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

Outside her cottage, old Mrs. Taylor was hanging out laundry on a wire line, unaware that some children were hiding in a nearby tree watching her every move. They were determined to find out if she really was a witch.
They watched nervously as she took a broomstick to sweep the dirt from her stone steps. But much to their disappointment, she didn’t get on the broomstick and fly off. The old lady only looked up when her hen began to make sounds loudly — signaling that she had laid an egg in the nest on the top of the haystack(干草堆).
The old lady put aside her broomstick and walked to the haystack, followed by Michael, a black cat she had rescued from a fox trap. With only three legs, it was hard for Michael to keep up with his mistress. The cat was proof for the children that only a witch would own a black cat with three legs! Crawling further along the branches, they could clearly see the haystack.
Mrs. Taylor was standing on a wooden box with the new-laid egg in one hand. Placing the egg in her pocket, she readied herself to climb down. Then, without warning, the box broke under her and she crashed to the ground. The children were in horror.
“Should we go and help her?” asked Mia.
“What if it’s a trick?” replied Patrick. “She probably knows we’re here. Witches know things like that!”
After thinking for a while, Julia said “Anyway, we should go and check whether she is all right.”
Approaching prudently, they could see a wound on the old lady’s forehead. She had knocked her head on a stone and was unconscious.
“Go and get Dad,” Mia yelled to her brothers. “Tell him about the accident.”
The boys didn’t need another excuse to leave. They ran as fast as they could for help, hoping that Mrs. Taylor would not regain consciousness and turn the girls into frogs.
Later, in the hospital, the old lady smiled her thanks. “I was so lucky that you lovely children happened to be passing when I fell. I must have yelled quite loudly.”
The children exchanged guilty glances, but were very pleased that she was not a witch after all!

“Never talk to strangers.” Many children are taught this simple rule as a precaution against abduction(诱拐). In June, 2005, an 11-year-old boy was lost in the Utah wilderness for four days. During that time, he stayed on the path. He saw people searching for him but deliberately hid from them, afraid someone might “steal” him. Eventually, the unfortunate game of hide-and-seek ended and he was found. According to the Canada Safety Council, this alarming incident shows how unwise it is to instill(灌输) a fear of strangers in children. The “stranger danger” message can prevent children from developing the social skills and judgment needed to deal effectively with real-life situations. In a difficult situation, a stranger could be their lifeline to safety.
To have a child go missing is a parent’s worst nightmare. The threat of abduction by a stranger is minimal when compared with other possible reasons for a disappearance. In 2004, there were 67,266 missing-children cases in Canada. Only 31 involved abduction; in most of those cases the abductor was a relative, friend, or person known to the family. There were 671 cases of children wandering off, and 332 cases of abductions by a parent. Almost 80 percent of all cases were runaways. These statistics cast doubt on the idea that children should never talk to strangers. Wandering off is more common — but a lost children may have to call upon a stranger for help, and must develop the ability to judge what kind of people to approach. The “never talk to strangers” rule does not protect children in the situations they are most likely to face. On top of this, it can be confusing. Adults do not model the behavior; they often talk to strangers. A child may not know how to tell who is a stranger, and who is not.
For young children, nothing replaces close supervision(监管). Pre-schoolers do not understand risk and tend to act without thinking. Children need to develop habits and attitudes that will protect them from the real threats and dangers they may face. The Canada Safety Council encourages parents to give their children age-appropriate positive messages about safety, bearing in mind how youngsters may understand their world.

Niagara Falls
The Niagara Falls consist of three sections. The large Canadian falls—with their distinctive curved shape—are also known as the Horseshoe Falls. They are separated by Goat Island from the American Falls, which are separated from the narrow Bridal Veil Falls by a small island at their south end. Each side of the falls offers a different perspective, and it is always best to visit both sides to maximize your experience.
Views of Niagara Falls are free and accessible. Access to the riverside walks and parks offer great views. You can walk across to Goat Island on the bridge on foot.
Cave of the Winds, ☎ +1 716 278-1730. Daily 9 AM-7:30 PM from Spring 2016. A lift takes you 175 feet down to a walkway that leads you right to the bottom of the Bridal Veil Falls. You will definitely get a feel for the true power of the falls! This is the closest you can get to the falls on either side without actually leaping into them! Raincoats and slippers are provided, and you will definitely need them. Adults: $12; 6-12 year: $8; younger children: Free, but must be 42 inches or taller.
Maid of the Mist. A boat ride, taking you down around the bottom of the falls. Some information is given about the falls, but the real experience is looking up at the falls from below and feeling the mist coming off the falls (hence the name). Wear a raincoat to avoid getting wet. Boats leave from both the American and Canadian sides, so you may want to check the exchange rates to see which will be more cost-effective when you visit! April-October.
The Niagara Gorge Discovery Center. Although it’s easy to enjoy the falls visually, the Discovery Center provides another way to appreciate the magnificence of the falls. Exhibits show the history of the entire area, including the falls, how they were originally formed, and how they've changed over time.
Aquarium of Niagara, 701 Whirlpool St, toll-free: +1 800-500-4609. 9AM-5PM. The aquarium at Niagara Falls. $10.

You can combine all these attractions with a Niagara USA Discovery pass for $35, which you can purchase at the attractions.
Must stay a night and see the night view of the Niagara Falls. It is equally beautiful.
During the winter season, a lot of repair work of the falls, tours, and surroundings takes place. Many areas, such as Terrapin Point and Luna Island, are closed due to slippery conditions. Winter brings a different kind of beauty to the falls and a visit during that time is certainly worthwhile, but if you want to experience the full range, plan to come in the warmer months.
