Answer honestly — there are no right or wrong answers. Your results are calculated from your real responses and compared against longevity research benchmarks.
Sleep is the master lever of biological ageing. It affects every other KPI on this list.
Daily energy reflects mitochondrial health and metabolic efficiency — both core markers of biological age.
Cognitive performance is an early indicator of brain ageing. Lancet 2024: 45% of dementia cases are preventable.
Grip strength is one of the strongest predictors of longevity and all-cause mortality — better than BMI or cholesterol.
Resting heart rate is a direct window into cardiovascular fitness and autonomic nervous system health.
Visceral fat is more predictive of metabolic disease and cardiovascular risk than BMI alone.
Chronic stress accelerates biological ageing at the cellular level. Social isolation carries mortality risk equivalent to 15 cigarettes a day.
Muscle is the organ of longevity. It drives metabolic rate, injury prevention, and hormonal health into your 60s.
Recovery speed is a direct measure of systemic resilience and biological age.
