With fuel costs rising and airlines finding more fees to impose （强加，征税）on travelers every day, airfare isn't getting any cheaper. Since you can't drive to all your dream destinations, flying is the only way to go sometimes and, undeniably, the fastest. Luckily, there are plenty of ways to find the most affordable fares and also avoid paying as many extra charges as possible when you plan ahead.

    Get the best fare. Airlines put out their fare sales on Tuesday morning, making this day the best day to book a flight for less.

Fly during the least popular times. Tuesday, Wednesday and Saturday are the slowest days to fly, which means cheaper deals than the rest of the week. You can also find reduced rates on early morning flights, since many people don't like to get up before the sun to get to the airport. Earlier boarding times can also considerably cut down your chances of getting bumped on an overbooked flight or delayed because of other delayed flights or mechanical issues.

    Choose your seat later. Some airlines charge you to pick your seat when you book online, adding even more to the bottom line of your ticket cost. If you show up early on your travel day, you can still get suitable seats. Some of the best seats get held back until flight day, unless others are willing to pay extra for them ahead of time, so you still have the chance at one of those.

Fly on holidays. You already know that summer is the most expensive time to fly, and even though most other times are more affordable, the days surrounding holidays can be crazy. Save big if you're willing to travel on major holidays, such as Thanksgiving and Christmas.

Don't wait until the last-minute to book. Many travelers don't know that there's a sweet spot for booking and getting the best price on your tickets. Book too early or too late and you could end up paying more than you need to. The best time to book is between three months and six weeks from when you want to travel.

    Soaping up your hands may do more than just get rid of germs. It may wash away the inner confusion you feel right after being forced to make a choice between two appealing choices, according to a new study. The study builds on past research into a phenomenon known as “the Macbeth effect”.

    It turns out that Shakespeare was really onto something when he imagined lady Macbeth trying to clean her conscience（良心）by rubbing invisible bloodstains from her hands. A few years ago, scientists asked people to describe a past wrong act. If people were then given a chance to clean their hands, they later expressed less guilt than people who hadn't cleaned.

    This finding fascinated W. S. Lee, a researcher. “Anything from the past, any kind of negative emotional experiences, might be washed away,” says Lee.

He decided to test hand washing's effect on one kind of bad feeling: the tension we feel after being forced to choose between two attractive choices, because picking one choice makes us feel that we've lose the other. People usually try to calm this inner conflict by later exaggerating（夸大）the positive aspects of their choice.

    He had students rank 10 different music CDs. Then be offered students one CD as a gift. Some students then use liquid soap. Others only looked at the soap or sniffed（噢）it. “Actually, you do not need water and soap,” says Lee.

    Later, the students again had to rank all the music. People who didn't wash their hands had the normal response — they scored their take-home CD higher. Suggesting that they now saw it as even more attractive than before. But this wasn't true for the hand washers. They ranked the music about the same. “they feel no need at all to justify the choice,” say Lee.

    But the implications of it just aren't clear. Schwarz says it's too soon to know whether people should head for a sink after making a tough choice. He says washing may help decision-makers by cleaning away mental disorder, but perhaps if they don't go through the usual post-decision process of justifying their choice, they might feel more sorrow in the long run.

    Songs that make our hearts happy can make them stronger too, US researchers reported on Tuesday.

    They found that when people listened to their favorite music, their blood vessels (血管) dilated in much the same way as when they are laughing, or taking blood medications.

    “We have a pretty impressive effect,” said Dr Michael Miller, director of preventive cardiology (心脏病学) at the University of Maryland Medical Center in Baltimore.

    “Blood vessel diameter improved,” he said.“The vessel opened up pretty significantly. You can see the vessels opening up with other activities such as exercise.” A similar effect is seen with drugs such as statins.

    When blood vessels open up more, blood flows more smoothly and is less likely to form the clots (凝块) that cause heart attacks and strokes. “We are not saying to stop your statins or not to exercise but rather to add this to an overall program of heart health,” said Miller, who presented his findings to a meeting of the American Heart Association in New Orleans.

