My then–eight-day illness coincided with President Joe Biden’s stricken performance at the first presidential debate on June 27; and so, I have been thinking about age and the limits it imposes on our energies; and how long it takes some of us to acknowledge its real impacts, as though we might have prevented our physical decline and mental slowdown. As though we are at fault.

Let’s begin with the obvious: The debate’s 9 p.m. start time in the president’s time zone is when most old people (including me) get ready for bed. He was tired! I’ve since heard that Biden had a cold that Thursday night, which explains the weak, scratchy voice. (Or was that the excuse the campaign invented?) Regardless, if Biden felt half as compromised as I have with my upper respiratory infection — when I have misspelled “horseradish” on the grocery list, run over a curb on a day when I had no business driving, repeatedly emailed “Christy” at work when I meant to send messages to “Crystal,” and committed any number of verbal gaffes with my antibiotics-addled brain — then I’d be willing to give the president a pass on his poor performance.

But I don’t think physical exhaustion explains it, unless you acknowledge it as a natural consequence of his age. That’s the conversation that anxious Democrats seem reluctant to have. Joe Biden is old. We don’t have to hide it, mock it or try to explain it away. When performing without the benefit of a teleprompter, or the psychological comfort of his team of aides, Biden acted like what he is — an 81-year-old man who is decades past his prime. And who should not be running for the most rigorous, visible and consequential job in the world.

I doubt whether Biden can be convinced to pass the baton less than two months before the Democratic convention, though the next-day New York Times column by his friend Tom Friedman made an eloquent and compassionate case for why that decision would serve the country. “[T]ime has finally caught up with him,” Friedman wrote. “And that was painfully and inescapably obvious on Thursday.”

Asked to bet today, I’d predict we are careening toward a second Trump presidency, which will be a disaster for the environment, for women’s reproductive rights, for immigrant protections, for an independent judiciary, for public-school funding and so much more. Perhaps, in the meantime, we can salvage a graceful exit for Joe Biden by ceasing to slap our foreheads and exclaim about his perfectly normal signs of aging: the shuffling gait, the search for words, the raspy voice, the stooped posture. All of which I remember from my own father’s decline, a man who, like Biden himself, had once been a sharp-minded attorney and politician, too.

As I stare down turning 67 on July 4, I am mindful that we can best locate empathy when we have experienced another person’s plight ourselves. It’s no surprise that I felt nothing but sadness for Joe Biden, who is nearly 15 years my senior, as he lumbered and stumbled onstage. I saw in him a quality that, until recently, I’ve been unwilling to see within myself — a refusal to concede to age, to recognize when it is time to step back and clear the path for younger people.

My upper respiratory infection hung on for 10 days and took two different prescriptions to kick because I had spent weeks performing like I was 20 years younger than I am. Having assured my retired husband I would scale back my work commitments this year, I instead stubbornly hung on to my two part-time jobs while taking on freelance assignments and contract work that I was afraid to turn down — all at a pace I once readily sustained. Mix too little sleep and too much multitasking with generalized stress, and you eventually get sick.

And if you’re old, you take a long time to get well.

I’ve since quit one of the part-time jobs and am scheduling my freelance work more carefully. But more than once during this extended illness, I have remarked to my husband that I tire more easily, that I must start prioritizing rest. “If that’s aging in a healthy 67-year-old,” I’d say, “how does an 81-year-old president do it?” Those comments now seem prescient, post-debate.

Neither my husband nor I is a huge Biden fan, but we are staunch Democrats and we’re afraid of Donald Trump. We’ll vote for Biden if he stays in the race and are trying to convince our Socialist older son that he should care enough to vote at all. The broader realization, however, is that we aging Boomers lack humility. We’ve been in charge for so long, during such a pivotal time in U.S. history — a period that I now recognize to be an anomaly of liberalism in a self-interested, deeply conservative country — that we can’t see our limitations and step off the stage.

We wouldn’t be in this position now if the Democratic National Committee had built a bench back when Biden was billing himself as a “transition” president, the only one who could defeat Trump in 2020. We wouldn’t be here if he had made more use of a Black female vice president whom, it appears now, he picked for show and to appease a constituency he couldn’t afford to alienate.

But here we are. The commentators who call for this clearly exhausted president to get on his feet again, prizefighter-style, to schedule interviews “in unfriendly places” and to forcefully compete are themselves still in denial. They’re asking him to summon a level of energy that most 81-year-olds cannot muster, let alone keep up between now and November.

Being this sick for this long, I have been forced to cancel appointments, to read and nap, to recognize that my body no longer will allow me to push at the edges of my energy. I can still contribute, but it’s going to have to be in different ways. Biden’s greatest gift to the country, to his family and to himself would be to make way for a successor and offer himself as the advisor and elder statesman that he deserves to be.

Some question whether the president, from his seat at the pinnacle of power, is capable of that level of self-awareness. “What was the combination of moral conviction, personal confidence and selfishness that propelled Biden, despite the risks, toward his decision to seek another term?” asked columnist David Ignatius in a Washington Post commentary that my sister shared with me the day after the debate.

To say that Biden no longer is up to the job is neither to blame him nor to deny the achievements of his administration. In fact, it is ageism — a perverse sort of shame — to avoid citing his diminishing capabilities. We aging Boomers must speak publicly about the realities we are experiencing as we grow old. Only then can we demystify and make peace with this most natural, and inevitable, of life’s progressions.
