Platelet count: 8 (Normal: 150-400) - Doctors said they had no options left
How a near-fatal snake bite destroyed my body—and the longevity protocols that brought me back to life
April 10, 2024. 2:00 PM. Santa Barbara Mountains.
It was the first hot, sunny day after months of cold weather—90 degrees and perfect for trail running. I'd been training in these mountains for years, knew every turn, every climb. My heart rate would hit 200 BPM at the steepest section, right where an old tree marked my favorite spot to pause and check my pulse.
I was three steps away from that tree when everything changed.
The Strike
A rattlesnake exploded from the bush to my right.
Time stopped. The world shifted into slow motion. I watched—with strange, detached clarity—as the snake's open mouth flew toward my left leg, venom dripping from its fangs like liquid death.
This is going to be bad, I thought.
The snake's teeth sank into my calf. Its body clung there for what felt like an eternity, until my right foot instinctively kicked its head. It disappeared back into the brush as quickly as it had appeared.
My heart was still thundering at 200 BPM. I looked down. Blood streamed from two perfect puncture wounds.
I had a choice, or at least I thought I did. My first instinct was to make it to my car—12 minutes of running downhill—and drive myself to the hospital. But something deeper, a gut feeling I'd learned to trust over decades, told me to call for help first.
I called my best friend, someone who'd dealt with rattlesnakes extensively. Fortunately, he picked up immediately.
"Call 911. Now," he said, his voice urgent. "Don't try to drive yourself."
That call saved my life.
A few steps later, I saw something shining through the blood on my calf. It was a fang—stuck inside my leg. I pulled it out and threw it away, then immediately regretted not keeping it as a souvenir.
A few minutes after the bite, I could feel the venom entering every cell of my body with lightning speed. The 911 operator kept telling me to sit down and calm down, but I knew if I sat down I wouldn't be able to get up. My innate intelligence told me to keep running.
A metallic chemical taste filled my mouth—the taste of venom coursing through my bloodstream. That taste would stay with me for the next seven days.
When "Experts" Don't Believe You
By the time I reached my car, I could barely speak. My body was shutting down, going into paralysis from the inside out. Two ambulances arrived—eight emergency medical technicians in total.
Not one believed I'd been bitten by a snake.
"Are you sure you got bit?" they kept asking, even as blood ran down my leg, even as I pointed to the fang marks, even as my mouth stopped forming words.
By the time I reached the hospital, I was completely paralyzed. I couldn't move my fingers. Couldn't move my tongue. Couldn't speak at all. My wife was crying, terrified. The paralysis lasted for hours.
It took nearly three hours for them to prepare the antivenom. Through my completely paralyzed state, I heard emergency nurses asking repeatedly, "Why didn't the EMTs call ahead so we could have the antivenom ready?" The communication failure had cost precious time—time my body didn't have.
The first dose of Crofab finally brought me back from complete paralysis. Slowly, painfully, I could move my mouth again, whisper to my wife that I'd be okay.
I wasn't okay.
The Descent
They placed me in the surgical department—their primary concern was preventing amputation, not treating the systemic venom damage. That first night, the pain was excruciating—unlike anything I'd ever experienced. When I asked for help, the resident doctor offered me Tylenol.
Tylenol.
For rattlesnake venom coursing through my system, destroying my blood from the inside out.
They released me the next morning. My platelet count was 70 (normal is 150-400). Still dropping.
The following day, I couldn't walk. We returned to the emergency room. Platelet count: 40.
They kept me for observation for two nights, then released me again. It was my wife's birthday. I pushed through excruciating pain to make it special for her, knowing something was terribly wrong but hoping my body would turn the corner.
That night, at midnight, a doctor called. My platelets had crashed to 8.
Eight.
At platelet counts below 10, spontaneous internal bleeding can occur. Your body can't clot. Any injury becomes potentially fatal.
Back to the hospital for the third time. This time, the Crofab wasn't working anymore. My veins had collapsed from repeated blood draws. The nurse kept missing them, which was especially dangerous when you can't clot.
The next morning, three doctors entered my room with the kind of faces that tell you everything before they speak.
"We've run out of options," they said.
I looked at them steadily. "So I should just go home and die?"
