Ida Nelson was relaxing herself in her sister’s sauna (桑拿室) when she heard the sound of a small airplane circling the nearby airport.

It was 11: 30 at night in a remote village with a population of 70, and, as she told the newspaper reporter, “Any time a plane flies over that late, you know something is wrong.” Nelson and her sister leaped out of the sauna, ran to the window, and saw the problem — the airports runway lights were out. Nelson threw on some clothes, jumped into her jeep, and floored it to the airport, where she found a local pilot trying to turn on the lights manually.

“Normally, if you push the button 10 or 15 times, the lights will just light up,” Nelson told the reporter. Not this time. Meanwhile, she and the pilot learned of the plane’s urgent mission — it was a helicopter, there to transport a seriously ill local girl to the nearest hospital, 280 miles away in another city.

Nelson had a plan. Driving her jeep to the end of the runway, she shone her headlights on the road for the plane to follow. Great idea, but it wasn’t enough. More light was needed, so a neighbor called nearly every home in the village — 32 of them.

Within 20 minutes, 20 vehicles arrived at the airport, many of the drivers still in pajamas. Following directions from the helicopter pilot, the cars lined up on one side of the runway. The helicopter made its final approach and, guided by the headlights, landed safely. The young patient was loaded onto the aircraft, and the plane immediately took off again. Her illness was never publicly known, but she has since been recovered.

Without them, the girl might not have made it. However, for Nelson, it was only a small deed.

When you set a foot outside of your door to drop trash, go to a social event or go for a walk, thoughts like “I hope I don’t see anyone I know” or “please don’t talk to me” may run through your mind. I’ve also said such things to myself. Sometimes the last thing you want to do is to talk with someone, especially someone new.

Why do we go out of our ways to avoid people? Do we think meeting new people is a waste of time? Or are we just lazy, thinking that meeting someone new really is a trouble?

Communication is the key to life. We have been told that many times. Take the past generations, like our parents, for example. They seem to take full advantage of that whole “communication” idea because they grew up talking face to face while Generation-Y grew up staring at screens. We spend hours of our days sitting on Facebook. We send messages to our friends and think about all of the things we want to say to certain people that we don’t have the courage to actually do in reality.

Nowadays, we are so caught up in our little circle of friends — our comfort zone. We love it that they laugh at our jokes, understand our feelings and can read our minds. Most importantly, they know when we want to be alone. They just get us.

Holding a conversation with someone new means agreeing with things that you don’t actually believe and being someone you think they want you to be — it is, as I said before, a trouble. It takes up so much energy, and at some point or another, it is too tiring.

But meeting new people is important. Life is too short, so meet all the people you can meet, make the effort to go out and laugh. Remember, every “hello” leads to a smile — and a smile is worth a lot.

Gorillas (大猩猩) in films such as King Kong and Tarzan are wildly beating their chests when under threat. Researchers have tried to find out what the behavior might mean, and they doubt that the gorillas exhibit this behavior not to start fights, but to prevent themselves — and chest-beating could be used to advertise their body size to other gorillas.

Scientists observed 25 wild male mountain gorillas for over 3,000 hours. The research team used audio (音频) equipment to record the sound frequency, rate, duration, and amount of chest beats. To determine each gorilla’s size, the researchers used cameras to photograph and measure each gorilla’s back.

Although the rate, duration, and amount of beats did not correlate with the size of the gorillas, sound frequency did , the researchers report. The team also noticed that larger gorillas produced deeper-tone chest drumming. Previous research has shown that a gorilla’s larger body size is linked to reproductive success and social rank. The chest-beating could be a way for the gorillas to advertise their size to others and, in turn, avoid fights that could result in serious injury or death.

Though gorillas can obviously observe size just by getting a good look at others, the researchers suggest chest beating is copper-bottomed when trying to communicate through a thick forest. The sounds gorillas created by beating their chests are powerful enough to travel long distance through thick forests and signal others their size and fighting ability.

Animal expert Anna Nekaris says it would be interesting to see if smaller gorillas can imitate the deep tones of larger ones in future studies. Nekaris says, “For now, the researchers will continue to study chest-beating to see if the action can pass on other information, such as dominance rank, sex, and individual identity, to nearby gorillas.”
