Taking an afternoon nap could keep your brain sharp, a new study has found. Adults ages 60 and older who took afternoon naps showed signs of better mental mind compared to those who didn't nap, according to a study published in General Psychiatry earlier this week.

Researchers analyzed napping habits in 2, 214 Chinese people aged 60 and older and measured their cognitive abilities using several cognitive tests. Participants took the Mini-Mental State Examination and the Beijing version of the Montreal Cognitive Assessment, both of which test for memory, language and other cognitive abilities. In every category listed in the study, nappers scored statistically higher on average compared to those non-napping people. Researchers did not gather data from people under 60, so a correlation cannot be drawn between napping and younger generations.

Sleeping behaviors can be affected by a variety of factors, said Dr. David Neubauer, associate professor at Johns Hopkins University. Daily routines, medication use and sleep disorders can all play a role in how frequently someone takes a nap, he said.

Neubauer recommended taking a shorter "power nap" of up to 20 minutes to decrease the chances of transitioning into slow-wave sleep, which makes people feel dizzy when they wake up. Napping can be a healthy part of an older adult's day, Neubauer acknowledged, but make sure sleepiness isn't due to a treatable nighttime sleep disorder. "Older individuals who want to do all they can to preserve their cognitive functioning should put nighttime sleep in the first place."

    Here is an astonishing and signficant fact:Mental work alone can't make us tired. It sounds absurd. But a few years ago, scientists tried to find out how long the human could labor without reaching a stage of fatigue(疲劳). To the amazement of these scientists, they discovered thett blood passing through the brain, when it is active, shows no fatigue at all! If we took a drop of blood from a day labourer, we could find it full of fatigue toxins(毒素) and fatigue products. But if we took blood from the brain of Albert Einstein, it would show no fatigue toxing at the end of the day.

    So far as the brain is concerned, it can work as well and swiftly at the end of eight or even twelve hours f efforts as at the beginning. The brain is totally tireless. So what makes us tired.

    Some scientists declare that most of our fatigue come from our mental and emotional(情感的) attitudes. One of England's most outstanding scientists. J. A. Hadfield,says,“The greater part of the fatigue from which we suffer is of mental origin. In fact,fatigue of purely physical origin is rare.” Dr. Brill, a famous American scientist, goes even further. He declares,“One hundred percent of the fatigue of a sitting worker in good health is due to emotional problems.”

What kinds of emotions make sitting workers tired?Joy?Satifaction?No!A feeling of being bored,anger,anxiety,tenseness,worry,a feeling of nt being appreciated—those are emotions that tire sitting workers.Hard work by itself seldom causes fatigue.We get tired because our emotions produce nervousness in the body.

    Japanese technology giant Toshiba has built a huge "clean" factory farm where it is growing various types of lettuce (莴苣) leaves without sunlight or soil for sale in its new healthcare business.

    Located in a disused 21,000­square­foot electronics factory in Yokosuka, Toshiba announces to have created a perfect "bacteria­free" environment where it will grow three million bags of lettuce a year.

    Completely cut off from conditions outside the temperature controlled tank, lettuce inspectors wear full body suits while making notes on the quality and growth of the leaves on their iPads in order to prevent the air around the plants becoming contaminated.

    Each plant is given man­made lighting to trick it into believing it is exposed to sunlight, while vitamin and nutrients are put directly into its roots, meaning the lettuce does not need soil.

    Toshiba's new high­tech farm may produce the world's highest quality lettuce. The final product will be free of any form of bacteria or insect life before being placed into sealed (密封的) bags, which should ensure the product has a longer shelf life than other lettuces.

    The gardening technique aims to have a bacteria amount of no more than 1/1000th­much lower than that found in normal gardening soil.

    Toshiba aims to harvest three million bags of leaf lettuce, baby leaf greens, cabbages and other kinds of vegetables every year­with each bag likely to cost people £1.

    The most important thing in organic vegetables, the lettuce requires no pesticides (杀虫剂) but is expected to have a similar shelf to plants that have been heavily treated with chemicals.

    The lettuce factory is no marketing trick by Toshiba, however. Instead it represents the company's latest attempt to expand its technology­led business.

    There are already plans for the technology giant to build similar factories around the world over the coming years and it will also be selling the high tech equipment that allows factories to produce similar products of exceptionally high quality.

    Nottingham Goose (鹅) Fair started on the first Thursday in October and lasted 3 days. However, nowadays you won't find any geese there.

    The fair opened at 12: 00 on the Thursday by the Lord Mayor of Nottingham, but it has an interesting and shocking history.

    For starters, it wasn't always the largest fair in the area. And the main fair for the people of Nottingham in terms of trade and economy was the Lenton Fair held at Lenton Priory.

    In the Middle Ages the Lenton Fair overshadowed (使显得逊色) the Goose Fair in size and importance. Harrisons Calendar of Fairs for 1587 mentions the Lenton Fair but not the Goose Fair. However the Goose Fair competed with its local competitors and every year over 20, 000 geese from the Fens in Lincolnshire arrived to be sold to provide the traditional Michaelmas dish.

    It wasn't just for geese either. All kinds of things were sold at the Goose Fair: sheep, horses and cattle were also sold.

    The fair has been under threat of closure many times over the years. In 1764, they actually had cheese riots (暴乱) due to an increase of a third on the price of cheese compared with the previous year, which resulted in an attack on the stallholders (摊主) at the fair.

    By 1880 the fair was reduced to a three-day event, which started on the first Thursday of October. In 1928, the fair was moved from the market square to its present site in the forest which is far away from the city centre. Despite attempts throughout its history to prevent the fair, the income from rents paid by the stallholders is financially beneficial to the local government. So regardless of the cheese riots and the various attempts to prohibit it, Nottingham Goose Fair has survived to celebrate over eight centuries of fun.

    Does the amount of cash in a lost wallet influence how likely a person is to return it? Classical economic theories suggest that the greater the appeal, the less likely we are to be honest—but a new study turns the idea on its head, finding altruism(利他主义), and a powerful hate for viewing oneself as a "thief" outweigh the financial attraction.

    A team of researchers conducted a huge experiment concerning 355 cities in 40 countries. More than 17,000 identical wallets were dropped off at public places, each containing a grocery list, a key, and three business cards in the local language using made-up names and an email address. Some had no money while others contained the equivalent (等值) of $13.45.

    According to the research, people on average returned 40% of wallets with no money in them but 51%with money. It also shows extreme differences between countries. But although rates of people's honesty varied greatly from country to country, one thing remained remarkably constant: wallets with money, as opposed to no money, raised reporting rates.

    In the US, the UK and Poland, they repeated the experiment with even more money: $94.15, which increased reporting rates by an average of 11% compared to the smaller amount. They also found that having a key expanded reporting rates by 9.2%.

    The findings, which run counter to a fundamental principle of classical economics, suggest honesty, altruism and self-image can sometimes be more influential than economic self-interest.

    A purely economic approach to behavior suggests people would keep the wallets with the larger amounts of money due to the increased financial reward, but economics often doesn't account for a person's sense of honesty or self-image, according to behavioral scientists. Altruism also influenced the findings, the researchers say. Since the key is valuable to the owner but not the finder, this pointed toward an altruism concern in addition to the cost of negatively updating one's self image.
