I had a 3-year-old toddler at 47. My wife and I had waited, for all the reasons people wait — careers, timing, complications, and a version of reality where I thought I had all the time I needed. When he was born, the timeline math showed up for me like a slap in the face. Not a cinematic moment. A quiet moment at 3 AM holding a newborn and realizing I needed to be around for a long, long time, and that "being around" was now a specific operational problem I had to solve.
Before a 3-year-old toddler, longevity was a podcast topic. I knew the names. Peter Attia. David Sinclair. Peter Diamandis. I'd sit in Singularity University lectures about the abundance thesis and nod along about how humans were going to live to 120. It was interesting. It was theoretical. It was a thing that mattered for "the future of humanity," not for Tuesday morning.
Now it's Tuesday morning and I've got a three-year-old asking me to chase him around the living room, and the back pain I'm managing is suddenly not a luxury problem — it's a a 3-year-old toddler problem.
The real inventory (not performative)
Let me tell you what's actually going on in my body, because I'm tired of reading founder-health content from 35-year-olds who act like discipline is the only variable. At 50, discipline is table stakes. The variables that matter are the ones you can't out-hustle.
Back pain. Serious enough that I've had spinal injections. Serious enough I flew to Korea earlier this year for treatment. This is not the kind of thing you "push through." This is the kind of thing that tells you, very specifically, that you cannot carry your three-year-old on your shoulders at the zoo without consequences, and that is a line item in the cost of having kids later.
GERD. Uncomfortable. Manageable. A constant reminder that the 30-year-old diet I used to run on — coffee, deal food, whatever was fast — is not a sustainable operating model for the body I have now.
Cholesterol. In the range where I need to pay attention. Not yet in the range where I need medication, but close enough that the trajectory matters more than the current number. Peter Attia's Outlive is the book that reframed this for me — the point is not your cholesterol today, it's the 20-year exposure profile.
Vision. Noticeable decline. Not dramatic. Just the thing where you start holding the menu further away and then you start squinting at your phone and then you finally admit it's time to get progressives.
None of this is catastrophic. All of it is the beginning of a conversation the body is having with me that I need to answer clearly, now, while the conversation is still early.
What I stopped doing
The longevity podcasts will tell you to add things. Supplements. Cold plunges. Red light. Peptides. I've tried some of that. The thing that's actually moved the needle for me has been subtraction, not addition.
I stopped pretending sleep was optional. At 35, I slept when I could and acted like 5 hours was heroic. At 50, 5 hours is not heroic — it's self-sabotage that will show up in my judgment the next day. I protect 7+ now. I say no to things that would push me below that. I book travel around sleep. It is the single highest-leverage decision I've made for health, and it has nothing to do with supplements.
I stopped eating like a road warrior. The airport food, the drive-through, the "I'll grab something" lifestyle was fine at 30. At 50, it's a loaded gun. I'm not a monk — I still eat Korean BBQ and I still have wine — but the default setting changed. Default is now "what would a 70-year-old version of me thank 50-year-old me for eating?" Default is not "what's fast?"
I stopped treating exercise as a career input. For years, I exercised because I wanted to show up to meetings with energy. Now I exercise because a 3-year-old toddler wants to chase me and I don't want to have to say "Daddy's tired." That is a very different incentive. One is performative. The other is unconditional.
What I started doing (that actually worked)
1. Annual full-body labs, interpreted by someone who cares. Not the standard annual physical. I get the real panel — lipid subparticles, inflammation markers, metabolic panel, hormone panel — and I review it with a physician who takes time to explain the trajectory, not just the numbers. If you can afford one longevity-focused expense, it's this.
2. Strength training, not cardio. At 50, muscle mass is the single best predictor of how well you age. Cardio is important but it's not the lever. The lever is maintaining muscle, which means lifting heavy things consistently, which I was not doing at 35 because I thought cardio was the whole game. It's not.
3. Walking with a 3-year-old toddler. Sounds soft. It's not. 30-45 minutes a day outside with a 3-year-old toddler, walking, no phone. That's Zone 2 cardio, daylight exposure, stress reduction, and relationship building in one overlapping hour. It's also the thing I'd regret missing if I skipped it for "a better workout."
4. Handling dental and vision like they matter. Most men my age blow these off until there's a problem. The dental cleanings every six months are non-negotiable. The eye exam is on the calendar. This is the boring blocking and tackling that nobody writes essays about, and it's exactly why you should do it.
I'm not optimizing for performance anymore. I'm optimizing for presence. I want to be in the room. I want to be able to pick up a 3-year-old toddler. I want to be the grandfather I didn't get to have. That's the target. Everything else is noise.
What the longevity industry gets wrong
Most longevity content is written for an audience that's bored. Rich, optimized, has already solved the basics, and is looking for the next 2% edge. The peptides. The cold plunge. The thing that costs $8,000 a month and gives you a 0.3% improvement in some biomarker nobody can explain.
That's the wrong audience for most of us. If you're 50 and you've got back pain and you're not sleeping enough and your default meal is grabbed in a cab, you don't need peptides. You need sleep, strength, protein, sunlight, and a doctor who will tell you the truth. That's 95% of the gain for 5% of the cost.
The Peter Diamandis abundance thesis — that we're heading toward a world where 100 will be the new 60 — is exciting. I want that world for a 3-year-old toddler. But I don't want to wait for it. I want to do the boring basics now so that when the technology arrives, my body is still in shape to receive it.
The challenge
Here's what I'll leave you with: If you knew you had 20 good years left — 20 years where your body still worked well enough to do the things you love — what would you stop doing this week?
Most people I've asked have an instant answer. Stop drinking every night. Stop skipping sleep. Stop eating like you're 28. Stop saying yes to the thing that makes you travel a week you didn't need to travel. Stop carrying the 15 pounds that showed up during COVID and never left.
If you have the answer, you already know what to do. The question is whether you're going to do it this week or keep putting it off. My child doesn't care what my cholesterol is. He cares whether I can chase him in the park. Those two things are more related than I used to understand. That's the discipline I'm running now. It's not easy — but the alternative is worse.
