How important are our extraordinary experiences– like vacationing in Hawaii or watching the birth of kittens? The answer, according to researchers at Dartmouth College and the University of Pennsylvania, depends on how old we are. The Atlantic reports on a study, involving 221 people aged 18 to 19, that measured the happiness brought by extraordinary versus ordinary experiences simply by asking people. The researchers found that extraordinary moments always contributed strongly to happiness regardless of a person’s age, but older people felt that ordinary moments contributed to their happiness much more than younger people did. Older people saw ordinary moments as more self-defining than young people, and a perception of the future as limited led to a higher value placed on ordinary experiences. Read more in the Atlantic.
