Older people are more optimistic than young people

Older people often look at the cup half full, rather than half. This is because they have accumulated a lot of experience in life and also derived from the biological changes brought about by old age.

Researchers gave 20 young people between the ages of 19 and 22 to see positive, neutral and negative photos, such as a cup of chocolate ice cream, a power board and a dead animal. Another group of 20 people aged 56 to 81 also saw such pictures.

Electrodes on participants' heads will record brain activity when they view these images. Increased levels of brain activity will reflect each individual's reaction to negative information.

The results show that older people have less reaction to images that are not more beautiful."In general, older people are less prone to depression and less affected by negative information , " said Stacey Wood, a neurologist at Scripps University in Claremont, California, USA.

Wood explained, usually, when it comes to making decisions, people often weigh twice as much."For example, when deciding when to gamble, losing $ 100 will be twice as heavy when eating $ 100. In general, everyone is programmed to pay more attention to negative information. " Wood said.

This trend will decrease with old age. It is unclear why older people tend to look at life through a pink lens. Maybe it was because of the experiences they gained or the biological change of old age.

Another study also found that older people see better panoramas than young people. And optimists also live longer.
