Cold & Heat Therapy: Temperature as Medicine
Ice baths, saunas, contrast therapy — the science of deliberate temperature exposure.
About This Quiz: Longevity
Longevity science has shifted from simply extending lifespan to maximizing healthspan — the years lived in good health, free from chronic disease and disability. Research from Blue Zones, twin studies, and cutting-edge molecular biology reveals that genetics determine only 20-25% of how long you live; the rest is lifestyle.
Understanding the 12 hallmarks of aging — from cellular senescence to mitochondrial dysfunction — provides a molecular roadmap for intervention. Each hallmark has modifiable risk factors, meaning that targeted lifestyle changes can slow biological aging regardless of your chronological age. The gap between your biological and chronological age is called your "aging rate" — and you can influence it.
