Longevity Blog
Practical, evidence-based articles on the habits, metrics, and everyday choices that shape how long — and how well — you live. Each one ties back to a question we ask in the AgeAi assessment.
Why a lower resting heart rate is one of the simplest signals of cardiovascular fitness — and what your number actually means.
Your smartwatch measures it every night. Here's what heart rate variability actually reflects about your recovery and resilience.
Grip strength is one of the strongest predictors of healthy aging researchers have found. Here's how to test — and improve — yours.
Sleep is one of the most underrated longevity habits. Here's how much you actually need — and why consistency matters as much as duration.
Loneliness carries a mortality risk comparable to smoking. Here's what the research says about relationships and lifespan.
Muscle mass declines with age unless you train against it. Here's why resistance training is one of the highest-leverage longevity habits.
Ultra-processed food and excess sugar drive measurable biological aging. Here's how — and simple ways to cut back.
Chronic stress does more than feel bad — it drives real biological wear. Here's what's actually backed by evidence.
High blood pressure has no symptoms but drives heart disease, stroke, and kidney damage over decades. Here's what your numbers actually mean.
The science on moderate drinking has shifted. Here's what current research actually says about alcohol, aging, and how much is "safe."
Even daily exercisers face higher mortality risk if they sit for most of the day. Here's the research on sedentary time — and how to break it up.
A landmark study linked hydration habits to biological aging markers. Here's what the research shows — and how much water you actually need.
Eating late at night disrupts metabolism and sleep, independent of what's on your plate. Here's what the research on meal timing says.
Most life-threatening conditions are far easier to treat when caught early. Here's why routine screenings are one of the highest-leverage longevity habits.
Education is one of the most consistent predictors of lifespan in population research. Here's why — and how to build the same benefits at any stage of life.
Falls are a leading cause of injury-related death in older adults, and balance starts declining decades before anyone notices. Here's how to protect it early.
People who walk or cycle to work show consistently lower rates of heart disease and early death. Here's why active commuting outperforms gym-only exercise.
Cardiorespiratory fitness is one of the strongest predictors of mortality ever studied — stronger than smoking or cholesterol. Here's what it is and how to raise it.
