A man walked into a small Irish pub and ordered three beers. Bartender was surprised, but he served that man three beers. One hour later the man ordered three beers again. The very next day that man ordered three beers again and drank quietly at a table. This repeated several times and shortly after the people of the town were whispering about the man, who was ordering three beers at once.

    A couple of weeks later, the bartender decided to clear this out and inquired: “I do not want to pry, but could you explain, why do you order three beers all the time?” The man replied: “It seems strange, isn't it? You see, my two brothers live abroad at the moment, one – in France and another – in Italy. We have made an agreement, that every time we go to pub each of us will order extra two beers and it will help keeping up the family bond”.

    Soon all the town have heard about the man's answer and liked it a lot. The man became a local celebrity. Residents of the town were telling this story to newcomers or tourists and even invited them to that pub to look at Three Beer Man.

    However, one day the man came to pub and ordered only two beers, not three as usual. The bartender served him with bad feeling. All that evening the man ordered and drank only two beers. The very next day all the town was talking about this news, some people pray for the soul of one of the brothers, others quietly grieve.

    When the man came to pub the next time and ordered two beers again, the bartender asked him: “I would like to offer condolences to you, due to the death of your dear brother”. The man considered this for a moment and then replied: “Oh, you are probably surprised that I order only two beers now? Well, my two brothers are alive and well. It's just because of my decision. I promised myself to give up drinking.”

How to improve your happiness

    Recent research has shown that people who value their time over the pursuit of wealth are happier. So how can you best make, save and use your time — and ensure you keep a smile on your face?

    On April 2, we said goodbye to Tiangong I, China's first space lab. According to the China Manned Space Agency（中国载人航天）, Tiangong I re-entered the Earth's atmosphere （大气层）and fell into the South Pacific Ocean.

    There are many spacecraft that are still in orbit above the Earth. They are flying at heights ranging from 300 to 1,000 kilometers. After finishing their trips, they will all re-enter the Earth's atmosphere like Tiangong I.

    There are two types of re-entries：controlled（受控的）re-entry and uncontrolled re-entry.

    Some satellites（卫星）and manned spacecraft come back to the Earth in a controlled re-entry. Scientists calculate（计算）the path of the falling spacecraft and its speed. They can guide the spacecraft to fall in a chosen area. In 2017,Tianzhou I, China's first cargo（货运）spacecraft, was directed to fall in the South Pacific Ocean.

    Some spacecraft may have problems while in space, or are simply no longer usable after a certain amount of time.  These craft come back in an uncontrolled re-entry.  It is hard to tell when and where these spacecraft will fall until the last few hours. The US space station Skylab came back partially uncontrolled in 1979. Parts of the station fell in western Australia, but no one was injured.

    During re-entry, most of the spacecraft will burn up while passing through the Earth's atmosphere. Only a small amount of the debris（碎片）will reach the ground.

    The debris typically ends up falling into the ocean, China Daily reported. Tiangong I weighs about 8.5tons. The amount of debris that falls to the Earth might be about 1 to 1.5 tons, the Beijing News reported.  That is about the same weight as a car.

    Austin Perine, a four-year-old boy, discovered that sympathy for the less fortunate can produce superhuman results.

    Once Austin's father, TJAustin, took Austin to the Firehouse Ministries, a local shelter that provides housing, food, and other services for homeless men. As they drove by the redbrick building, they saw a group of 25 homeless men standing on the street corner. "Dad, they look sad," Austin said. "Can we take them some food and make them smile?"

    That day, Austin used his allowance to buy each man a Burger King sandwich and handed the food out himself.

    Seeing what their presence meant to the men at the ministry, Austin and TJ returned the next week. After he returned every week for five weeks, word of Austin's acts of kindness spread through social media and national news outlets. Burger King jumped aboard, agreeing to donate $1,000 a month for an entire year toward the cause. Soon, churches and shelters across the country began inviting Austin to come and distribute food in other poor areas. Whereas before Austin and TJ could feed 25 to 50 people at a time, now, thanks to corporate and community support, they can feed 800 to 2,000 people at once.

    But Austin isn't just filling bellies. He's improving the lives of those he meets. On that first trip to Firehouse Ministries, TJ and Austin talked to a man named Raymont. The respect Austin gave 41-year-old Raymont touched the man. TJ helped Raymont collect all the credentials(资格) he needed to get a driver's license. The license helped Raymont get a job. And with money in the bank, he was able to rent his own apartment. All that was made possible because a little boy took the time to care.

    Many of us have had this experience: we lie down in a bed other than our own, perhaps at a friend's house or in a hotel room, and find it difficult or impossible to fall asleep. Is it because the bed is uncomfortable? Maybe, but perhaps there can be other reasons.

    According to a new study published in Current Biology, a significant reason is what the scientists call "first night effect". They believe that one side of the brain acts as a "night watch" to warn us about potential dangers. It forces us to stay awake on the first night in a new environment.

    For the study, 35 young volunteers were asked to sleep in a sleep lab for several days. Meanwhile, researchers watched their brain activities.

According to the researchers, on their first night, the left brains were more active than the right brains and people had a hard time sleeping. However, left-brain activity decreased as days went by, falling even to the point of complete calm. In this process, the participants got an increasingly better sleep experience.

    The findings suggest that the different rhythms of the sides of the brain affect our sleep. When the two sides work differently, the balance between them is broken. Thus, the brain can't relax and is sensitive to anything strange in the surroundings, just as it is in daytime.

    "At some level, the brain is continuing to analyze things, even though you are not aware of the analysis," US professor Jerome Siegel told Smithsonian Magazine. "If something unusual happens – if a door opens or you hear a key in a lock – you can be alert, even though the intensity of the stimulus is quite low."

    More surprisingly, this phenomenon is similar to the way some animals sleep. Whales, dolphins, and many birds can sleep with half of their brain while the other half stays awake, with its corresponding eye staying open.

    The researchers think that it is the result of evolution, and works to protect us in potentially dangerous environments.

    If you have ever had what you think is "first night effect", researchers suggest that you bring your own pillow or sleep in a room similar to your bedroom next time you sleep away from home.

I came across an image recently of a distance runner with a message that told readers to persevere (坚持) at all costs. It reminded me of a conversation I had. My colleague's teaching assistant was asking for my advice. He wanted to know when to quit something. He described how he'd been playing an online game with people for some time. It hadn't been very fun lately, but there was always that small chance of a reward (upgraded equipment, etc). 

I inquired further about his relationship with the players and his gains from the game. I then discussed the sunk cost dilemma, a concept I studied in advanced school due to its personal impact. In high school, I applied to five universities, planning to choose the cheapest one. SUU offered the best scholarship, and after paying a $100 commitment fee, I heard back from another school with an even better scholarship. Despite the new offer, I stayed committed to SUU, believing that switching schools, even if it meant acknowledging the "wasted" $ 100, would have been the wiser financial choice. 

A rational (理性的) decision maker is not ruled by past investments, but weighs future outcomes. I didn't focus on future outcomes when weighing colleges. I focused on the money I sunk into SUU. Rather than evaluating future career options, I focused on the fact that I'd already taken elementary education courses. 

I'm not the only one that's fallen prey to this. I wear clothes I dislike simply because I spent money on them (and that money won't come back). Unhealthy relationships last because of the invested time (leading to more unhappy years). However, time, effort, or money that you've invested doesn't mean you should continue. Society often stresses perseverance — never quit, never give up, don't waste. However, only you know your right path. Walking away can be the toughest choice. You might realize a path you're on is no longer the right one or never was.
