Conventional wisdom says that hardship can make us old before our time. In fact, a new study suggests that violence not only leaves long-term scars on children’s bodies, but also changes their DNA, causing changes that are equal to seven to ten years of premature aging (过早老化).

Scientists measured this by studying the ends of children’s chromosomes (染色体), called telomeres, says Idan Shalev, lead author of a study published in Molecular Psychiatry.

Telomeres are special DNA sequences (序列) which prevent the DNA in chromosomes from separating. They get shorter each time a cell divides, until a cell cannot divide any more and dies.

Several factors have been found to shorten telomeres, including smoking, radiation and psychological stresses such as being treated badly when young and taking care of a chronically ill person.

In this study, researchers examined whether exposure to violence could make children’s telomeres shorten faster than normal. They interviewed the mothers of 236 children at ages 5, 7 and 10, asking whether the youngsters had been exposed to domestic violence between the mother and her partner, physical maltreatment by an adult or bullying. Researchers measured the children’s telomeres—in cells obtained from the insides of their cheeks—at ages 5 and 10.

Telomeres shortened faster in kids exposed to two or more types of violence, says Shalev. Unless that pattern changes, the study suggests, these kids could be expected to develop diseases of aging, such as heart attacks or memory loss, seven to 10 years earlier than their peers.

Shalev says there is hope for these kids. His study found that, in rare cases, telomeres can lengthen. Better nutrition, exercise and stress reduction are three things that may be able to lengthen telomeres, he says.

The study confirms a small?but?growing number of studies suggesting that early childhood hardship imprints itself in our chromosomes, says Charles Nelson, a professor of pediatrics and neuroscience at Harvard Medical School.

One day, when my wife and I were leaving a restaurant, I heard a man's voice from a car in the car-park. After a quick look at the car, I noticed the Pennsylvania license plate (牌照) at once, so I knew they had come from far away. The young man had his head partly out of the window and spoke to me as I moved closer, "Excuse me, my wife and I are trying to find a room for the night and every place in the area seems to be filled up. Do you have any suggestions for us where we might find a room?"

Well, that didn't surprise me. After all, it was the busy time of the year for tourism. As he spoke, I noticed that his wife was pregnant (怀孕的). I told them that they should just keep searching and wished them good luck in their search. The young husband didn't say any other words and backed out of the car-park and headed off. We also got into our car and drove home.

After a short drive, I couldn't get this young couple out of my mind. Here they were, traveling in a different state, tired, the wife pregnant. It was at that moment that my wife told me we needed to go back and find that couple. We went back and looked for them. We even went as far as the mountain.
