2-Minute Quiz
Life Expectancy Test | Calculate Your Lifespan Score
Seven quick questions: your age and sex set a Statistics Canada baseline, then five habits linked to the longest lives in long-running Harvard cohort studies.
What this test measures
Your baseline is the average remaining life expectancy for Canadians of your age and sex, from Statistics Canada's 2020–2022 life tables. Your score counts how many of five low-risk habits you follow: never smoking, a BMI of 18.5–24.9, at least 30 minutes a day of moderate-to-vigorous activity, a high-quality diet, and low alcohol intake.
Those habits come from a Harvard study of over 123,000 US adults in the Nurses' Health Study and Health Professionals Follow-up Study (Li et al., Circulation, 2018). At age 50, women who followed all five lived about 14 years longer, and men about 12 years longer, than those who followed none.
How to read your result
The study compared groups, so it cannot say exactly how many years any one person will gain — your baseline is shown unadjusted, alongside your habit score. Note that the study counted moderate drinking as low-risk; this test uses Canada's 2023 alcohol guidance instead, where two or fewer standard drinks a week is low risk.
