The most widespread fallacy (谬论)of all is that colds ire caused by cold. They are actually caused by viruses passing on from person to person. You catch a cold by coining into contact, directly or indirectly, with someone who already has one. If cold causes colds, it would be reasonable to expect the Eskimos to suffer from them forever. But they do not. And in the isolated Arctic Regions explorers have reported being free from colds until coming into contact again with infected people from the outside world by way of packages and mail dropped from airplanes.

    During the First World War soldiers who spent long periods in the trenches(战壕), cold and wet, showed no increased tendency to catch colds.

    In the Second World War prisoners at the Auschwitz concentration camp，naked and starving, were astonished to find that they seldom had colds. At the Common Cold Research Unit in England, volunteers took part in experiments in which they gave themselves to the discomforts of being cold and wet for long stretches of time. After taking hot baths, they put on bathing suits, allowed themselves to be with cold water, and then stood about dripping wet in drafty rooms. Some wore wet socks all day while others exercised in the rain until close to exhaustion. Not one of the volunteers came down with a cold unless a cold virus was actually dropped in his nose.

    If then, cold and wet have nothing to do with catching colds, why are they more frequent in the winter. Despite the most pains-taking research, no one has yet found the answer. One explanation offered by scientists is that people tend to stay together indoors more in cold weather than at other times, and this makes it easier for cold viruses to be passed on.

    Even though it's not the most popular time of year to get married, I allow my thoughts to wander and consider the most unusual marriage habits across the world.

    In some parts of India it is believed that ghosts can stay with certain people of the living world. In general, girls who are born with a baby tooth and girls who are very ugly or have some facial damage are believed to be owned by ghosts. The only way to free from the ghosts is for the girl to marry an animal, typically a goat or a dog. She is free to marry a man later on, when the ghosts are proven to be freed from her. I wonder who makes this decision and how they come to their conclusion.

    In Korea, it is a custom for grooms to request that their successfully married friends carve them wooden ducks as a symbol of great marriage. Hand-carving a wooden duck can't be easy. This leads me to wonder why it's a duck and not another animal.

    Imagine being as young as 5 and already your parents are sending you to a fat farm where you are forced to eat too much food until you vomit (呕吐). Then, the old woman watching you eat forces you to eat that vomit. This is not a TV show. This is really happening in some parts of Africa. Men there want women fat; the fatter the better. It doesn't matter if it ruins their health or make them live shorter lives. All that matters is that the woman is as large as possible in order to sell her for a high price when she reaches the age for marrying.

    The world's first luxury space hotel, Aurora Station, was announced Thursday at the Space 2.0 Summit in San Jose, California. Developed by US-based space technology start-up Orion Span, the space station will host six people at a time, including two crew members, for 12-day trips of space travel. It plans to welcome its first guests in 2022.

    "Our goal is to make space accessible to all," Frank Bunger, CEO and founder of Orion Span, said in a statement." Upon launch, Aurora Station goes into service immediately, bringing travelers into space quickly and at a lower price point than ever seen before."

    While a$10 million trip is outside the budget of most people's two-week vacations, Orion Span claims to offer an authentic astronaut experience. "It has taken what was historically a 24-month training to prepare travelers to visit a space station and streamlined(精简)it to three months, at a fraction(小部分)of the cost," says Bunger. During their 12-day adventure, the super-rich travelers will fly at a height of 200 miles above the Earth's surface in Low Earth Orbit, where they will witness incredible views of the blue planet. The hotel will orbit Earth every 90 minutes, which means guests will see around 16 sunrises and sunsets every 24 hours.

    Activities on board include taking part in research experiments such as growing food while in orbit, which guests can take home for a super-smug souvenir, and soaring over their hometown. Guests can have-live-video chats with their less-fortunate loved ones back home via high-speed wireless Internet access and, upon(return to Earth will be greeted with a specially arranged hero's welcome. While enjoying the thrills of zero gravity, the travelers will be able to float freely through the hotel, taking in views of the northern and southern aurora from the station's windows.   Deposits are already being accepted for future stays on the space hotel.

New App Helps People Remember Faces

    Large gatherings such as weddings and conferences can be socially overwhelming. Pressure to learn people's names only adds to the stress. A new facial-recognition app could come to the rescue, but privacy experts recommend proceeding with caution.

    The app, called SocialRecall, connects names with faces via smartphone cameras and facial recognition, potentially avoiding the need for formal introductions. "It breaks down these social barriers we all have when meeting somebody," says Barry Sandrew, who created the app and tested it at an event attended by about 1,000 people.

    After receiving an invitation to download SocialRecall from an event organizer, the user is asked to take two selfies and sign in via social media. At the event, the app is active within a previously defined geographical area. When a user points his or her phone camera at an attendee's face, the app identifies the individual, displays the person's name, and links to his or her social media profile. To protect privacy, it recognizes only those who have agreed to participate. And the app's creators say it automatically deletes users' data after an event.

    Ann Cavoukian, a privacy expert who runs the Privacy by Design Center of Excellence praises the app's creators for these protective measures. She cautions, however, that when people choose to share their personal information with the app, they should know that "there may be unintended consequences down the road with that information being used in another context that might come back to bite you."

    The start-up has also developed a version of the app for individuals who suffer from prosopagnosia, or "face blindness," a condition that prevents people from recognizing individuals they have met. To use this app, a person first acquires an image of someone's face, from either the smartphone's camera or a photograph, and then tags it with a name. When the camera spots that same face in real life, the previously entered information is displayed. The collected data are stored only on a user's phone, according to the team behind the app.

Smartphones can be a force for good. Your phone is always with you, making it the perfect device to push you into a more beneficial way of living. Here are some of the best apps that can help.

Habitica

Habitica turns the goal of forming good habits into a game, with its own characters and scoring. It's a lot of fun, and the app also lets you build habits with friends and family. In addition to regular repeating habits, you can add a more general to-do list, and the rewards you get can be customized too—you could treat yourself to a meal out or an extra hour of games.

Smoke free

If you're determined to give up smoking, Smoke Free is one of the most comprehensive apps for giving you that extra push you need to make a permanent change. The app offers a host of useful features to people wanting to go smoke-free: the ability to see your progress over time, charts showing how your health is improving, day-by-day encouragement, and some advice on techniques for giving up smoking.

MyFitnessPal

You can find tons of health and fitness apps for your phone, but My FitnessPal stands out not just because it is easy to use, but because it makes practical suggestions for you. It can take in a host of data, from the calories you're taking in to the number of swims you're doing per week, and offer reports on calorie consumption and macronutrient (大量营养素) breakdown.
