On a stormy day last August, Tim heard some shouting.Looking out to the sea carefully, he saw a couple of kids in a rowboat were being pulled out to sea.

Two 12-year-old boys, Christian and Jack, rowed out a boat to search a football.Once they’d rowed beyond the calm waters, a beach umbrella tied to the boat caught the wind and pulled the boat into open water.The pair panicked and tried to row back to shore.But they were no match for it and the boat was out of control.

Tim knew it would soon be swallowed by the waves.

“Everything went quiet in my head,” Tim recalls(回忆).“I’m trying to figure out how to swim to the boys in a straight line.”

Tim took off his clothes and jumped into the water.Every 500 yards or so, he raised his head to judge his progress.“At one point, I considered turning back,” he says.“I wondered if I was putting my life at risk.” After 30 minutes of struggling, he was close enough to yell to the boys, “Take down the umbrella! Let’s aim for the pier(码头),” Jack said.Tim turned the boat toward it.Soon afterward, waves crashed over the boat, and it began to sink.“Can you guys swim?” he cried.“A little bit,” the boys said.

Once they were in the water, Tim decided it would be safer and faster for him to pull the boys toward the pier.Christian and Jack were wearing life jackets and floated on their backs.Tim swam toward land as water washed over the boys’ faces.

“Are we almost there?” they asked again and again.“Yes,” Tim told them each time.

After 30 minutes, they reached the pier.

If doctors want to test you for something, they’ll usually take a blood or urine sample (尿样). But wouldn’t it be much more convenient if they just asked you to breathe through a special instrument?

In fact, your breath can say a lot about you. In traditional Chinese medicine, doctors draw a conclusion about the health state of a patient based on the smell of his or her breath; trained dogs and rats can identify the smells of the breaths of people suffering from certain cancers; traffic police also monitor drivers’ alcohol consumption by testing their breaths.

Just like blood and urine, your breath contains lots of “ metabolites ” --- the waste chemicals that the body produces, which vary from person to person. They are like personal health fingerprints, which is why scientists sometimes call them “ breath prints”, according to Science Daily.

Compared to blood or urine testing, breath testing takes only seconds instead of hours, and it requires neither a needle nor a container to hold the body fluids (体液). This means the test can be taken frequently to better detect early signs of diseases and monitor the progress of a medical treatment.

On the other hand, as an identifier, you might think that breaths are not as reliable as fingerprints since they might change based on what you eat. However, researchers in Zurich, Switzerland mapped 11 healthy volunteers’ chemical patterns by having them breathe through a special instrument, and they found that each pattern was unique and the patterns didn’t change much throughout the day, reported BBC.

“Our goal is to develop breath analysis to the point where it becomes competitive with the established analysis of blood and urine,” said Malcolm Kohler, professor at the University Hospital Zurich.

Listening to music an help me focus better. Since I discovered it two years ago, I’ve used music to get through boring work or to focus creatively. I’ve found that it can make even the dullest jobs enjoyable and help clear mental blocks to creativity.

I first noticed the good effects of music while playing video games. It was a few days before Christmas in 2012 and I was playing online video games. My parents had just given me a new MP3, so I decided to listen to music through the headphones while I played. After a few minutes I noticed a great change in my style of play. I was playing more naturally. The music relaxed me, and, to a certain extent, distracted me from the game, allowing my subconscious(潜意识的)talent to come through. The music also helped me block out the outside world. With those headphones on I was like a machine, moving from one task to the next without unnecessary thoughts or actions.

Music can also have a great effect on mood, if I’m in a bad mood at work, I’ll listen to some of Bob Marley’s and get down to business. It always takes my mind off what I’m doing and makes me a happier person. The same is true of classic rock. One summer, I did a boring job collecting bottle openers by hand. Without a radio playing classic rock in the background, I would have hated life.

Listening to music with relaxing rhythms and a positive message helps you forget your work and think happy thoughts. But the results you see will depend heavily on your personal tastes. Experiment with the types of music you listen to during certain tasks. By trial and error you’ll finally discover your best choice. I’m always looking for new concentration aids, so I’d love to know what type of music works best for me.
