I've never been the kind of person to say, “it's the thought that counts” when it comes to gifts. That was until a couple of weeks ago, when my kids gave me a present that blew me away.

    For years now, I've been wanting to sell our home, the place where my husband and 1 raised our kids. But to me, this house is much more than just a building.

    In the front room, there's a wall that has hundreds of pencil lines, marking the progress of my children's growth.

    Every growth stage is marked in grey, with each child's name and the date they were measured. Of all the objects and all the memories, it's this one thing in a home that's the hardest to leave behind. Friends I know have returned home after work only to discover their wall of heights has been freshly painted over. A new paint job wouldn't normally be greeted by tears, but erasing that evidence of motherhood hurts more than it should. Our kids grow in so many ways, but the wall is physical evidence of their progress, right there for everyone to see.

    Over the years, I've talked about how much I would hate leaving that wall behind when I moved, even though the last marks were made 10 years ago when my kids stopped growing.

    So one day, while I was at work, my children decided to do something about it.

    They hired Jacquie Manning, a professional photographer whose work is about capturing (捕捉) the beautiful things in life, from clear lakes and skies to diamonds and ballgowns (舞会礼服).

    She came to our house while I was at work, and over several hours, took photos of the hundreds of drawings and lines, little grey fingerprints (手印), and old marks. Somehow, she managed to photograph all those years of memories perfectly. Afterwards, she put all the photos together into one image, transforming them into a beautiful history of my family.

    Three weeks later, my children's wonderful gift made its way to me—a life-size photo of the pencil lines and fingerprints that represents entire lifetimes of love and growth.

    Jaden Hayes first lost his dad when he was four and then last month his mom died unexpectedly in her sleep.

    “I tried and I tried to get her awake—I couldn't,” said Jaden.

    Jaden is understandably heartbroken. But there's another side to his sadness. When he first made public a few weeks ago he told his aunt, and now guardian, Barbara DiCola, that he was sick of seeing everyone was sad all the time. And he had a plan to fix it. He asked his aunt Barbara to buy a lot of little toys and bring him to downtown Savannah, so he could give them away.

    “I'm trying to make people smile,” said Jaden. He gave his toys to people who weren't smiling and then turned their day around. He has gone out on four different occasions now and he is always successful, though sometimes he doesn't get exactly the reaction he was hoping for.

    It's just so unexpected to some people that a six-year-old child would give away a toy— expecting nothing in return—except a smile. Of course he is paid beautifully in hugs and his aunt says the reactions have done wonders for Jaden, who will then feel joyful.

    “But I'm still sad that my mom died,” Jaden said.

    This is of course not only a fix, but the smiles he has made so far—nearly 500 at last count—Jaden has clearly found a purpose.

    “I'm counting on it to be 33, 000,” said Jaden.

    When asked if he thought he could make that goal, he answered, “I think I can.”

    Are you a procrastinator（拖拉者）? It's a common problem. And it can be harmful, as previous research has shown that people who procrastinate have higher levels of stress and lower well-being, reported the Association for Psychological Science in the US. But a new study has found a way to deal with this problem: Be more connected to your future self.

    Psychologists think that each person believes that they are really two people: “Present Me” and “Future Me”. “People act as if they prefer their current selves' needs and desires to those of their future selves,” wrote psychologists Neil Lewis and Daphna Oyserman.

    Oyserman and Lewis decided to try to find a way to make “Present Me” imagine exactly how “Future Me” would feel the night before a big paper was due, though “Present Me” hadn't started yet. They made “Present Me” think about a far-off event as a number of days away, not months or years.

    Thinking about events in this way meant that something like a friend's wedding seemed 16.3 days sooner when considered in days rather than months and 11.4 months sooner when considered in months rather than years.

    The researchers also tried to find out whether people would take action sooner if they were told a certain event was happening in X days rather than years.  For example, participants imagined they had a newborn child, and that the child would need to go to college in either 18 years or 6,570 days. The researchers found those in the “days” condition planned to start saving four times sooner than those in the “years” condition.

    So if you think of your life in days instead of years, you may get things done quicker.

    Parents who help their children with homework may actually be bringing down their school grades. Other forms of parental involvement, including volunteering at school and observing a child's class, also fail to help, according to the most recent study on the topic.

    The findings challenge a key principle of modern parenting(养育子女) where schools expect them to act as partners in their children's education. Previous generations concentrated on getting children to school on time, fed, dressed and ready to learn.

