The strangest thing happened when I turned 50.
I’d spent twenty-three years rebuilding broken nervous systems. Children with cerebral palsy, autism, spinal cord injuries — bodies the medical establishment had quietly given up on. I learned to find what still works, to build from that, to be patient with biology. I watched kids walk who weren’t supposed to walk.
I thought I understood the human body.
Then my own body started doing things I didn’t have a good answer for.
Not dramatically. Nothing collapsed. It was quieter than that — the kind of slow drift that’s easy to explain away. Recovery taking a day longer than it used to. The mental clarity that used to show up at 6am arriving at 10. Lab numbers that were “within normal range” but trending in a direction I didn’t like. And the thing I noticed in my andrology practice every single week: men my age coming in for one problem, and leaving with a conversation about five others they hadn’t connected yet.
Testosterone. Sleep. Inflammation. Cognitive performance. Energy. These aren’t separate departments. They’re the same building losing heat through every wall simultaneously.
I’m an andrologist. I’ve been treating male reproductive and hormonal health for over two decades. I’ve watched what happens to men who ignore the intersection of metabolic health and sexual health in their fifties. The consequences are serious, measurable, and — this is the part that still surprises patients — largely preventable.
But here’s what my double career taught me that most longevity content misses:
The body responds to input. At any age.
I’ve watched a non-verbal eight-year-old with severe hypotonia learn to use his hands because we gave his nervous system the right stimulus, consistently, over time. The mechanism is different at 56, but the principle is identical. Biology is not a death sentence. It’s a negotiation.
What I actually do on this site
I test things on myself. Blood panels before and after. Sleep tracking. Genuine protocols, not theory. When something doesn’t work — or works differently than the research suggested — I say so.
I read primary literature. Not health journalists summarizing summaries. I’ve been parsing clinical studies for twenty-three years. I know what a sample size of forty-two men over eight weeks actually tells you, and what it doesn’t.
I bring an andrologist’s lens to longevity. That means I don’t separate hormonal health from cognitive health, sexual health from metabolic health, or muscle from mind. In my clinic, I’ve never seen these things exist in isolation. I won’t pretend they do here.
And I bring a rehabilitation specialist’s patience. I have watched the slowest possible biological progress and learned not to panic, not to chase hacks, not to confuse noise for signal. The research on longevity is genuinely exciting right now. It’s also full of products that are twenty years ahead of the evidence. I’ll tell you which is which.
A note on trust — because this is health information
I’m a physician. Nothing on this site is your personal medical advice. Some of what I write about — particularly pharmacological interventions like metformin or peptide therapies — requires a doctor who knows your specific history. I’ll always tell you when you need one.
I’ll also tell you when I have a commercial relationship with a product. Every affiliate link is disclosed. I’ve declined partnerships with three supplement companies in the last year because I didn’t believe in what they were selling. The ones I recommend are ones I use, have tested, and would recommend to a patient.
Everything here is reviewed by me. When I cite a study, I’ve read it, not a summary of it.
The thing about being 56
I’m not writing to you from some imagined future where I’ve figured everything out. I’m 56. I’m in the middle of this.
My practice is full of men who waited until their bodies announced a problem before they paid attention. I don’t want to be that story, and I’m guessing you don’t either. That’s why I’m here, and that’s probably why you’re reading this.
Let’s figure out the second half together.
