So far, life seems to be largely on the upswing for this run-of-the-mill radio producer. I had some dark days in '04 when I was unemployed, but since then, the sunny days have far outnumbered the stormy ones (which is not to say I don't love a good storm). People keep insinuating that I should be concerned about 30, which is right around the corner, but I always respond, "Why worry? 27 was good, 28 was even better, and I absolutely love 29 — aging is great!" Turns out, maybe Pollyanna over here should be listening to her questioners. A new study shows depression in middle age peaks at age 44 (or, should I say, it valleys?). Sure, at 44 I may have many more responsibilities than I do now — possibly a big mortgage, possibly a marriage, possibly kids — and those are just the good things that could place demands on my time... What if divorce, death, and debt are around that bend? Either way, a slump at 44 is likely for folks worldwide, and there may even be a biological reason for it. The good news is, it's a U-shaped plot, so you'll pull out of it as you age... But on the flip side, that means folks my age are looking at the downward slope. Have you experienced depression or unhappiness in your 40s? And did you come out of it with age? What made the difference?
