A comparison
David Sinclair describes the mechanisms inside the cell. MAVI describes the inputs the cell receives from the room. Two layers of the same biological stack.
The Sinclair research programme — sirtuins, NAD+, mTOR, epigenetic clocks — describes how the cell maintains and ages itself. The supplements, the caloric restriction, the cold exposure are inputs to those mechanisms.
MAVI describes a different set of inputs to the same cells: the air the lungs draw, the water the kidneys filter, the light the retina samples, the temperature the metabolism regulates against, the materials the skin contacts. The cellular and the architectural are different layers of the same stack.
| Sinclair (cellular) | MAVI (architectural) | |
|---|---|---|
| Subject | Cellular mechanisms of ageing. Sirtuins, NAD+ precursors, mTOR, AMPK, senescence, epigenetic clocks. The biology of cellular maintenance. | The environmental inputs to the same cells. Air, water, light, sound, temperature, materials, microbes, EMF — what the cells receive from the room. |
| Approach | Pharmacological / nutraceutical (NMN, NR, resveratrol, metformin, rapamycin) plus caloric restriction / fasting / exercise / cold. | Architectural specification of the residence the cells live inside. Specifies the exposure environment that supports or stresses cellular maintenance. |
| Time horizon | Decades. Cellular and epigenetic interventions show up in years, not weeks. | Decades. Architectural decisions, once specified, deliver across the life of the residence. |
| Where the leverage is | Inside the cell. Mitochondrial function, NAD+ pool, sirtuin activity, autophagy. | Outside the cell. The PM2.5 the alveoli draw, the PFAS in the bloodstream, the melanopic light that sets the circadian clock the cells answer to, the microbiome the immune system trains on. |
| What it cannot do | Cannot redesign the exposure environment producing the inputs the cells receive every breath, sip, and night. | Cannot replace the supplementation, the caloric restriction, the cellular-level intervention. Architecture and biology are different layers of the same stack. |
Sinclair specifies what the cell needs to maintain itself. MAVI specifies the residence whose architectural decisions determine what the cell receives every breath, sip, and night. Either alone is partial; together they describe the full longevity stack at cellular and architectural resolution.
