Based on your age, gender, and lifestyle habits — how long are you likely to live, and how much time do you have left?
Life expectancy is a statistical estimate based on population-level data. We start with the average life expectancy for your country and biological sex, then apply adjustments based on lifestyle factors that research has shown to significantly impact longevity. These include smoking, exercise, diet, sleep, alcohol consumption, stress, and social connection.
Research consistently shows that smoking is the single largest modifiable risk factor for early death, reducing life expectancy by an average of 10 years. Regular exercise, good sleep, and strong social connections are among the most powerful positive factors — each associated with several additional years of life.
Loneliness has been described by researchers as a public health crisis. Studies show that strong social relationships are associated with a 50% increase in survival odds — an effect comparable to quitting smoking. Isolation, by contrast, is associated with a significantly shorter lifespan.
Absolutely. While genetics play a role, research suggests that lifestyle factors account for the majority of variation in lifespan. The good news is that many of the most impactful changes — quitting smoking, exercising regularly, improving sleep — are within reach for most people.
