Blood pressure could certainly be an indicator of one's happiness. Researchers at the University of Warwick have found a direct connection between a nation's overall happiness and its citizens' blood pressure problems.
They drew a random sample of 15,000 people from across the European countries.
These people were asked how happy they were, whether they had had problems of hypertension (high blood pressure) and so on.
While Sweden, Denmark and the United Kingdom come top of this blood-pressure-based happiness league, Germany, Portugal and Finland are at the bottom of the heap.
The researchers believe that it could offer a way for policy makers to move away from simply focusing on maximising its Gross Domestic Product.
University of Warwick Economist Professor Andrew Oswald who, along with David Blanchflower of the Dartmouth College, USA, conducted the study, said: "We found that a measure of a nation's rate of hypertension is a good predictor of its overall happiness. In course of time blood-pressure readings may replace GDP as a measure of the success of a country. At any rate BP will be an additional criterion."
He hoped that one day economists and doctors would work together in the design of economic policies.
