The older you are, the happier you are

Livescience said Gallup interviewed more than 340,000 Americans by phone since 2008 to explore factors that lead to differences in people's feelings of happiness.

After analysis, the experts found that the feeling of happiness changes with age. This result is consistent with many previous studies.

However, Gallup experts find happiness in two aspects: long-term and daily.

Emotional states that affect the feeling of daily happiness - such as anxiety, excitement, stress, sadness, anger - change over time, but follow different patterns. For example, stress and anger diminish teenagers until they are old. But anxiety remains almost the same until age 50. The level of sadness gradually increases until the early years of your forties and decreases as people enter the middle years of their fifties.

The happiness of men and women changes the same over time, although women tend to suffer higher levels of stress, anxiety and sadness. However, women's satisfaction level is equal to that of men throughout their lives. For the first 50 years of life most women feel happier than men.

'Our research shows emotions related to the level of daily happiness - especially negative emotions - different transformations as our age increases' , Arthur Stone, a member in Gallup's research team, said. Stone is a psychologist at Stony Brook University, speaking.

There are many theories proposed to explain why people feel more satisfied with life. For example, some scientists believe that older people control emotions better than young people. Another hypothesis says that when human age increases, our negative memories decrease, so that we feel more satisfied with life.

Also, according to Stone, when entering the age of people, people no longer focus on ambitions or achievements. Instead, they are only interested in how to make good use of the rest of their lives.
