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.

Article: A few weeks ago, a friend of Smile Groups gifted me PS100 to do good deeds with. Since then I have used the money in the U.K. and the U.S and have helped some strangers, generally raising a lot of smiles. They have warmed my heart, but none so much as the gift I was able to give just an hour ago. I was in a shop looking at the second-hand books. It just so happened that the bookshelves were next to the toy section. After a few minutes I became aware of a group of women standing behind me. They were poorly dressed and spoke in what sounded like an eastern European language. As the little girl, about three years old, came over to the toy section, immediately her attention was caught by a toy. She spoke to her mother and in halting English her mother asked the shop assistant how much it cost. PS3 was the answer. The mum looked down at her child, perhaps calculating what she still had to buy and how much money she would have left. Then she simply shook her head. The child didn't react badly as some children might. Being told no was obviously not a new experience for her. But she couldn't keep the disappointment from her face. I had the total of four pounds in my pocket, two PS2 coins. A moment later, I tapped the mother on the shoulder, and pointed to the coins which I had left and said, "Buy her a dolly, too." I didn't hang about to see the end result. _ . I made my way out of the shop and into the sunshine. The money my friend gave me was an investment in the happiness of the world. Was there any better way, I wondered, to get so much happiness with so little money than to buy a toy for a little girl?