Silence.
My wife was in full panic. She immediately called my client's assistant, desperately searching for any way to save my life.
Saving My Own Life
I'd spent my hospital nights researching rattlesnake envenomation cases from around the world. I knew what they didn't: there was another antivenom—Anavip—and I needed a blood transfusion immediately.
"We don't have Anavip," they said. "And blood transfusions won't help."
My client—a high-profile individual I'd been training for years—made a call. Within hours, I was transferred to Cedars-Sinai in Los Angeles, one of the best hospitals in the country. They placed me in the oncology department, where the staff understood the complexity of blood disorders. They had Anavip. They understood what I needed.
The combination of blood transfusion and the new antivenom saved my life.
But that's when I discovered the real cost of survival.
The Body of an 80-Year-Old
When I finally left the hospital, in a matter of days my body's functionality had reached 80 years old.
I'm 58 years old chronologically. After the snake bite, my functional biological age had skyrocketed to approximately 80 years old.
I couldn't sweat. My grip strength had vanished. My cardiovascular resilience was gone. Simple movements felt like climbing mountains.
The venom had destroyed my cellular function. My mitochondria were damaged. My autonomic nervous system was compromised.
I had a choice: accept this as my new reality, or fight my way back.
I chose to fight.
The 12-Month Recovery Protocol
From the beginning, I implemented the complete longevity protocol—testing it under the most extreme conditions imaginable.
Weeks 1-4: The Suffocation Period
I couldn't sweat for weeks—a clear sign my autonomic nervous system was still severely damaged.
I started the full protocol immediately:
- High-intensity interval training (HIIT): Rebuilding cardiovascular capacity, even when my body felt suffocated
- Strength training: Restoring muscle mass (I reached 153 lbs grip strength by day 20)
- Hyperbaric oxygen therapy (HBOT): Flooding damaged cells with oxygen for mitochondrial repair
- Cold plunge + sauna contrast: Working to reboot my autonomic nervous system
- Red light therapy: Stimulating cellular energy production
The breakthrough came in week four. I sat in 200-degree sauna heat until my sweat glands reopened, no matter how long it took.
Forty-five minutes. That's how long it took before the first drops of sweat appeared. The next day, I sweated normally for the first time in a month.
Months 2-12: Complete Reversal
I continued the complete protocol with disciplined precision. Every session was measured. I tracked resting heart rate, heart rate variability, recovery metrics, grip strength, balance, endurance.
By month twelve, I retested my functional biological age using my comprehensive 11-part assessment.
My functional biological age: 31 years old.
From 80 to 31 in twelve months. A 49-year reversal.
What This Means for You
This journey proved something profound: your body's age isn't determined by time—it's determined by function.
When venom destroyed my cellular function, I functionally reached 80 years old overnight. When I rebuilt that function through targeted protocols, I reversed decades of biological aging.
The protocols that saved me:
✅ HIIT and strength training — Cardiovascular and muscular foundation
✅ Hyperbaric oxygen therapy — Deep cellular regeneration
✅ Cold/heat contrast therapy — Autonomic system rebooting
✅ Red light therapy — Mitochondrial recovery
✅ Precise measurement — Tracking progress objectively
These aren't just for surviving snake bites. They're for anyone wanting to reverse biological aging, recover from illness, optimize cellular function, and add quality years to life.
Measure Your Starting Point
The key to my recovery was measurement. I needed objective data at every stage.
That's why I created LongevityON—to provide access to the exact longevity tools that saved my life. The centerpiece is the LongevityON Biological Age Calculator: an 11-part assessment measuring cardiovascular resilience, strength, balance, grip strength, core stability, recovery capacity, and body composition.
The same tests that showed me at functional age 80 also proved my reversal to 31. Without measurement, you're guessing.

I was three steps from an old tree when a rattlesnake changed my life.
The venom nearly killed me. Medical negligence almost finished the job.
But the right protocols brought me back—and made me functionally younger than I've been in decades.
Your journey doesn't require a snake bite.
It requires the willingness to measure where you are and the commitment to do what it takes to get younger, stronger, and more resilient.
The snake taught me what I'd known intellectually but finally proved: functional biological age is a choice, not a sentence.
