How long might you live?

The five habits that made the biggest difference in a large US study: never smoked; a healthy weight (body mass index 18.5 to 24.9); at least 30 minutes of brisk activity a day; no heavy drinking (no alcohol, or no more than one drink a day for women, two for men); a healthy diet. We start with two ticked, the average adult. Change them to match you. These are averages for groups of people; they can't say how long you in particular will live.

How we work it out, and what this leaves out
How we work it out
We start from each country's published death rates by age and sex for 2019, the last year before the pandemic. These come from the World Health Organization.
Your habits move those rates up or down. In a study of about 120,000 US adults, people with all five habits had about a quarter of the death risk of people with none. We assume the average adult has two of the five. We weaken the effect after 65, because studies find smaller effects at older ages.
If you move, we blend the death rates of the two countries by the share you choose. The range shows the full spread, from none of the difference applying to all of it, plus 15% either way for what we don't know.
What this leaves out
Your own health, your family history, and the care you can reach near home. Air quality, road conditions and distance to a hospital also differ by city, and we don't model them.
Places called blue zones are not shown separately. Their records are disputed, and we found nothing showing they beat their country's average.
The habits effect comes from US health professionals, who are healthier than average. It may be smaller for other groups. Under 50, we apply the same effect, but most of the studies followed people from 50 on, so it is less certain for younger adults. Accidents and illness at younger ages also vary a lot by country.
