Of course, there were occasional outside interruptions to my rhythms. Beginning in the late 1990s, an enlarged prostate led to increasingly problematic sleep. Four or five trips to the bathroom each night became routine. A TURP (the “roto-rooter” prostate surgery) procedure in 2011 helped enormously, but years of interrupted sleep had trained my body to wake repeatedly. Even after this medical issue improved, the habit of frequent awakenings lingered. But throughout it all, I remained an early riser.
Ultimately, retirement had its impact on my lifestyle. While there was no conscious decision to sleep in later, there simply was no longer a reason to get up before dawn. Without really intending it, I began getting up a little later. And then later.
Today I’m usually asleep by 10:00 and awake around 7:30, about two hours more sleep than during most of my working life. At age seventy-nine, I now sleep considerably more than I once did. That surprised me because I’d always heard that older adults need less sleep. Curious, I did a little reading and discovered the research isn’t nearly as settled as the popular wisdom suggests.
While I was at IU, one of my closest friends seemed to function quite well on four or five hours of sleep each night, but I always needed much more. We were both a little skeptical of the other’s sleeping habits. I couldn’t imagine getting by on so little sleep, and he probably thought I was a slacker. Looking back, I guess each of us believed our own rhythms to be the “normal” ones.
What has stayed with me, though, isn’t the research itself or the sleeping habits of others. Rather, different questions altogether poke through. If my body now prefers a schedule so unlike the one I had followed through most of my adult life, what’s changed? Has retirement simply given me permission to sleep more? Or had I spent decades assuming that my work schedule reflected my natural rhythm when, in fact, I had gradually adapted myself to the rhythms of the institutions where I worked?
For more than half a century, my life was organized around the schedules of schools, colleges, and universities. Over time, those rhythms became so familiar that I stopped noticing they belonged to the institutions where I worked. I experienced them as my own. I believed I was someone who naturally woke at 5:30 every morning. Maybe I was. Or maybe I had simply spent decades living by rhythms that were never entirely mine?
