance, I suppose thinking I am more likely to need it. A casual acquaintance at a bar recently asked how old I was and let out a little gasp when I told him, as if to say, "What? And not dead yet?"
Another clue is that most of your old college professors, all the major modern thinkers you learned from, most of the modern authors whose books you enjoyed are now dead--even the long-lived ones. Just to take a few recent examples, Milton Friedman, Kurt Vonnegut, Barbara Gittings. Many others died further back--in the 1970s and 1980s. You get the disconcerting feeling that it all depends on your generation now. I sure hope the others are doing their part because I can't do it alone.
You become vaguely aware that time grows shorter, that there are a lot of things you've been meaning to do "someday" and that if you don't do them pretty soon you won't get them done ever. As of my birthday a few days ago, the actuarial tables give me several more years, which isn't so bad, really. You can do a lot in several years.
But the point is that somewhere along in the aging process you begin to take seriously the idea that life has a terminus and that--surprisingly--this actually applies to you too. This is nothing as big and gloomy as the Existentialists' "sense of one's own mortality," just a kind of "Oh, if not now (or soon), then never."
So you have to begin a kind of triage among your various goals, casting aside the less important and never-very-heartfelt ones (e.g., reading Proust), and resolve at least to begin working on the others. In the last few years, for instance, I've been spending some of my free time learning more about art to make up for a deficiency in my education. It turned out to be enjoyable as well as interesting.
For the same reason, I've started occasionally reading some books generally regarded as a "classic," many of which turned out to be pretty good. Other people will have different goals: travel to a foreign country they have never seen, taking up a hobby or craft, getting involved in local politics. Whatever it is, it is time to do it.
One of the most common beliefs about growing older is that aging is accompanied by a decline in energy level. No doubt that is true. But the decline is so gradual that you hardly notice it and scarcely feel the loss as it is occurring. Don't worry about it. Just accept it as part of the gift of a long life. A lot of gay men never got that gift.
One of the great benefits of growing older is the natural ability to act mature. Most of us who are older have, I think, developed a kind of reserve and restraint, a degree of emotional stability, a bemused attitude toward life, a greater degree of empathy in our relationships, and a broader perspective. Those are gains not to be disguised or abandoned.
Once in a while you see some older gay man acting as if he were in his 20s, as if he thinks that is a great age to be. It doesn't work. In fact, it only highlights how old he really is by drawing attention to his failure to be what he is trying for. People, including the young, will respect you more for being a good example of whatever age you really are.
And frankly, young gays need older gay people as exemplars of how they themselves can grow up rather than remaining, for lack of visible alternatives, in the state of perpetual adolescence we sometimes see in younger gays at the bars. Our "culture," such as it is, must get over the excessive focus on youth and youthfulness. Even if it is only a stereotype, it is one that we help perpetuate by not challenging it directly.
