A warm drink of milk before bed has long been the best choice for those wanting a good night's sleep. But now a study has found it really does help people nod off—if it is milked from a cow at night.

       Researchers have discovered that “night milk” contains more melatonin(褪黑激素), which has been proven to help people feel sleepy and reduce anxiety.

       The study,by researchers from Seoul, South Korea, involved mice being fed with dried milk powder made from cows milked both during the day and at night.

       Those givennight milk, which contained 10 times the amount of melatonin, were less active and less anxious than those fed with the milk collected during daytime, according to the study published in The Journal of Medicinal Food.

       Night milk quickened the start of sleep and caused the mice to sleep longer.

       While the effect of cows milk harvested at different time has not been tested on humans up to now, taking melatonin drugs has been suggested to those who are struggling to fall asleep at night.

Previous studies have also indicated that milk can be excellent for helping sleep because of the calcium content, which helps people to relax.

       Milk is also sugar-free and additive-free with nutritionists recommending skimmed milk as the best choice before bed as it is the least fattening. The more fat you take in before bedtime, the greater burden you will put on your body at night.

    What makes a person a giver or a taker? The idea of “give versus take” takes shape in all relationships of our lives. We're either giving advice, making time for people, or we're on the receiving end. We alternate between the two based on different situations we face on a daily basis, it not an hourly one.

    According to Adam Grant, a professor at Pennsylvania University, most people are matchers. They make careful observations on takers and make it a point for them to pay something back. They hate to see people who act so generously towards others without receiving any reward. Actually, most matchers will try to promote and support givers so that they can get the good they deserve.

    Another professor named Hannah Rile Bowles, from Harvard University, led a study on the idea. She asked 200 senior managers to sit down in pairs where one person would act as the boss and the other as an employee to negotiate salary promotions. Male employees asked for an average salary of $146 k while the females asked for only $141 k. But why did they not bargain as hard as the men? Simply because they were more likely to be givers.

    As a woman, I do enjoy the act of giving up my time, my knowledge and my care and attention to others. I don't expect anything in return, but I do tend to pull myself away when I feel like I'm being taken for granted. I also tend to get upset when I see a loved one's continuous actions of kindness go unnoticed. So it's safe to say I'm 50% giver,35% matcher and 15% taker.

    I do know someone, however, who is 99% giver. They're devoting their time, sharing valuable insights and going out of their way for everyone who crosses their path. Although they've changed the lives of many people, they rarely see any of it returned. But the universe is slowly repaying them; they're now extremely successful, well known for what they do.

    I found the last outdoor table at my favourite cafe. Reading as I ate my breakfast slowly, I was enjoying the feeling of the cool wind and the warm sun when a table next to me opened up. A woman, who had been standing nearby, clearly waiting for a seat, stepped towards the table. But from the other direction, straight from the parking lot, came a man who got to the table first.

    The woman, with a smile on her face, explained that she'd been keeping her eye on that table for several minutes and had been on her way over. The man, also smiling but determined, told her she was out of luck.

    She stood off the side, clearly disappointed, and greeted her friend with the disappointing news. I sat at my table, taking in the scene, and suddenly I realized that I had an opportunity to be kind.

    I stood up and asked her to come to my table. Quietly, I told her I had seen what had happened, and I was happy to give her my table. I was only going to be there a few more minutes anyway, so I was happy for her and her friend to have the seat.

    "But where will you sit?" she asked. I was almost done eating, I said, and I would find a seat at the counter (柜台) inside. She thanked me and beamed with delight as she invited her friend to sit down.

    Thinking about it as I finished up, I realized that whether or not the woman had acceptable demand for the table was unimportant. The feeling of the situation -- the look of hurt on her face -- had struck me, and I had the ability to do something about it.I just hope that woman's morning at the cafe was great. I know mine was.

    “Don't tell anyone”. We hear these words when someone tells a secret to us. But it can be hard to keep a secret. We5re often tempted to “spill the beans"，even if we regret it later.

