How much do we know about happiness? what does a human need to be happy? everyone answers this question in their own way but there also exists some objective data. a lot of people are sure that wealth is an important part of happiness and that money can make you feel on top of the world. actually, according to scientific research, money can’t buy you satisfaction. it is just getting the bare necessities that gives you a sense of delight. additional income can hardly raise your spirits. youth doesn’t make you happy either. the same research shows that older people are more satisfied with their lives than the young. in fact, young people tend to have dark moods and feel blue more often than senior citizens. a good education is a useful thing but, unfortunately, neither education nor a high iq1 is a key to happiness
