谁是最孤独的人群：老年人还是年轻人？
When we think of older people being more solitary, and thus more lonely, this might not actually be true. According to the survey of Julianne Holt-Lunstad, a psychology professor at Brigham Young University in Utah(犹他州), teenagers and young adults are more lonely than older people. Most of the time, teenagers and young adults always play with phones, but this is the expression of their loneliness. Holt-Lunstad and her colleagues analysed 70 studies, and found that there were stronger risks of illness about loneliness for under-65s than over-65s.
Also, the US National Social Life, Health and Ageing Project states that just 30% of older adults often feel lonely. While older people might be alone much of the time, this doesn’t mean they are unhappy about it.
In fact, people can feel lonely when they’re surrounded by others. Many lonely people are also married. Many people are accompanied by their families, but they also feel lonely. “Being unmarried is a significant risk,” Holt-Lunstad told the New York Times, “but not all marriages are happy ones. We have to consider the quality of relationships, not simply their existence or quantity.”
