Article: Older fathers have uglier children, researchers have claimed after linking age to genetic mutations . The finding comes weeks after leading scientists reported children born to men over the age of 45 run a higher risk of having autism and mental disorders. With age, sperm -producing cells do not copy a man's DNA as effectively, leading to genetic mutations. Martin Fielder, an anthropologist at Vienna University, told the Sunday Times: 'Every 16 years the mutation rate doubles. Other researchers found 25 mutations per sperm in a 20-year-old, but at age 40 it is 65 mutations. By 56, it doubles again. The effect is very visible - someone born to a father of 22 is already 5-10 per cent more attractive than those with a 40-year-old father and the difference grows with the age gap. In contrast, women pass on a maximum of 15 mutations to their baby, regardless of age, according to the study published in the journal Nature. Surveying a group of six men and six women, researchers showed them each 4,018 photographs of 18-20-year-old men and 4,416 of women the same age, and asked to assess their attractiveness. Those with older fathers were consistently considered less attractive. However, the children of older men, though less attractive, are likely to outlive their peers with younger fathers, it is claimed. Professor Lee Smith, a geneticist at Edinburgh University, told the Sunday Times other research found such children have longer telomeres - the caps on the end of chromosomes --- which are associated with longer life. But the mounting research connecting parents' age with autism is cause for concern, experts warn. Autism is an umbrella term for a range of developmental disorders that have a lifelong effect on someone's ability to interact socially and communicate openly. In the UK, around one in 100 adults is thought to be affected by autism, mostly men, caused by a combination of genetic and environmental factors. Researchers said men should be advised about the potential problems in order to help their personal decision-making when it came to having fathering children at older ages. They warned that advancing paternal age faced a risk of 'numerous public health and societal problems'. Among well-known older dads are Simon Cowell, 54, whose son was born earlier this month, and comedian Frank Skinner whose first child was born in 2012 when he was 55.
Answer: When a man becomes older, sperm-producing cells copy his DNA less effectively

Article: When my grandfather died, my 83-year-old grandmother, once so full of life, slowly began to fade. No longer able to manage a home of her own, she moved in with my mother, where she was visited often by other members of her large, loving family. Although she still had her good days, it was often hard to arouse her interest. But one chilly December afternoon three years ago, my daughter Meagan, then eight, and I were visiting her, when she noticed that Meagan was carrying her favorite doll."I, too, had a special doll when I was a little girl," she told a wide-eyed Meagan. "I got it one Christmas when I was about your age. I lived in an old farmhouse in Maine, with Mom, Dad and my four sisters, and the very first gift I opened that Christmas was the most beautiful doll you'd ever want to see." "She had an exquisite(,), hand-painted face, and her long brown hair was pulled back with a big pink bow. Her eyes were blue, and they opened and closed. I remember she had a body of kidskin, and her arms and legs bent at the joints." GG's voice dropped low, taking on an almost respectful tone. "My doll was dressed in a pretty pink gown, decorated with fine lace. ... _ -- my parents must have had to sacrifice so much to afford it But how happy I was that morning!" GG's eyes filled and her voice shook with emotion as she recalled that Christmas of long ago. "I played with my doll all morning long. And then it happened. My mother called us to the dining room for Christmas dinner and I laid my new doll down gently on the hall table. But as I went to join the family at the table, I heard a loud crash." "I hardly had to turn around -- I knew it was my precious doll. And it was. Her lace skirt had hung down from the table just enough for my baby sister to reach up and pull on it. When I ran in, there lay my beautiful doll on the floor, her face smashed into a dozen pieces. She was gone forever." A few years later, GG's baby sister was also gone, she told Meagan, a victim of pneumonia . Now the tears in her eyes spilled over -- tears, I knew, not only for a lost doll and a lost sister, but for a lost time. Subdued for the rest of the visit, Meagan was no sooner in the car going home than she exclaimed, "Mom, I have a great idea! Let's get GG a new doll for Christmas. Then she won't cry when she thinks about it." My heart filled with pride as I listened to my sympathetic little daughter. But where would we find a doll to match GG's fond memories? Where there's a will, as they say, there's a way. When I told my best friends, Liz and Chris, about my problem, Liz put me in touch with a local doll-make. From a doll supply house I ordered a long brown hair and a kidskin body to copy the outfit GG had so lovingly described. Liz volunteered to put the doll together, and Chris helped me make the doll's outfit. Meagan wrote the story of the lost doll by giving examples. Finally our creation was finished. To our eyes it was perfect. But there was no way it could be exactly like the doll GG had loved so much and lost. Would she think it looked anything like it? On Christmas Eve, Meagan and I carried our happily packed gift to GG, where she sat surrounded by children, parents, aunts, uncles and cousins. "It's for you," Meagan said, "but first you have to read the story that goes with it." GG no sooner got through the first page than her voice cracked and she was unable to go on, but Meagan took over where she left off. Then it was time to open her present. I'll never forget the look on GG's face as she lifted the doll and held it to her chest. Once again her tears fell, but this time they were tears of joy. Holding the doll in her frail arms, she repeated over and over again, "She's exactly like my old doll, exactly like her." And perhaps she wasn't saying that just to be kind. Perhaps however impossible it seemed, we had managed to produce a close copy of the doll she remembered. But as I watched my eight-year-old daughter and her great-grandmother examining the doll together, I thought of a likelier explanation. What GG really recognized, perhaps, was the love that inspired the gift. And love, wherever it comes from, always looks the same.
Answer: she was not able to live on her own due to her weakness
GG moved in with her daughter because _ .

Article: Every time you visit Disney World, there's something new to see. What began in 1971 as theprefix = st1 /MagicKingdomnow includes the high-tech, movie-mad Disney and Animal Kingdom. Each time the park expands, so do your chances to spend money. How can you save? As a family guide to Disney World, I've been to the park more than 25 times with my kids, and I've developed a few money-saving plans. * Buy the five-day All-in-One Hopper Pass . Even if you're visiting for fewer days, it's a deal (the pass costs $ 229 for visitors ages 10 and up, $ 183 for kids ages three to nine and is free for kids under age three). Without the pass, you'll have to pay separately for PleasureIslandand the water parks. A single trip toBlizzardBeach, for example, would cost a family of four $ 100. * Dine out at lunch. The prices at some of the nicer restaurants, especially those in Epcot's World Showcase, are much lower at noontime than at dinner. It's wise to make reservations before you leave home. Call 407-W-DISNEY. * Become a Gold Card Member. For $65, you can get a Magic Kingdom Club Gold Card (call 1-800-56-DISNEY). Card-holders get up to 20 percent off Disney hotel rooms, plus price breaks on character breakfasts, theme park tickets and goods from Disney stores. * Don't pay extra to see a character. Character-theme dinner shows are expensive, costing a family of four about $ 140, and even a character breakfast, where Mickey or Donald Duck joins you for cakes, can _ $ 50. If your budget is tight, try to meet the characters inside the theme parks and at free in-park shows. You can watch the Diamond Horseshoe show, for example, in theMagicKingdomfor no additional cost, while the similarly themed Hoop-Dee-Doo Musical Revue requires expensive tickets. * Wait until the end of your trip to buy souvenirs. By then, the kids will really know what they want, and you won't waste money on expensive things.
Answer: you should not buy souvenirs at the beginning of the trip
