The In-Between

Too Old Is a Decision, Not an Age

It was almost midnight on Ali'i Drive in 2018. I had finished my own Kona hours earlier, legs cooked, salt crusted on my face, and I should have been horizontal in a hotel room. Instead I was back on the barricade waiting for an 85-year-old man I had never met to come down the chute.

The takeaways

  1. 01Too old is almost always an identity problem wearing an age costume; the real sentence is some version of I do not want to be a beginner in public.
  2. 02The shift from living to existing happens as a series of small no's, not as a single decision, which is what makes it dangerous.
  3. 03The adult brain stays plastic for life; what atrophies is willingness, not capacity.
  4. 04At 50 you have 20 to 30 years of practice runway, longer than most careers; the math on time almost always works.
  5. 05Add one thing each year that you are visibly bad at on purpose, to keep the part of you that can still start in working order.

I was 49 that year and my own race had not gone the way I wanted. The lava fields had taken more out of me than I planned for, the marathon had been a long negotiation with my own legs, and somewhere around mile 18 I had caught myself running the math on whether I was getting too old for this. That was the sentence in my head when I crossed the line. Not pride. Not relief. A quiet little audit on my own expiration date.

A few hours later I was back at the finish, in a folding chair I borrowed from a volunteer, waiting for Hiromu Inada. The announcer had been tracking him on the course all day. He had been moving for almost seventeen hours. When he finally came under the lights, the crowd noise was the kind you cannot fake. He was 85. He was smiling. And every sentence I had been telling myself at mile 18 went very quiet.

The next morning I was getting coffee at the hotel and overheard a guy, maybe 42, tell his wife he had always wanted to do a triathlon but he was probably too old now. I am not making that up. Twelve hours after Inada walked under the arch, a man less than half his age, and almost forty years younger than the guy I had stayed up to watch, had already filed the paperwork on his own obituary.

That is the thing I want to write about. Not Inada, who is the outlier. The 42-year-old at the coffee bar, who is the norm. And the 49-year-old version of me at mile 18, who was closer to the coffee bar than I want to admit.

Too Old Is Almost Never About Age

When people say they are too old to take up a hobby, learn an instrument, change careers, start a company, get back in shape, date again, write the book, or sign up for the race, they almost never mean the number. The number is the alibi. The real sentence underneath is some version of, I would be a beginner in public, I might fail in front of people who already know me, I have built a whole identity that does not include this, and I do not want to feel stupid.

None of those are age problems. A 30-year-old says it too. So does a 55-year-old and a 70-year-old. The age changes; the sentence does not. I wrote recently about I am statements and the identity you step into. Too old is one of the most expensive ones in the language. The second you say it, you have closed a door that was never actually locked, and you have handed the key to a version of yourself you invented on the spot.

The Quiet Shift From Living to Existing

There is a moment in most lives, and it almost never gets named, where a person stops adding new things and starts only maintaining the things that are already there. The calendar still fills up. The job still gets done. The kids still get raised. From the outside, nothing looks wrong. From the inside, the lights have been turned down one switch at a time.

That is the shift from living to existing. It rarely arrives as a decision. It arrives as a series of small no's. No, I am too old for that class. No, I am past the age where I would try that. No, that is for younger people. Each no is small. Stacked over a decade, they are the whole story.

The cost is not dramatic, which is part of why it is so dangerous. Nobody notices when you stop trying new things, including you. You just wake up one morning and realize the last unfamiliar thing you did was sometime during the previous administration.

The Self-Concept Hardens, And You Stop Noticing

The adult brain stays plastic. It does not switch off at 25 or 40 or 65. New skills build new pathways at any age; the pathways just need more reps and more sleep than they did at 19. The capacity is there. The willingness is what atrophies.

What actually hardens is the self-concept. Over time it wraps tightly around the things you have already done and quietly stops making room for the things you have not. That hardening is comfortable. It removes the ambiguity of being a beginner. It also removes the part of you that grows.

Inada did not avoid this by being unusual. He avoided it by being willing to be a beginner at 60, when he started training for triathlon, and a beginner again at 70, and a beginner again at 80. Each decade he added a sentence to his identity instead of subtracting one. Most people do the opposite. Each decade they subtract. And by the time they notice, the subtraction has been going on so long it feels like just who they are.

The Honest Math On Time

There is a real version of this concern that deserves a real answer. Time is finite. Recovery is slower. Joints complain. Mortgages and aging parents and businesses are real. The objection that you have less runway than you did at 25 is true.

The objection that you therefore have no runway is not.

If you are 50 and you take up something new today, you have a credible 20 to 30 years of practice in front of you, longer than most professional careers. If you are 65, you have what Inada had when he started. The math almost always works. The story you are telling yourself about the math is what does not.

What To Do With This

I am not going to turn this into a list of tips, because the work here is not tactical. It is a willingness to be a beginner in public for the rest of your life. That is most of it.

If I had to give it a shape, it would be three things.

First, the next time you say I am too old to, finish the sentence honestly. Replace too old with what you actually mean. I am too embarrassed to. I am too comfortable to. I am too afraid to look bad to. Sit with that sentence for a minute and decide if you want to keep it.

Second, add one thing this year that you are bad at on purpose. Not a stretch version of something you are already good at. Something where you are visibly a beginner. Not so you can master it. So the part of you that can still start does not atrophy.

Third, watch who you take your too-old cues from. If everyone in your circle has stopped adding, you will too. If one person in your circle is Hiromu Inada, even metaphorically, the ceiling in the room moves.

Back On Ali'i Drive

I think about Inada more than I think about most of my own races. Not because of the finish itself, but because of what the finish implied about every year before it. To stand on that line at 85, he had to have refused, hundreds of times across decades, the same sentence I caught myself flirting with at mile 18. He had to keep choosing I am an athlete when the easier sentence was I used to be.

That is the choice. It is not really about Ironman. It is about whether you are still adding to who you are, or whether you have quietly started the long subtraction.

Too old is a decision. It is almost never an age. And the decision is available to be unmade today, in whatever sentence you say next about yourself.

“Too old is a decision. It is almost never an age. The 42-year-old at the coffee bar and the 85-year-old on the finish line are saying very different sentences about themselves.”

Sit with this

  • What is the most recent thing you told yourself you were too old for, and what is the sentence underneath that has nothing to do with age?
  • What was the last unfamiliar thing you started? If you cannot remember, that is the data.
  • Who in your life is still adding new identities, and how often are you actually around them?
