Researcher Albin Dahlin Almevall has looked at what factors from the age of 60 can be linked to whether you are still alive and how you feel.
About 500 people in Norrbotten and Västerbotten have received home visits where he has asked about well-being, taken blood samples and measured bone strength as well as memory tests.
"We can see that certain factors can be linked to healthy ageing. And what's interesting is that we can influence many of these ourselves," says Dahlin Almevall.
In the video, he talks about the factors of a good life at 80.
