Cycling makes you happy.

Cyclists already know this and many other studies have shown that cycling helps to boost levels of seratonin and the extra sunlight will help vitamin D intake which both make you happier. The infographic above shows the correlation between bicycle sales in a country and the Satisfaction with Life score for that nation too. With the exception of the French, who never seemed to be satisfied, the more bicycles sold makes for a happier nation. 


Now it could be Denmark's strong social values, progressive tax model, fantastic welfare system and beautiful residents but I reckon it's probably all the cycling they do.
