2 . In the race to catch up with the changing time, we are forgetting how to live without the support of our phones, laptops, and tablets.    1    

The first thing you need to do to unplug is to turn off your phone notifications. As soon as we hear a notification drop on our phones — whether it is something of importance or not — we are attracted to check it. When you’re not working and are not required to call, text, or return an email, turn off your phone (or put it on silent mode).     2    

I know it’s hard to stay away from your phone when it keeps buzzing with incoming texts, calls, and emails.     3     Create a rule: no phone on the dinner table, no replying to work emails after work hours, etc.

One of the best ways that I believe can help you disconnect is being in nature.     4     Just be in the moment. Listen to the songs of the birds, breathe in some fresh air, soak in the warm rays of the sun. Did you know that Vitamin D — which we can get from sunlight — is amazing for our mind, body, and soul?

    5     One of the best ways to unplug is to learn a new hobby. Read a book (a paperback not an e-book), listen to some music on your radio or vinyl record player, cook with your loved one, or create some art. Keep yourself engaged; this way you won’t get the time to constantly check your phone.

3 . Survivor bias (偏见，偏差), occurs when you tend to assess successful outcomes and disregard failures. This sampling bias paints a more promising or even misleading picture of reality.

Survivor bias is a sneaky problem that tends to slip into analyses unnoticed. For starters, it feels natural to emphasize success, whether it’s entrepreneurs, or survivors of a medical condition. We focus on and share these stories more than the failures.

Think about the famous college dropouts who became highly successful, such as Mark Zuckerberg, Steve Jobs, and Bill Gates. These successful examples might make you think a college degree isn’t beneficial. However, that’s survivor bias at work! These famous individuals are at the forefront of media reports. You hear more about them because they are extraordinary. You’re not considering the millions of other college dropouts that aren’t rich and famous. You need to assess their outcomes as well.

Survivor bias has even occurred in medical studies about severe diseases. Younger, healthier, and more fit patients tend to survive a disease’s initial diagnosis more frequently. Hence, they are more likely to join medical studies. On the contrary, older, weaker patients are less likely to survive long enough to participate in studies. Consequently, these studies overestimate successful disease outcomes because they are less likely to include those who die shortly after diagnosis.

Undeniably, successful cases are usually more visible and easier to contact than unsuccessful cases. However, focusing on the high-performing successes and disregarding other cases introduces survivor bias. After all, you’re leaving out a significant part of the picture as it’s harder to collect data from the less successful members of a population. Incomplete data can affect your decision-making process. Put simply, survivor bias produces an inaccurate sample, causing you to jump to incorrect conclusions.

To minimize the impact of survivor bias, you should find ways to draw a representative sample from the population, not just a few of successful samples. That process might call for more expense and effort, but you’ll get better results.

4 . Please sit down and enjoy your meal. Just don’t talk about it.

These are the requirements at a popular dining party that is known as “silent dinners”. It encourages people who take part in the dining party not to speak for one to two hours and not to use electronic devices. Instead, the idea is to just on the food.

“Silent dinner parties are fast growing, ” said Honi Ryan, who has hosted 32 silent dinner parties in 11 cities across eight countries, including Germany, Australia and the United States. “The way we communicate is changing so fast that we need to stop and think about it. ”

According to a 2013 nationwide survey, restaurant noise came in second only to poor service among customer (顾客) complaints. And 19 percent of diners who took part in the survey said noise and crowds disturbed them most while eating out.

Though silent dinners may seem curious, the idea is not a new one. Yogis (瑜伽信徒) have long enjoyed silent meals as part of a deepened practice. In fact, it was a trip to a temple (寺庙) in India by a man that encouraged one Brooklyn restaurant recently to add a silent dinner to its event programming.

“We’ll make a small speech at the beginning of the meal to make sure everyone understands what is happening and ask them not to speak or use their mobile phones for at least an hour, ” said EAT Greenpoint owner Jordan Colon. And background music will be turned off, too.

“It’s funny; when I first opened EAT, I didn’t play music for some time and people had very different reactions (反映) to that,” said Colon. “Some people who come out to eat are ready to party, but it was so quiet without music. But I wanted to create an environment that makes you relaxed. ”

Although personal reactions to a silent dinner may be various, in general they are more likely to get into a lot of talk afterwards, said Ryan. “At the end of the night people always have a lot to say about silence. But the most reaction is that there is always a good laugh.”

7 . Experts say over half of the world’s seven thousand languages are in danger of disappearing. Every two weeks one language disappears.

Sometimes a language disappears immediately when the last person speaking it dies. Or, a local language might disappear more slowly. This happens when an official language is used more often and children stop learning the local language of their parents. Official languages often represent a form of control over a group of people.

Throughout history, the language spoken by a powerful group spreads across a civilization. The more powerful culture rarely respects the language and culture of smaller groups. Smaller cultures lose their local language as the language of the culture in power has a stronger influence.

Experts say protecting languages is very important for many reasons. Languages contain the histories, ideas and knowledge of a culture. Languages also contain valuable information about local medicines, plants and animals.

Many endangered languages are spoken by native cultures in close contact with the natural world. Their ancient languages contain a great deal of information about environmental systems and species of plants and animals that are unknown to scientists. As the last speakers of a language die off, the valuable information carried within a language also disappears. Language is, in many ways, a window to the mind and the world.

Any hope for protecting languages can be found in children and their willingness to learn. It is these young people who can keep this form of culture alive for future generations.
