Healthspan, not just lifespan
Live long and live strong. The levers the research actually supports.
Healthspan is the number of years you live in good function, not just the number of years you are alive. The NIH National Institute on Aging, Peter Attia's research summaries, and The Lancet Healthy Longevity all point to the same levers: steady aerobic work, strength training, adequate protein, and sleep. Supplements and tests are secondary. This hub covers Zone 2, strength for aging, protein targets, blue-zones lifestyle patterns, and what the research actually supports versus what is marketing.
Longevity content is crowded with supplement claims. These guides are not. The levers that consistently appear in Nature Aging, The Lancet Healthy Longevity, Cell Metabolism, and work from the NIH National Institute on Aging are the boring ones: aerobic capacity, strength, protein, sleep, and social ties. Anything marketed as a shortcut around those is treated skeptically. This is lifestyle information, not medical advice.