    Keith Robinson, the author of the study, said, "I really don't know if the public is ready for this but there are some ways parents can be involved in their kids' education that leads to declines in their academic performance. One of the things that were consistently negative was parents' help with homework." Robinson suggested that may be because parents themselves struggle to understand the tasks. "They may either not remember the material their kids are studying now, or in some cases never learn it themselves, but they're still offering advice."

    Robinson assessed parental involvement performance and found one of the most damaging things a parent could do was to punish their children for poor marks. In general, about 20% of parental involvement was positive, about 45% negative and the rest statistically insignificant.

    Common sense suggests it was a good thing for parents to get involved because "children with good academic success do have involved parents", admitted Robinson. But he argued that this did not prove parental involvement was the root cause of that success. "A big surprise was that Asian American parents whose kids are doing so well in school hardly involved. They took a more reasonable approach, conveying to their children how success at school could improve their lives."

    In 1988, after being diagnosed with kidney cancer, Fenn, a high-end gallery owner, came up with a crazy plan: He would bury some of his favorite artifacts somewhere in the Rocky Mountains and then die next to them. "My desire was to hide the treasure and let my body stay there and go back to the soil," he explains.

    The contents are worth somewhere between $I million and $5 million. Then he took his treasure chest out into the Rockies and hid it.He wanted it to be found. But he wasn't going to just give it away.

    In 2010, Fenn self-published a book, The Thrill of the Chase, which includes a 24-line poem that Fenn claims contains nine clues that "will lead to my treasure."

    At first, nobody really noticed. But word spread, and the chase was on.(The book is now out of print, and copies show up on Amazon for as much as $3,200.) Fenn estimates that 350,000 people from across the globe have searched or are currently searching for his treasure. Yet nobody has found it.

    The problem with Fenn's poem is that the "clues" can be interpreted a million different ways. The "home of Brown," for instance, could be Browns Canyon National Monument in Colorado, or Brown Hill in New Mexico. Or a cabin or a bear.(Don't laugh; several people have already looked.)

    "It's all in the poem," some have recently started sharing more details," and the treasure isn't in a mine, I mean, they have snakes in' em. It's between 5,000 feet and 10,200 feet above sea level. It's not in Canada or Idaho or Utah or a grave-yard."

    Why are Fenn's treasure hunters so into what seems like a ridiculous thing to do with their time? Many are quick to say that their lives have been enriched by their experiences. "It's changed us," Neitzel says. "made us more confident, and even saved our marriages. Nothing scares us anymore." They thank Fenn for giving them a reason to take a risk, for giving their lives meaning. Many claim that even if they found Fenn's chest, they wouldn't necessarily spend the money—and might even rehide the chest. Another hunter had this tantalizing insight: "I hope that I never find the treasure. The journey will be treasure enough."

    And so the hunt continues.

    A new study suggests that patients with breast cancer who take additional vitamins during chemotherapy(化疗) treatment may face increased risks.

    Researchers said the use of dietary supplements(补充剂) that increase levels of antioxidants, iron, vitamin B12 and omega-3 fatty acids appeared to lower the effectiveness of chemotherapy. Researchers reported their findings in the Journal of Clinical Oncology.

    Christine Ambrosone is the head of cancer prevention and control at the Roswell Park Comprehensive Cancer Center in Buffalo, New York. She said, "From this study and others in the literature, it seems that it may not be wise to take supplements during chemotherapy."

    "It's thought that antioxidants might interfere with the ability of chemotherapy to kill cancer cells," Ambrosone said.

    Some doctors have been advising patients for a number of years not to take antioxidants during chemotherapy. "But there was no strong empirical data for that recommendation," Ambrosone said.

    So, Ambrosone and other researchers decided to study whether supplement use might affect chemotherapy's effectiveness. They looked for evidence in an earlier study on diet, exercise, lifestyle and cancer results.

    In the earlier research, people who took part were asked about their use of supplements at the beginning of and during treatment, and about their lifestyle, diet and exercise. The researchers studied 1,134 patients who filled out the surveys and followed them for a median of six years.

    The researchers searched for possibilities that might increase the risk of the disease reappearing or of death. They found that patients who took any supplements at the beginning of and during chemotherapy were 41 percent more likely to have their breast cancer return than those who did not. In addition, the supplement takers were 40 percent more likely to die later on compared to patients using no supplements. The supplements included vitamin A, C and E. Those taking vitamin B12 and iron supplements were at greater risk of cancer returning, the researchers said.
