For most of my adult life, I was told what I couldn't do. By doctors, by specialists, by a body with 360,000 lifetime dislocations and a pharmacological profile that should have killed me.

In 2019, I faced a binary choice: stop all the opiates — fentanyl, methadone, morphine, OxyContin — or don't make it to the following year. The detox took 256 days. I came out the other side with better pain control than any medication had given me.

I have classical Ehlers-Danlos Syndrome. Severe global dysautonomia including structural baroreflex failure. Complete gastrointestinal dysmotility — which means no oral medications, ever. Chronic pain managed without analgesia since 2019. Narcolepsy. Coronary heart disease.

In under two years at 58, I took my VO2 max from 30 to 55. My resting blood pressure from 198/141 to 108/61. I've ridden over 6,000 miles since my first year on a bike in 2023 — a year I began rebuilding my legs from scratch.

The medical system failed me for decades. Cycling didn't. That is not a motivational statement. It is a physiological fact that I spent years reverse-engineering.

Pain is my operating environment, not my enemy.


Prosthetic
Physiology

A six-component self-developed framework that replaces the autonomic functions my body can no longer perform reliably. This is not a mindset. It is architecture — systems thinking applied to a broken physiological stack.

What I've built isn't willpower. It is engineering around the gaps: anticipatory cognition replacing absent reflexes, mechanical motion substituting for a circulatory system that doesn't self-regulate, and data replacing symptom signals I simply do not receive.

"Not willpower. Architecture. I do not trust how I feel. I trust the numbers."

VO2 max progressed from 30 to 55 in under two years at age 58. Active self-management across five 24-hour blood pressure monitoring cycles reduced time above symptom threshold by 42% without pharmacological intervention. The framework is the mechanism.

01 — COGNITIVE

Anticipatory

Anticipatory decision-making replacing absent autonomic reflexes. I do not rely on symptoms as warning signals — they either don't arrive or arrive too late to be useful.

02 — MECHANICAL

Continuous Motion

Cycling as circulatory and muscle-pump substitute. Stillness is a haemodynamic gamble. Motion is the intervention.

03 — TEMPORAL

Precision Timing

Precision scheduling of effort, rest, nutrition, and heat exposure within defined physiological windows. Timing is not a preference; it is a load-bearing component.

04 — NUTRITIONAL

Controlled Infusion

Micro-feeding as controlled infusion. GI absorption is unreliable. Fuel is managed to prevent haemodynamic shocks and circulatory collapse mid-effort.

05 — ENVIRONMENTAL

Active Regulation

Heat, cold, posture, and compression as active regulatory tools. The environment is not a backdrop — it is part of how I regulate blood pressure, circulation, and nerve function.

06 — DATA

Signal Hierarchy

HRV, heart rate, and trend patterns replace subjective sensation. Internal somatic signals take priority for real-time decisions. Instruments validate and contextualise.
