4 . HABITS FOR A HEALTHY LIFESTYLE
As teenagers grow up, they become more independent and start making their own decisions. However, during this period, it can be easy for some of them to form bad habits. These bad habits, if left unchecked, could lead to more serious ones when they become adults. For example, some of them may become involved in tobacco or alcohol-abuse, which can lead to physical and mental health problems. To prevent harmful habits like these from dominating a teenager’s life is essential. They must learn to recognise bad habits early and make appropriate changes.
To change bad habits is never easy, even with many attempts. There is a famous saying based on the philosophy of Aristotle: “We are what we repeatedly do.” In many ways, our lifestyle is the sum of choices we have made. We make a choice to do something, and then we repeat it over and over again. Soon that choice becomes automatic and forms a habit that is much harder to change. The good news is that we can change, if we understand how habits work.
According to modern psychology, we must first learn about the “habit cycle”, which works like this:
*Firstly, there is a “cue”, an action, event, or situation that acts as a signal to do something.
*Secondly, there is a “routine” , the regular action you take in response to the cue.
*Thirdly, there is the “reward”, the good thing or feeling we get from the routine.
For example, when we feel unhappy (cue), we eat lots of unhealthy snacks (routine), which makes us feel happy (reward). The reward makes us much more likely to continue the cycle, and the bad habit of relying on unhealthy snacks is formed.
To facilitate a positive change in our bad habits, we must first examine our bad habit cycles and then try to adapt them. We can do this by combining the information from our habit cycles with our own positive ideas. For example, we could try to replace a negative routine with something more positive. So, when we feel unhappy again(cue), rather than eat snacks, we could listen to some of our favourite music instead(routine), which will make us feel relaxed (reward). Aside from changing bad habits, we can also use the habit cycle to create good habits. For example, when we come to an escalator(cue), our normal routine is to ride it, but we could change this routine into something more positive by taking the stairs instead.
Many of us try to change bad habits quickly, and if we are not successful straight away, we often become pessimistic and give up. In fact, the most successful way to change is not suddenly, but over a period of time. As the Chinese philosopher Lao Zi wrote, “A journey of a thousand miles begins with a single step.” One step seems small, but it is essential. To reach the goal of change, a person must show some discipline and repeatedly take many small steps. After all, it is not easy to break bad habits.
For young people, there is plenty of time to change bad habits. However, there is no “magic pill” or delete button that will help you; you have to think about your bad habits and decide on some changes. You have the power to build a happy and healthy life full of good habits!

8 . Researchers hope brain implants will one day help people with aphasia(失语症) to get their voice back—and maybe even to sing. Now, for the first time, scientists have demonstrated that the brain’s electrical activity can be decoded and used to reconstruct music.
A new study analyzed data from 29 people monitored for epileptic seizures(癫痫发作), using electrodes(电极) on the surface of their brain. As participants listened to a selected song, electrodes captured brain activity related to musical elements, such as tone, rhythm, and lyrics. Employing machine learning, Robert Knight from UC Berkeley and his colleagues reconstructed what the participants were hearing and published their study results. The paper is the first to suggest that scientists can “listen secretly to” the brain to synthesize(合成) music.
To turn brain activity data into musical sound, researchers trained an artificial intelligence (AI)model to decode data captured from thousands of electrodes that were attached to the participants as they listened to the song while undergoing surgery. Once the brain data were fed through the model, the music returned. The model also revealed some brain parts responding to different musical features of the song.
Although the findings focused on music, the researchers expect their results to be most useful for translating brain waves into human speech. Ludovic Bellier, the study’s lead author, explains that speech, regardless of language, has small melodic differences—tempo, stress, accents, and intonation—known as prosody(韵律). These elements carry meaning that we can’t communicate with words alone. He hopes the model will improve brain-computer interfaces (BCI), assistive devices that record speech-associated brain waves and use algorithms to reconstruct intended messages. This technology, still in its infancy, could help people who have lost the ability to speak because of aphasia.
Future research should investigate whether these models can be expanded from music that participants have heard to imagined internal speech. If a brain-computer interface could recreate someone’s speech with the prosody and emotional weight found in music, it could offer a richer communication experience beyond mere words.
Several barriers remain before we can put this technology in the hands—or brains— of patients. The current model relies on surgical implants. As recording techniques improve, the hope is to gather data non-invasively, possibly using ultrasensitive electrodes. However, under current technologies, this approach might result in a lower speed of decoding into natural speech. The researchers also hope to improve the playback clarity by packing the electrodes closer together on the brain’s surface, enabling an even more detailed look at the electrical symphony the brain produces.
