Finally, there is some good news for older dads. A new study shows that their children and even grandchildren may get a health benefit because of their older age. It's based on research into something called telomeres--tips on the ends of chromosomes      Some previous studies have connected having longer telomeres with better health and longer lives. Telomeres haven't been proven to cause those benefits in the general population, but a number of researchers think they may hold secrets for things like longevity and cancer.     As you age, telomeres shorten. However, previous studies have shown that the older a man is when he becomes a father, the longer the telomeres his children tend to have. The new research confirms that and finds it's extended to the grandchildren. That's a cheerier result for older dads than some other studies in recent years that indicate their kids are at higher risk for things like autism      Carol Greider of Johns Hopkins University, who shared a Nobel Prize in 2009 for telomere research but didn't participate in the new study, said it's no surprise that the telomere effect would extend beyond children to grandchildren. She also said that since older fathers also tend to pass more potentially harmful genetic mutations , it's "not at all clear" whether advanced paternal  age gives an overall health benefit to children. In a statement, the researchers who conducted the study said their study shouldn't be taken as a recommendation that men reproduce at older ages because there's a risk of genetic mutations.     Some previous studies of the impact of older fatherhood have been less encouraging. In 2010, for example, at least two big studies confirmed a link to having children with autism. In 2008, a big Swedish study strengthened evidence linking bipolar disorder  to older paternal ages. Which of the following statements about telomeres is NOT true? A) They are the tips on the ends of chromosomes. B) The older a man gets, the shorter they become. C) Some researchers have connected them to longevity and cancer. D) They have been proven to cause better health in the general population.

Honesty,my mum always used to tell me,is the best policy.Of course,this didn't include her when she told me that if I didn't eat all my vegetables Father Christmas would find out and wouldn't give me any presents. But when it comes to medicine.I had assumed it was important to always be honest with my patients.After all,the doctor-patient relationship is based on trust,and therefore honesty is essential.Or so I thought. I had just started working in geriatrics .Mr. McMahon was brought in when his belly was found very swollen.I took a medical history from his daughter who'd accompanied him in the ambulance.She'd been his main carer for years.I stood looking at him as she gave a detailed history."Has he lost any weight recently?"I asked."Well,it's funny you should mention that,but yes."she said slowly.There was silence for a few moments."Why? What are you worried about?"she asked.I hesitated.She was obviously very involved in his care and it was only fair that I told her the truth."Well.we need to prove it's not cancer."I said and talked briefly about some of the tests I was going to order. Half an hour later, a nurse called me:"Mr. McMahon's daughter broke down--she said you told her he had cancer."My heart sank.By the time I arrived at the ward,my consultant was already there,explaining that we still had to run lots of tests and that it was by no means confirmed that he had cancer.I stood silently at the end of the bed.My consultant was obviously angry with me and as we left Mr. McMahon,she turned to me."Why on earth did you do that?"she asked in disbelief.I looked at her and bit my lip."She asked me what I was worried about and I told her."I said,hanging my head."And give her more to worry about?"replied my consultant."You don't say the word'cancer'until it's confirmed.Even if you suspect it,think very carefully before you tell people." As it turned out, it wasn't cancer.But I did learn that when someone is stressed and worried about their loved one they're sometimes selective in what they hear and as a... The author's consultant was angry with him because   _   . A) he told the daughter what he suspected B) he delayed running the necessary tests C) he failed to confirm the patient's disease D) he forgot what the consultant had advised

"Can I see my baby?" asked the happy new mother. The bundle was placed in her arms and when she moved the fold of cloth to look upon his tiny face, she held her breath-the baby had been born without ears. Time, however, proved that the baby's hearing was perfect except his appearance. One day when he rushed home from school and threw himself into his mother's arms,. he cried  out bitterly, "A boy, a big boy ... called me-a f - freak. " She sighed, knowing that his life was to be endless of heartbreaks. He grew up, handsome for his misfortune. A favorite with his fellow students, he might have been class president but for that. He developed a gift for literature and music. The boy's father had a talk with the family doctor. Could nothing be done? "I believe we could transplant on a pair of outer ears, if they could be donated , " the doctor decided. So the search began for a person who would' make such a sacrifice for a young man. Two years went by. Then,  " You ' re going to the hospital, son. Mother and I have someone who will donate the ears you need. But it' s a secret." said the father. The operation was brilliantly successful. His talents blossomed into genius. School and college became a series of successes. Later he married and entered the diplomatic   service. "But I must know! " he urged his father.   "Who gave so much for me? I could never do enough for him. " "I do not believe you could," said the father,  "but the agreement was that you are not to know .... not yet. " The years kept the secret, but the day did come ... one of the darkest days that ever pass through a son. He stood with his father over his mother' s casket   . Slowly and tenderly, the father stretched forth a hand and raised the thick, reddish - brown hair to let out the secret. What moral lesson can we draw from this reading? A) Real love lies in what is done unknown rather than what is done known B) It is up to parents to help their children heart and soul. C) True beauty lies only in the heart not in appearance. D) It is a virtue for young generations to learn to be grateful.
