Explore the biology of aging, from the hallmarks of cellular decline to what science suggests about extending healthspan alongside lifespan.
A fall can change the course of healthy aging, yet risk is often modifiable. The strongest plan looks beyond balance exercises to the full system that keeps a person steady.
Strength is essential for healthy aging, but daily life also demands the ability to produce force quickly. Muscle power connects laboratory capacity with real-world mobility.
Exercise is not one intervention with one effect. Aerobic capacity, strength, balance, and daily movement influence different parts of healthspan—and together help preserve independence.
Some adults over 80 retain memory performance comparable with people decades younger. New cellular research is helping scientists ask why—without yet providing a recipe for becoming a SuperAger.
Bones are living tissue, and fracture prevention begins long before a fall. Strength, nutrition, hormones, balance, and screening all contribute to skeletal resilience.
VO2 max is a useful window into cardiorespiratory fitness, but its greatest value comes from tracking capacity, function, and progress in context.
A single blood pressure reading is a snapshot. A well-collected series can reveal the average, day-to-day pattern, treatment response, and measurement noise that one clinic visit cannot.
Hearing is easy to treat as a quality-of-life issue only. Growing evidence connects hearing with social engagement, communication, function, and cognitive aging, while the landmark ACHIEVE trial adds important nuance.
The usual sleep question is, "How many hours did I get?" Emerging research suggests that the consistency of sleep timing may also carry useful information about long-term health.
A biological-age result can be an interesting snapshot, but healthier aging is better assessed through a portfolio of validated, repeatable measures tied to function and disease risk.
Several classes of therapeutic peptides are generating serious scientific interest as longevity tools, not because they stop aging, but because they target specific biological mechanisms that drive cellular decline.
You have one chronological age, but your biology may be younger or older than that number suggests. Understanding biological age, how it is measured, and what influences it opens a new window on personalized longevity.
Senescent cells are cells that have permanently stopped dividing but refuse to die. They accumulate with age and secrete inflammatory signals that contribute to tissue dysfunction and are now a major target in longevity research.
Chronic low-grade inflammation, now recognized as a hallmark of aging, is associated with virtually every major age-related disease. Understanding what drives it and what moderates it is central to longevity science.
Mitochondria are far more than cellular power plants. Their health, number, and efficiency are intimately connected to energy, inflammation, aging, and longevity and they are significantly modifiable through lifestyle.
In 2013, a landmark paper described nine cellular and molecular hallmarks of aging. Updated in 2023 to twelve, these hallmarks provide a biological framework for understanding why we age and where interventions may help.
Living longer is only part of the equation. Healthspan, the years lived with vitality, function, and quality, is the metric that most longevity science is now converging on.