    According to Asim Shah, professor in the Menninger Department of Psychiatry and Behavioral Sciences at Baylor College of Medicine, US, keeping a secret may well "become a burden”. This is because people often have an “obsessive and anxious urge to share it with someone”.

    An earlier study, led by Anita E. Kelly, a scientist at the University of Notre Dame, US, suggested that keeping a secret could cause stress. People entrusted (受委托的)with secrets can suffer from depression, anxiety, and body aches, reported the Daily Mail.

    But with secrets so often getting out, why do people share them at all? Shah explained that people often feel that it will help them keep a person as a friend. Another reason people share secrets is guilt over keeping it from someone close to them. A sense of distrust can develop when people who are close do not share it with each other. "Keeping or sharing secrets often puts people in a position of either gaining or losing the trust of someone,” according to Shah.

    He added that talkative people could let secrets slip out (泄露). But this doesn't mean that it is a good idea only to share secrets with quiet people. A quiet person may be someone who keeps everything inside. To tell such a person a secret may cause them stress, and make them talk about the secret.

    Shah said that to judge whether to tell someone a secret, you'd better put yourself in their position. Think about how you would feel to be told that you mustn't give the information away. Shah also recommended that if you accidentally give up someone's secret you should come clean about it. Let the person know that their secret isn't so secret anymore.

    Dr. Amanda Harris was ready for sleep since it was already 11 pm. The phone rang. On the other end of the line was a woman about to break a promise. The woman was her mother's neighbor. Flora Harris had made the neighbor swear she wouldn't tell her daughter she'd had a heart attack and was in hospital. The neighbor wisely decided to disobey orders.

    Amanda desperately wanted to get to the hospital immediately, but she couldn't. She lives in Washington D. C. and her mother lives in California. For the past year and a half, Amanda has gone to Los Angeles every other month to take care of her mother. Flora Harris takes care of her husband, James, who's 91 and has Alzheimer's disease. They live in their own home, and a caregiver comes to help them a few hours a day.

    Amanda is one of many Americans facing the heartache of how to take care of aging parents from afar. She's often worried and guilty, not to mention busy with a demanding job, two teenage daughters and the frequent trips to California.

    In some ways, Amanda is lucky. She has the resources to make the trips to Los Angeles. Plus, she is a doctor who treats the elderly. She's treated countless patients whose children live far away.

    “But it's still tough,” she says. “I can foresee what the next few years are going to look like, and it's not a pretty picture. There will come a time when my father won't recognize me and I worry he's going to be violent and hurt my mother.”

    So what do you do when you live a continent away from your aging, sick parents? You can hire someone to help, but you can't count on it completely.

    I grew up on a farm outside Port Clinton, Ohio. I was the youngest son, with four brothers and four sisters, plus a girl my relatives took in when she was in sixth grade and was raised along with us.

    By the late 60s, most of us were married and had families of our own. One day, while we were visiting my parents in late summer or early fall, Dad mentioned he'd always wanted a Crimson King maple tree for the yard. Mom agreed that they were pretty.

    Like many parents, mine were hard to shop for, so I figured this was a great opportunity to get them something they'd appreciate. I checked the price at work and decided it was a bit more than I could afford but all of my brothers and sisters agreed to help.

    In northern Ohio, people don't plant maple trees at Christmas, so we decided to surprise Mom and Dad with a special Christmas in October before the ground froze. We asked my aunt if she'd help us with the trick, and she called my parents in advance to say she was coming for a Sunday visit. Then my sisters and sisters-in-law went into action, planning a big holiday turkey dinner.

    On the chosen Sunday, we all met at my house and loaded the trees in a pickup truck. I dressed up as Santa Claus, though at the time I weighed about 140, so all the padding(填料) in the world couldn't make me look like St. Nick. Then off we went, nine or ten cars loaded with people and food, plus the pickup truck.

    When the truck arrived at my parents' house, Dad came out of the back door, convinced something was wrong. He and Mom were amazed when we told them why we were there.

    When Christmas rolled around, of course, we couldn't go to our parents' house empty-handed, so Mom and Dad got double presents that year. Almost half a century later, I still drive by the old farm and smile when I see those big, handsome trees.
