I was driving home the other day on a sunny afternoon. I had a smile on my face as I sang along to the songs on the radio. It was such a beautiful day that I felt full of happiness. My good mood ended, however, when the radio station took a news break between songs. Then suddenly I found myself listening to yet another story of a rich famous man who had broken the law. I shook my head as I came to a red traffic light.

As I pulled to a stop I noticed four leather?jacketed bikers. They were standing in the middle of the road with two on either side of the light. They looked rough and dangerous, but as I got closer I noticed each one was holding their helmet in their hands. I rolled down my window as one approached my car. “We are the Brother of the Wheel，” he said. “We are collecting money for Christmas Toy Drive for needy children.” As I pulled a dollar out of my wallet I looked past his beard and into his eyes. They shined with goodness and kindness that came right from his soul. I dropped the money in his helmet and waved to the other bikers as I drove off. My good mood had returned. My faith in mankind had been bolstered. And I remembered once again never to judge people by their appearance.

Our society often judges books by their covers but God reads what is written in our hearts and souls. Perhaps one day we will all learn to see the world through the same eyes. Perhaps one day we will realize that looks matter little and actions matter much.

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.
