so does happiness equal money and good health? Not according to the artist Erik Krikortz. He feels that there are other ways of measuring happiness. Krikortz has a website and visitors click on different happy or sad faces to comment on how well they sleep, their family and friends, their level of stress, their inspiration and their physical activity. When you finish, his website adds the results for each area and it gives you a final result for your happiness in his home city of stockholm, Krikortz also shows the results of his survey as different coloured lights on the side of a large building in the city. For example, red means the people of Stockholm are very happy, green is ok and purple means many people are sad. 'A lot of people look at the building every day and see how"we" are," Krikortz says The coloured lights are also useful if you feel like visiting the city For example, if the lights are red, you know the locals are feeling happy!
