Discover your biological age.
Your calendar age counts the years you've lived. Your biological age reflects how fast your body is actually aging — shaped by your metabolism, movement, sleep, stress and habits. Two people born the same year can be a decade apart.
Answer a few questions about your lifestyle and health. We'll estimate your biological age, show you what's adding years, and tell you what to change first.
We'll email your full report. No spam, unsubscribe anytime. Educational estimate, not a medical exam.
What is your biological sex?
We use this only to apply the right reference ranges.
When were you born?
What are your height and weight?
What is your waist measurement? (optional)
Measure at the level of your belly button. Waist-to-height ratio is a stronger risk signal than weight alone. Skip it if you don't know.
Are you currently taking a weight-loss medication?
How many steps do you take on a typical day?
Your phone or watch usually has this number.
How many hours of exercise do you get in a typical week?
Anything that raises your heart rate: brisk walking, running, cycling, swimming, gym cardio or sports.
How often do you do strength training?
Weights, resistance bands, bodyweight exercises or a strength class.
How do you feel after climbing two flights of stairs?
A simple, reliable read on your cardiorespiratory fitness.
What is your resting heart rate?
Your watch or phone usually shows it. If you don't know, choose "I don't know".
How many nights a week do you get 7 or more hours of sleep?
How often do you wake up feeling rested?
How would you rate your stress in a normal week?
How would you describe your energy on a typical day?
How is your sexual health lately?
Erection quality is one of the earliest indicators of blood-vessel health. Only your physician reviewer sees this answer.
How would you describe your menstrual cycle and hormonal health?
This sets your reference ranges and shapes your protocol. Only your physician reviewer sees this answer.
How many servings of vegetables or fruit do you eat a day?
One serving is roughly the size of your fist.
How often do you eat fast food, sweets or sugary drinks?
How many glasses of water do you drink a day?
Plain water only — coffee, tea and soft drinks don't count.
How many alcoholic drinks do you have in a typical week?
Do you smoke or vape?
Do you know your blood pressure?
Has a doctor ever diagnosed you with any of the following?
Select all that apply.
Has anyone in your immediate family — parents, brothers or sisters — had any of the following?
Select all that apply. Family history helps us weigh your genetic risk.
Do you take any of these medications regularly?
Prescription medications only. Select all that apply — your physician reviewer needs this.
When was your last comprehensive blood test?
A full panel — cholesterol, glucose, hormones — not a quick finger-prick.
