Eva Kerner, 71, a former secretary, has been retired since 2006 and goes to the gym twice a week ... attends concerts, visits museums, travels extensively, sings in a choir and is a prolific seamstress. It's a nice life," Kerner tells me. "Being so active keeps you young. I'm very happy." She's not alone. A study claims that retired Danish women are the most content in Europe, with those aged 65-74 scoring 8.6 out of 10 on the happiness scale - something experts suggest is partly down to the perspective that comes with age. But it's not just being over 65, female and busy that guarantees you a retirement of pure revelry. There's something about the experience of "living Danishly" that also helps. "Denmark is a country that takes care of its citizens," says retired associate professor Jette Eiberg, 71, from Copenhagen. "I feel very lucky to be here and I'm really grateful" - something else that has been proven to boost happiness levels. Sky-high taxes ... have the happy side effect of making Danes more content. Denmark has the lowest income inequality among all the OECD countries and studies show that living in neighbourhoods where most people earn about the same can make you happier. And because Denmark has one of the shortest working weeks at just 37 hours, Danes have plenty of time to foster friendships and extracurricular interests throughout their careers to see them through retirement.
