Chinese e-commerce websites fail to pay more attention to older consumers, says a news report.

    There's been a thought that younger consumers have been the driving force of online buying. That may not be the case. According to a statement from Alipay, the average expenditure (支出) of Alipayusers born before the 1960s was 31,000 yuan in 2012, much higher than 14,000 yuan of those born after the 1980s. It shows that online shopping has become akey part of people's daily consumption, for both young and old.

    Besides shopping, people pay bills such as water bill, electricity bill, and credit card repayment online. The middle-aged and senior consumers are also participating in that consumption revolution.

    Liu Chen, 56, said that his online expenditure in 2014 was over 50,000 yuan, about half of the total annual expenditure. He always pays his telephone bill online. Clothes, electrical appliances and kids' snacks are themain items he purchases online.

    Liu's shopping strategy is to find something good online first, then go to shops to check it out, and finally buy it online because it is cheaper. As quality concerns him, Liu only buys items that come with aguarantee.

    Stories such as those from Liu are representative of millions of middle-aged and older Chinese, which show the great potential of the aged inthe Chinese consumption market. Yet, the market seems not to be valued as it should be.

    Some Chinese e-commerce websites such as jd. com, dangdang. comand amazon. cn don't have a category for goods for the elderly on their mainpages. Alibaba's platform does have one, but the goods in it are not as abundant as other categories. Moreover, Taobao's category is not really designed for elders, but their children.

    Despite the seeming lack of commitment to older consumers, the Chinese market for the elderly is clearly huge, and e-commerce websites should takegreat efforts to develop it.

    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 given night 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.

    It's been said that honesty is the best policy．It sounds like the simplest thing in the world，but being truly honest with others and with yourself can be a real challenge．Most of us learned to be dishonest as children．Remember that dishonesty is rooted in fear，so you must look for and face those fears．By listing areas where you have a problem，and then working to deal with them，you can battle these habits．If you find yourself lying because you fear disapproval from someone，for example，perhaps you need to learn how to stop being a people pleaser and be yourself．Most importantly，admit your errors so that you can forgive yourself and use those experiences to reinforce your determination to do better．

    If you feel guilty for having been dishonest in the past，apologize to the person you lied to or find a creative way to make things right．If you've lied to a person who plays an important role in your life （a significant other，relative，or friend），the best （but most difficult） thing to do is to come clean．

    Think honestly．This may sound silly，but if you don't think honestly，you won't be honest．

    If you're pushed into a corner and don't know how to respond，you have the right to remain silent or say"Can we talk about this another time?"or"I really don't feel comfortable talking about this．"Don't say"I don't know．"

    Practice being honest on the simple things．Abraham Lincoln became famous for going to great lengths to return a few cents that did not belong to him，hence the nickname"Honest Abe"．By applying honesty to the little things，you will get in the habit of being honest in general．

    Social media is one of the fastest-growing industries in today's world. Your friends' lives may look more exciting than yours on Facebook, Twitter, and Instagram, but a new research shows it is because they are faking(伪造) it.

    A recent survey has found around two-thirds of people on social media post images to their personal information to make their lives seem more adventurous. And more than three quarters of those asked said they judged their peers based on what they saw on their Instagrm, Snapehat or Facebook pages.

    The British survey, by smart phone maker HTC, found that, in order to make our own pages and lives appear more exciting, six percent also said they had borrowed items to include in the images in order to pass them off as their own. More than half of those surveyed said they posted images of items and places purely to show off, causing jealousy among friends and family.

    Behavioral psychologist Hemmings said the trend was unsurprising due to the rise of social media. "We're living in a world instant communication." she said. "Fashion and style used to live and die in magazines; now people are in search of authentic, peer-to-peer recommendations as well, making social media an equal power house to magazines and newspaper."

    "With images being shared in an instant, we desire to know what our friends are wearing, or what super stars are buying, as soon as they have got them." Such is the influence of social media sites like Instagram, 76 percent of those asked also said seeing items on social influences them to buy them, with men more likely to take style advice and buy what they see.

    China's government has been trying all measures to reduce pollution in the past few years. Now people can enjoy a fresh environment everywhere. The following two graphs are adopted from the column of “City Information” on the webpage of Beijing Review.

Notes:

    API stands for Air Pollution Index(指数).

    Particulate matter (PM10) is a major component of air pollution that threatens both our health and our environment. It consists of very small liquid and solid particles floating in the air.

    Sulfur dioxide(SO₂) acts as an acid. Inhalation(吸入) results in labored breathing, coughing, or a sore throat and may cause permanent lung damage.

    Some educators told us that more years of school could help students get higher scores on intelligence tests. That was a finding of a study of teenage males in some countries. Now, another research shows that physical activity may help students do better in their classes.

    The research comes as educators in some countries are reducing time for activities like physical education. They are using the time instead for academic(学术的) subjects like math and reading. The studies appeared between 2008 and 2014. They included more than 55,000 children, aged 6 to 18.

    Amika Singh: "According to the results of our study, we can conclude that being physically active is beneficial for academic performance. There are, first, Physiological explanations, like more blood flow, and so more oxygen to the brain. Being physically active means there are more hormones(荷尔蒙) produced like endorphins(内啡肽). And endorphins make your stress level lower and your mood improved, which means you also perform better."

    Also, students taking part in organized sports learn rules and how to follow them. This could improve their classroom behavior and help them keep their mind on their work.

    The study leaves some questions unanswered, however Ms Stash says it is not possible to say whether the amount or kind of activity affected the level of academic improvement. This is because of differences among the studies.

    The researchers said they found only two high­quality studies. They needed more high­quality studies to confirm(证实) their findings. They also pointed out that "results for other parts of the world may be quite different".

    Still, the general finding was that physically active kids are more likely to do better in school. Ms Singh says schools should consider that finding before they cut physical education programs. Her paper on "Physical Activity and Performance at School" is published in the Archives of Pediatric and Adolescent Medicine.
