Introduction

A few weeks ago, I opened my refrigerator and found a coffee cup sitting on the middle rack. Not something I’d meant to refrigerate, just an empty cup I had apparently placed there myself, with no memory of doing it. At eighty, these little oddities have become more common, but this one stopped me. It wasn’t alarming, exactly. Just… strange. A seam showing.

I’m not on the dementia or Alzheimer’s spectrum. My mind still works (as opposed to my knees). So, if this wasn’t cognitive decline, what was it? What was causing these small but unmistakable glitches?

With time on my hands, and my decades-long interest in what Abraham Maslow called the “Psychology of Being,” I figured I’d look into it. Somewhere in my past reading, I remembered a concept from the British writer and philosopher Colin Wilson, who emerged in the 1950s and spent the next several decades exploring consciousness and human potential. He described something he called the Robot, the part of the mind that handles routine tasks so we can think about other things. Driving is the classic example: after a little practice, the Robot takes over, and we can listen to a book, hold a conversation, or drift into thought while the car stays between the lines and gets to where we wanted to go.

I’ve been fascinated by Wilson’s Robot since I first encountered it decades ago. But only recently did I begin to see something new: these little lapses, like walking into a room and forgetting why, misplacing objects in absurd locations, losing the thread of a thought mid-sentence. I began to think that these weren’t signs of a glide path toward dementia. Instead, they were signs that my Robot wasn’t working as well as it once did.

And as I started comparing notes with friends (the ones who are not just old friends but actually old) it became clear that these glitches weren’t personal quirks. They were part of a much bigger story unfolding around us.

In 2026, the first Baby Boomers turned eighty. It didn’t make headlines, but it marked the beginning of a demographic shift unlike anything the country has seen. For the next decade, roughly 8,000 people a day will cross that same threshold. By the mid-2030s, the number of Americans over eighty will double. Nearly thirty million of us will be living in a stage of life that previous generations rarely reached, and never in these numbers.

Most conversations about aging focus on exercise, dementia rates, fall risks, medications, Medicare. What’s missing is the interior experience. What it feels like to be inside an aging mind. What it means when the routines and automatic behaviors that carried us through decades of life begin to slip in small, odd ways.

And here’s the reality that no one likes to talk about: some of us will get dementia. The numbers are what they are, roughly 20 to 30 percent of people over eighty will develop some form of it. This book can’t help them. But those numbers also mean that 70 percent of us will not. That’s about twenty-five million people who will live into their eighties and nineties with their minds intact, and yet virtually all of us will still be terrified of the possibility. The possibility of getting dementia has become the great unspoken fear of our generation, the shadow that follows every misplaced object, every momentary blank. This book is for the people living under that shadow.

Because once you take dementia off the table for the majority, you’re left with a different question entirely: If it isn’t dementia, then what is it?

What if these glitches are not the glide path to decline at all, but simply the aging of that part of the brain that runs the Robot? And what if that aging Robot is something we can easily compensate for? More importantly, what if the act of compensation — stepping in where the Robot once handled everything automatically — opens a door to a richer, more conscious and surprisingly satisfying way of living?

If that’s true, then these small glitches aren’t warnings. They’re invitations.
