Old age may not sound exciting. But recent findings offer good news for older people and for people worried about getting older. Researchers found that people become happier and experience less worry after they reach the age of fifty. In fact, they say by the age of eighty-five, people are happier with their life than they were when they were eighteen years old.
The researchers asked questions about emotions like happiness, sadness and worry. They also asked about mental or emotional stress. They also found that levels of stress were highest among adults between the ages of twenty-two and twenty-five.The findings showed that stress levels dropped sharply after people reached their fifties.
The study also showed that men and women have similar emotional patterns as they grow older. However, women at all ages reported more sadness, stress and worry than men.
Researchers say they do not know why happiness increases as people get older. One theory is that, as people grow older, they grow more thankful for what they have and have better control of their emotions. They also spend less time thinking about bad experiences.
