1 . We’ve all heard the age-old advice to drink eight cups of water a day. But if you fall short, don’t worry: That advice is probably wrong anyway. That’s according to new research. which found that for most healthy adults, there is no real benefit to drinking eight cups of water a day.
The advice to drink eight cups of water a day comes from a 1945 recommendation from the Food and Nutrition Board of the National Research Council, which encouraged adults to consume about 64 ounces of water daily. The recommendation referred to a person’s total daily intake of water, including from all their foods and drinks, but it was widely misinterpreted to mean that people should drink 8-ounce glasses of water every day.
To see how much water people really need, Herman Pontzer, a professor at Duke University and his co-authors analyzed data on 5,600 people. The participants were tracked with a gold-standard technique called “doubly labeled water”, which uses water laced with tracers that can be used to track the body’s production of carbon dioxide, allowing the researchers to get precise measurements of the participants’ daily energy consumption.
The researchers determined how much water the participants lost and replaced each day. a measurement known as water turnover (水周转率). They found that a person’s daily water turnover was largely determined by their size and their level of body fat, which contains less water than muscle and other organs. The more “fat-free” mass a person has, the more water they need.
The research showed that how much water you need changes over your lifetime. In general, our water needs peak between the ages of 20 and 50 and then decline in parallel with the slowing down of our metabolisms (新陈代谢).
So how much water should you drink? The answer is simple: Drink when you’re thirsty. Prioritize water, and try to avoid sugary drinks, which can cause metabolic problems. “If you’re paying attention to your body and drinking when you feel like you need to, then you should be fine,” Pontzer said.

POOR DAVY
It was break time at the village school, surrounded by acres of vibrant flower fields. The bell had rung, and the children had run out into the bright sunshine, wild with laughter and fun.
All the children but poor Davy. He came out last, very slowly, but he did not laugh. He was in trouble, and the bright, golden sunlight failed to cheer him up.
As he walked across the yard, his eyes fell upon the vibrant flowers that bloomed in vivid colors among the rolling green fields. All kinds of violets (紫罗兰) nodded their heads in the breeze, as if trying to cheer him up. Yet Davy’s heart was too heavy to appreciate their beauty.
He walked across the fields, and sat down on a stone behind the old maple. A little bird on the highest branch sang just to make him laugh. But Davy did not notice it. He was thinking of the cruel words that had been said about his ragged (破烂的) clothes. Tears welled up in his eyes, and streamed down his cheeks.
Poor Davy had no father, and his mother had to work hard to keep him at school.
That evening, Davy took the path home that led across the fields and through the woods. The sun was setting, casting a golden hue over the flowering meadows. But Davy’s heart was still heavy, so he walked with his head bowed.
Davy did not wish to trouble his mother; so he lingered a while among the trees, and at last threw himself on the green moss (苔藓) under them. Just then, his teacher came along. She saw who it was, stopped, and then kindly asked,“What is the matter, Davy?”
He did not speak, but the tears began again to start. “Won’t you tell me? Perhaps I can help you.” she asked gently, kneeling beside him.
Then he told her all his trouble. When he ended, she said, cheerily, “I have a plan, Davy, that I think will help you.”

8 . Find your new favorite hobby
Challenging and fun hobbies have the power to make us happier and healthier. They can lead to better physical health, lower stress, greater life satisfaction, a larger social network and improve work performance.
Ask yourself how you want to feel
Hobbies present an escape—they can help you get out of your head and calm down. Ask yourself how you want an activity to make you feel. Mentally engaged? Distracted? Relaxed? Socially connected?
Start small
When people feel guilty about spending time on leisure, they experience increased symptoms of depression and anxiety. Give yourself permission to do something that you like and keep in mind that if a hobby makes you healthier and happier, everyone around you will benefit. Think of discovering new hobbies as a way to add new dimensions to your life, and enjoy the process.
Take a trip back in time
When you were a kid, what did you want to be when you grew up? The answer could point you toward an appealing hobby. Revisit some activities you loved when you were young, like drawing, putting together model kits, collecting things or building clay figures, which is really helpful to start your new hobbies.
Keep a list
Keep a list on your fridge or other things of all the things that strike you as interesting. Write down potential interests as they come to you, and you’ll have no shortage of options to explore when you’re ready.

9 . Many young Tibetan college graduates long for a stable job in the public sector after graduation, but Samdrub Norbu is an exception. The 23-year-old founder of Yangchak Art has been running a Tibetan guitar business for more than half a year since getting his degree from Tibet University last year.
Samdrub Norbu, born to a Tibetan family in Lhokha, a cradle of Tibetan civilization, is captivated by Tibetan culture. “The Tibetan guitar is what I love. That’s why I chose this business,” Samdrub Norbu said. “I don’t know what the future hold, but I am happy every day about what I have been trying so far, never feeling tired.” He has a distinctive dual motive: earning a profit while preserving Tibetan musical instrument culture.
Despite finally achieving success, Samdrub Norbu’s business activities in Tibetan instruments got off to a shaky start. While still studying in college three years ago, he opened a shop in his home county selling music al instruments. However, the business failed and he lost almost 500,000 yuan ($69,000), which had a huge impact on him and his family.
“The most pain I suffered while having difficulties was not physical, but mental,” he said. During his darkest days, his relatives—apart from his supportive mother and father—friends and even his girlfriend, abandoned him.
In spite of the failure and setbacks in life, his strong determination to fulfill his dream emboldened him once more and supported him in the success of running the same business again after his graduation. In just a few months since opening the first shop in Lhasa last year, his business has already expanded, with a second shop opening in Lhasa four months ago. The number of staff in his workshop has grown to 10.
Besides selling various Tibetan guitars, he also operates a workshop to produce them himself and runs Tibetan guitar learning courses for beginners. He aims to found an art school in the future.
“Like the Tibetan saying, ‘There is no room for sorrow in a place where one can find music and dancing’, I believe what I have been doing can bring happiness to others.”
