For 75 years, we've tracked the lives of 724 men, year after year, asking about their work, their home lives, their health, and of course asking all along the way without knowing how their life stories were going to turn out.
I 75 år fulgte vi 724 mænd, år efter år, spurgte vi ind til job, hjemmeliv og deres helbred og spurgte naturligvis dem alle løbende uden at vide hvordan deres livshistorie ville udarte sig.