    Miller's team tested 10 healthy, non-smoking men and women, who were told to bring their favorite music.They spent half an hour listening to the recordings and half an hour listening to music they said made them feel anxious while the researchers did ultrasound tests designed to show blood vessel function.

    Compared to their normal baseline measurements, blood vessel diameter increased 26 percent on average when the volunteers heard their joyful music.Listening to music they disliked — in most cases in this group — blood vessels narrowed by six percent, Miller said.

    Miller said he came up with the idea after discovering that laughter caused blood to literally flow more smoothly. “I asked myself what other things make us feel really good, besides calories from dark chocolate of course.Music came to mind. It makes me feel really good,” he said.

    Most of the volunteers chose country music but Miller said the style is not so important rather than what pleases each individual.

    John George, 60, remembers that he lived a wonderful life in the Detroit neighborhood where he grew up. "We knew all our neighbors." George told Detroit's Metro Times. "On Christmas Eve, we'd all go to midnight Mass, and there'd be 300 people in our house at one o'clock to about five in the morning. The folks were just really good, hardworking people."

    By the'80s, however, the old neighborhood changed. Due in part to economic downturns and drug abuse, well -kept homes had been abandoned and kindly neighbors had fled to the suburbs(郊区). But not George. "Living in any city, it's like being in a relationship," he told Reader's Digest. "Some days are better than others. But it was my home. And when I saw it becoming worse, I had two choices: I could leave, or I could stay and fight. I chose the latter."

    When the abandoned home behind his turned into a worn-out place, the father of two grabbed some boards and nails and began boarding up the house. After two neighbors stopped to ask what he was doing, they decided to help, with great results.

    That's how it all got started. In the 30 years since that first home rescue, an army of approximately 182,000 volunteers, along with private donors, has helped George pull down around 300 abandoned homes, mainly in die poorer Northwest area of Detroit. They've also secured 400 - some homes by boarding them up. They've painted and repaired nearly 900 homes and built over 100 from scratch. According to Forbes, more than 1,000 Detroiters have been housed as a result of their work.

    And there's Halloween. In Detroit, October 30 was known as Devil's Night, a period when all hell break loose in the form of crime and vandalism (破坏公物). In response, George created a citizens' patrol(巡逻)that would take to the streets, keeping an eye on illegal behavior. He named it Angels' Night What began with 12 neighbors on patrol in 1990 has grown to more than 60,000 citywide.

    George's inspired ideas have not gone unnoticed by the city he loves. Others are buying into it. There's a trend of younger homeowners coming in.

    Alison Malmon was trapping up (完成) the end of her freshman year at the University of Pennsylvania, US when she got the news: Her older brother Brian, a student at Columbia University, was suffering from mental illness.

    Inspired by this, Malmon formed a group at her university to empower (使能够) students to talk openly about mental health. It soon blossomed into a national organization that today has more than 450 campus chapters. Leaders with the organization spend their time talking with college students about the pressure that today's young people face.

    "What you hear often is just a need to be perfect," said Malmon, "and a need to present oneself as perfect."

    And a new study in the UK proved that this need for perfectionism is simply part of today's society. In the study, two researchers studied more than 40,000 students from the US, Canada, and the UK. They found that what they called "socially prescribed(社会定向型的) perfectionism" increased by a third between 1989 and 2016.

    Lead researcher Thomas Curran said that while so many of today's young people try to present a perfect appearance online, social media isn't the only reason behind this trend. Instead, he said, it may be driven by competition in modern society, meaning young people can't avoid being sorted and ranked in both education and employment. That comes from new norms(准则) like greater numbers of college students, standardized testing and parenting that increasingly emphasizes success in education.

    For example, in 1976, half of high school seniors expected to get a college degree of some kind. By 2008, more than 80 percent expected the same. The researchers also said changes in parenting styles over the last two decades might have had an impact. As parents feel increased pressure to raise successful children, they in turn pass their "achievement anxieties" onto their kids through "excessive(过多的) involvement in their child's routines, activities or emotions"

    Those in the mental health community like Malmon say they're concerned about the impact the culture of perfectionism has on mental health on campuses. "Mental health has truly become this generation's social justice issue," she said. "It's our job to equip them with the tools and to let people know that it's not their fault."
