Biological age check: are your habits ageing you?
Your calendar says one age — what does the way you live say? Two people the same age can feel a decade apart — one springs up the stairs, the other aches getting off the sofa. A lot of that gap isn't the number on your birth certificate; it's the daily stuff: how you sleep, what you eat, how much you move, how heavy the stress sits. Take two private minutes to see whether your habits are quietly ageing you — and, more usefully, what's still in your hands to change.

What is a biological age check?
A biological age check on Nily is a short set of reflective questions about everyday habits — sleep, diet, stress, movement and smoking or alcohol. It organises those answers into a simple, directional impression of whether your lifestyle looks older or younger than your years. It is not a measurement of your cellular or medical biological age and not a diagnostic test.
Frequently asked questions
Is this a real biological age test?
No. A true biological-age measurement uses laboratory methods such as DNA-methylation “clocks” or other markers, done in a lab. This is a free, reflective check based only on the everyday habits you report. It gives a directional impression — whether your habits look older or younger than your years — and never a measured age. It cannot diagnose anything or replace a professional.
Is it free and private?
Yes — the check and your result are free, with no account and no card. Your answers produce a result in your browser; sensitive answers are never sold, sent to advertisers or used to build a marketing profile. Saving the result to track it over time is optional and happens in the Nily app.
Can it tell me how long I'll live?
No. Nothing here predicts lifespan, and any tool that claims to from a few habit questions is overreaching. Longevity is shaped by genetics, environment, medical history, access to care and chance — far more than a short quiz can see. The result is only a prompt to reflect on changeable daily habits.
My result said my habits look “older” — should I worry?
No — read it as information, not a verdict. It isn't a measurement and it can't predict your future. What's genuinely useful is that everything the check asked about — sleep, food, movement, stress, smoking, alcohol — is changeable. Pick the one that feels most doable and start there; the Nily app can help you track it.
What actually affects how we age?
Broadly, habits like sleep, physical activity, diet pattern, stress, and smoking or alcohol are commonly discussed alongside long-term health and how the body ages — but the size of any one habit's effect varies from person to person and isn't something a quiz can quantify. This tool keeps to that general, educational level and never claims a habit “adds” or “removes” a specific number of years.
