## What the Reel claims
The clip presents Dr. David Sinclair talking about testing and optimizing a longevity protocol, saying he is 56 with few wrinkles/no grey hair/good eyesight, and that his 86-year-old father is doing well. It links those observations to exercise, diet, metformin and resveratrol/NMN-style supplement routines.

## Evidence label
Sinclair is a real Harvard aging researcher, and the biology around NAD+, sirtuins, metformin, exercise and inflammation is real research. The weaker part is translating one researcher/family routine and biomarkers into a proven public longevity protocol.

## Safe conclusion
Exercise, avoiding smoking, limiting alcohol, sleep, diet quality and weight/metabolic health remain the strongest practical healthy-aging foundations. Metformin, NMN and resveratrol are active research or supplement areas, but no pill/supplement stack has proven in randomized human trials that it slows aging or extends lifespan in healthy adults.
