Why would human beings waste a third of their lives sleeping when they could be doing more important things like looking after their families or working? Some scientists believe sleeping helps recharge the body, while others think it is important for strengthening newly-formed memories. Now, there is new evidence which suggests that the purpose of sleep may be to forget some of the millions of new things we learn each day.
The neurons in the human brain consist of fibers called dendrites(树突). These grow as we learn new things and connect the brain’s cells to each other at contact points called synapses(突触). The larger the dendrites become and the more cells they connect, the more information we store.
In 2018, Giulio Tononi and Chiara Cirelli, both biologists at the University of Wisconsin-Madison, suggested a new idea: The things our brains learn each day result in so many synapses that things start to get a little messy. Sleeping allows us to sort through(整理) the “noise” and dispense all the unnecessary information, leaving behind only the most important memories.
Recently, the university’s research has provided direct evidence to support the theory. The experiment involved analyzing 6,920 synapses in the brain shavings from two groups of mice over a four-year period; one group had been allowed to sleep, while the other had been kept awake and entertained with toys. The researchers discovered that the brain shavings of the sleeping mice had nearly 20 percent fewer synapses than those that had been kept awake and entertained.
It was also evident during the study that the brain does not shave every synapse. 20% of neurons remained unchanged; these were most likely well-established memories. Therefore, although we may be sleeping to forget some of what we’ve learned, the brain “forgets”in a smart way.
Most researchers believe clearing our brains is not the only purpose of sleep. Resting our minds and bodies has also been found to help with other biological functions like strengthening our immunity. Though scientists may never agree on a single reason, they are all sure of one thing－a good night’s rest is essential for our health. So try and spend at least a third of your day sleeping!

From now on, never spend your precious time thinking of reasons for your failures and shortcomings. Instead, realize that the seeds of success were planted within you when you were born. Only you have the power to make those seeds grow.
The seeds, and the power to grow them, are contained in the most awesome machine ever created：the human mind. Success is a choice and not a chance. You were born a winner. You were born rich. You can be a success if only you make the right choice.
You cannot be successful without first developing your self-esteem. Your level of self-esteem is always based on the degree of control that you are able to exercise over yourself, and thus over your life. People with low self-esteem are people who do not believe that they have any power, or responsibility for their lives. They are the perennial(长期的) victims and martyrs. They are leaves tossed(摇摆) by the winds of chance blown about with any sudden change in the weather.
You can exercise control over your life only to the degree that you believe that you are responsible for everything that happens in your life. Failures think that everything happens by accident and chance. Successful people realize that they are responsible.
Everything happens as a result of something. If we can identify the cause, we can control the effect. We are responsible for what we choose to think and believe. One generally rises to the level that one expects. We are responsible for setting our expectations. Our success is dependent upon our level of confidence.
If you associate with positive-thinking people, you are definitely going to achieve success. On the contrary, the opposite happens. We are responsible for finding, planting, and nurturing the seeds that contain future victory, born from setbacks.
In short, in all areas of your life, whether they be financial, physical, emotional, or spiritual, you are responsible. Once you recognize this, accept it, and firmly believe it, you are on the road to success.

The term “graffiti” is an Italian word meaning scratching or scribbling(乱涂). It entered the English language in the 1850s, specifically to describe the casual wall writing that experts found in Pompeii and the Roman tombs. Originally a term used only in ancient scribbling, the word has undergone considerable expansion of meaning in the past 75 years so that it now refers to any written message on a wall. Graffiti are characterized by their casualness; if they were more formal, they would be known as inscriptions(铭文).
The first piece of graffiti was found on one of the walls of the city Pompeii, which was destroyed by the eruption of Mount Vesuvius in 79 AD. It was one of 1,600 pieces of graffiti uncovered in Pompeii during a dig in the 19th century. Not surprisingly, there is much evidence of graffiti writing on the pyramid and temples of ancient Egypt. It is likely that ever since people have had walls and materials to scratch or paint with, they have been engaged in this simplest form of communication.
The writing of graffiti gives people a unique opportunity to achieve some kind of public audience. Thus short poems, declarations of love, pieces of political and revolutionary polemic(论战), and criticisms of institutions and people form a significant part of graffiti.
Apart from its usefulness in terms of self-expression, graffiti is also a valuable source for historians. There is always the possibility that historical events may be recorded by the presence of graffiti. Perhaps the most interesting example of this is the graffiti relating to the gladiatorial(角斗士) contests held in Pompeii. Graffiti can also give us a unique view into the daily life and customs of a people, for its casual expression encourages the recording of details that more formal writing would tend to ignore.
In the late 1970s, graffiti became popular. A thought written on a toilet wall in Wolverhampton can now be read in Chicago or Adelaide. In its own way, this is probably the most fascinating example of McLuhan’s concept of “the global village”. We now have a worldwide toilet wall.
