Disclaimer

Biological age is an estimate based on lifestyle factors and is not a medical diagnosis. True biological age measurement requires clinical biomarkers such as DNA methylation, telomere length, and blood panels. This quiz provides a general indication of how your habits may influence your rate of ageing. Use it as motivation, not as medical advice. Always consult a healthcare professional for personalised health assessments.

Frequently Asked Questions

What is biological age?
Biological age measures how well your body functions compared to average for your chronological age. Someone who is 50 but exercises regularly, sleeps well, and manages stress might have a biological age of 42, meaning their body functions like a typical 42-year-old.
How accurate is this calculator?
This is a lifestyle-based estimate, not a clinical measurement. True biological age testing uses biomarkers like DNA methylation, telomere length, or blood panels. This quiz provides a directional estimate based on factors strongly correlated with biological ageing in research.
Can I lower my biological age?
Yes. Research shows that regular exercise, quality sleep, stress management, a healthy diet, not smoking, moderate alcohol intake, and strong social connections can all slow biological ageing. Some studies show measurable biological age reversal with sustained lifestyle changes.
What factors most affect biological age?
The biggest modifiable factors are: regular exercise (especially both cardio and strength training), sleep quality and duration, diet quality, stress management, not smoking, and social connection. Genetics play a role but lifestyle factors are highly influential.
