Question 1

What is biological age?

Accepted Answer

Biological age is an estimate of how old your body appears to be functioning, based on measurable markers such as blood biomarkers, fitness, sleep and metabolic health — as opposed to chronological age, which simply counts the years since you were born. Two people born the same year can have biological ages a decade apart because habits and physiology differ.

Question 2

How do I lower my biological age?

Accepted Answer

You lower a biological age estimate by improving the inputs it measures: cardiorespiratory fitness, sleep duration and quality, metabolic markers such as glucose and inflammation, body composition, and stress load. The largest and fastest-moving levers for most people are regular aerobic training, resistance training twice a week, seven-plus hours of sleep, and reducing alcohol and ultra-processed food.

Question 3

Is there a free biological age test?

Accepted Answer

Yes. Aevon Health's Biological Age Calculator is free and produces a Levine PhenoAge-style estimate from standard blood panel values, and the free 3-minute Health Assessment produces a lifestyle-based estimate with no bloodwork required. Laboratory epigenetic clocks are the paid alternative and generally cost well over a hundred dollars per test.

Question 4

How accurate are biological age calculators?

Accepted Answer

Biological age calculators are estimates from statistical models, not measurements, so treat the number as a range rather than a fact. Blood-based models such as PhenoAge and laboratory epigenetic clocks correlate with health outcomes at the population level; lifestyle-based estimates are coarser but capture the behaviors you can change. All of them are far more useful as a trend over time than as a single reading.

Question 5

What is a good VO2 max for my age?

Accepted Answer

A good VO2 max is one that places you above the median for your age and sex, and an excellent one puts you in the top quartile. Because VO2 max declines with age, the target moves: what is average at 25 would be strong at 55. The practical goal for healthspan is to keep climbing percentile bands rather than to hit one absolute number.

Question 6

How much deep sleep do I need?

Accepted Answer

Most healthy adults spend roughly 13-23% of total sleep time in deep (slow-wave) sleep, which works out to about one to one and a half hours on a seven-to-eight hour night. Deep sleep declines naturally with age. Rather than chasing a wearable's deep-sleep minutes, the reliable route is to extend and stabilize total sleep — deep sleep largely takes care of itself.

Question 7

How can I improve my HRV?

Accepted Answer

Heart rate variability rises when parasympathetic recovery outpaces stress load, so the levers are sleep, alcohol, training load management, and daily breathing or relaxation practice. HRV is highly individual, so compare your values only against your own baseline — never against someone else's numbers.

Question 8

Which supplements are actually worth taking for longevity?

Accepted Answer

The supplements with the strongest human evidence base are the unglamorous ones: vitamin D where deficient, omega-3, magnesium, creatine, and protein if intake is low. Compounds marketed specifically as anti-aging — NR, NMN, resveratrol — have interesting mechanistic data but limited human outcome evidence. No supplement substitutes for sleep, training and nutrition.

Question 9

What is Aevon Health and how does it work?

Accepted Answer

Aevon Health is an AI-powered longevity and wellness platform. You complete a free 3-minute assessment covering nine longevity domains, and receive a Wellness Score, a biological age estimate and a Health Blueprint preview. Aevon Pro unlocks the full AI toolkit — meal planner, fitness planner, lab and biomarker analyzer, supplement stack builder, sleep protocol, stress and recovery protocol, biomarker targets and the full Health Blueprint.

Question 10

How much does Aevon Pro cost?

Accepted Answer

The Aevon Health assessment, results and free tools cost nothing and require no card. Aevon Pro is a paid subscription that unlocks the full AI toolkit; current pricing is listed on the pricing page, and every Pro plan is covered by a 7-day money-back guarantee. Subscriptions can be cancelled at any time and access continues to the end of the paid period.

Question 11

What does an AI health assessment actually measure?

Accepted Answer

An AI health assessment measures self-reported inputs across health domains — sleep, nutrition, movement, stress, energy, substances, body composition and history — then uses models to score them, estimate risk-relevant summaries such as biological age, and rank which changes are likely to matter most for you. It does not measure physiology directly and cannot detect disease.

Question 12

What is the best diet for longevity?

Accepted Answer

No single named diet wins. The patterns associated with the longest healthspan in observational research share the same features: mostly whole plants, adequate protein, healthy fats, high fiber, minimal ultra-processed food, limited added sugar and limited alcohol. Mediterranean-style eating is the best-studied version of that pattern, and adherence over years matters more than the label.
