Several years ago, my boss fainted due to exhaustion after staying up late to catch up on work. She banged her head and ended up with five stitches (缝针)―and became what she calls a “sleep evangelist (传教士).” Now she leaves her phone charging in another room when she goes to bed and encourages her friends to do the same.

“I sent all my friends the same Christmas gift―a lovely alarm clock―so they could stop using the excuse that they needed their very attractive iPhones by their beds to wake them up in the morning.” she said.

If your phone wakes you up in the morning, it may also be keeping you up at night. A 2008 study showed that people exposed to mobile radiation took longer to fall asleep and spent less time in deep sleep. “The study indicates that during laboratory exposure to 884 MHz wireless signals, components of sleep believed to be important for recovery from daily wear and tear are severely affected,” the study concluded.

A quarter of young people feel like they must be available by phone around the clock, according to a Swedish study that linked heavy cellphone use to sleeping problems, stress and depression. Unreturned messages carry more guilt when the technology to deal with them lies at our fingertips. Some teens even return text messages at midnight.

Most of us choose not to set limits on our nighttime availability. Nearly three quarters of people from the age of 18 to 44 sleep with their phones within reach, according to a 2012 Time poll. That number falls off slightly in middle age, but only people aged 65 and older are leaving the phone in another room as common as sleeping right next to it.

【推荐3】Many on the Mountain

We often see people waiting in lines at supermarkets, theatres and amusement parks. Surprisingly, some people even have to wait in line at the summit (顶峰) of Qomolangma in the Himalayas.

The best time to climb the Himalayas is during the months of April and May, as well as some days in September and October. "In these periods of recent years, the path contains rocks and deep crack from melting ice due to the warm weather, which make expeditions up the mountain more dangerous," said Apa, an experienced Nepalese guide. During this year's climbing season, crowds of climbers became stuck in a long line near the summit. The line is above the mountain's highest campsite—about 8,000 meters above sea level.

However, most people can only spend a few minutes at the summit without extra oxygen supplies. Twenty-one mountaineers have died in the Himalayan mountains so far this year, according to Gripped, a magazine dedicated to mountain climbing. Eleven of these climbers died on Qomolangma.

This death count marks a four-year high. Overcrowding, inexperience and poor weather have been the most common causes of death, USA Today reported.

After these tragedies, one question remains: Why do so many people risk their lives to climb the mountain? The answer differs from climber to climber. Studies suggest that people who take risks tend to perceive themselves differently than people who avoid risky activities. But for adventurers who are drawn to the Himalayas, reaching the summit of Qomolangma is a lifelong dream, according to Discovery News.

"Qomolangma is like a light to bugs that attracts people once they hear about it. It represents the ultimate for many people," US mountaineer Alan Arnette said. Technological advances have also encouraged more people to climb the mountain. People can get high-tech safety equipment more easily than before. And with the internet, climbers know better than ever about how to reach the summit safely, Yahoo Travel noted.

【推荐1】A hobby is any activity a person likes to do in his spare time. So those who get busy in their activity never get bored in their free time. Hobbies vary from person to person. Hobbies are of different kinds. They can be indoors or outdoors. Some are costly and some are cheap. Pursing a particular hobby is a matter of personal choice.

My favorite hobby is coin collection. It is also one of the oldest hobbies of the world and is also called “hobby of the Kings”, as in the old times, it was only done by kings and elite(精英)class of the society. It started for me some years back when my father used to come back from his foreign tours and give me coins of different countries. I started collecting then in my money box and after that I always used to wait for my new coins as much I used to wait for my father.

Since then, it has become my favorite hobby. This hobby has given me information about different countries of the world. I have got to know about important personalities of the different countries.

This hobby has made me be responsible to take care of important things at very young age. I have learnt dealings of different currencies(货币)on my foreign tours and save money for my favorite hobby. I feel extreme pleasure in showing my collection to others. It has also taught me this lesson that A LIFE WITHOUT A HOBBY IS JUST LIKE FOOD WITHOUT SALT.

【推荐3】Have you ever thought of quitting your job when you feel exhausted? Maybe most of you would say “yes”. After a particularly busy period at work, I decided to get away from it all by going on a hike in the mountains in southern France.

Before I left, I read an interesting story in a magazine. It read, “Once, while I was riding on a crowded bus, the man sitting next to me threw his cell phone out of the window when his phone rang. I was surprised. He looked at me, shrugged (耸耸肩) and looked away. I had no idea whether it was his or stolen or whether he even knew what a cell phone was or not, but he clearly wanted to be free of it, because it clearly troubled him.”

Billions of people across the world use cell phones. Though cell phones are a wonderful way for communication, they often do the exact opposite. Using cell phones can increase stress within families and friends.

So when I recently returned home, I got rid of my cell phone. Now I go outside without taking my phone with me. I’ve noticed things in my neighborhood I never noticed before, such as gardens. I’ve met new people, started conversations with neighbors I didn’t speak to before and talked with some of my friends face to face instead of chatting over the phone.

Instead of keeping me off from the world, stopping using my cell phone has helped me get even closer to my family and friends.
