Jane was running late. Jane, 25, had a lot to do at work, plus visitors on the way: her parents were coming in for Thanksgiving from her hometown. But as she hurried down the subway stairs, she started to feel uncomfortably warm. By the time she got to the platform, Jane felt weak and tired—maybe it hadn't been a good idea to give blood the night before, she thought. She rested herself against a post close to the tracks.

    Several yards away, Tom, 43, and his girlfriend, Jennifer, found a spot close to where the front of the train would stop. They were deep in discussion about a house they were thinking of buying.

    But when he heard the scream, followed by someone yelling, "Oh, my God, she fell in!" Tom didn't hesitate. He jumped down to the tracks and ran some 40 feet toward the body lying on the rails. "No! Not you!" his girlfriend screamed after him.

    She was right to be alarmed. By the time Tom reached Jane, he could feel the tracks shaking and see the light coming. The train was about 20 seconds from the station.

    It was hard to lift her. She was just out. But he managed to raise her the four feet to the platform so that bystanders could hold her by the grins and drag her away from the edge. That was where Jane briefly regained consciousness, felt herself being pulled along the ground, and saw someone else holding her purse.

    Jane thought she'd been robbed. A woman held her hand and a man gave his shirt to help stop the blood pouring from her head. And she tried to talk but she couldn't, and that was when she realized how much pain she was in.

    Police and fire officials soon arrived, and Tom told the story to an officer. Jennifer said her boyfriend was calm on their 40-minute train ride downtown-just as he had been seconds after the rescue, which made her think about her reaction at the time. "I saw the train coming and I was thinking he was going to die," she explained.

    You get anxious if there's no wifi in the hotel or mobile phone signal up the mountain. You feel upset if your phone is getting low on power and you secretly worry things will go wrong at work if you're not there. All these can be called “always on” stress caused by smart phone addiction(上瘾).

    For some people, smart phones have freed them from the nine-to-five work. Flexible working has given them more autonomy (自主权) in their working lives and enabled them to spend more time with their friends and families. For many others, though, smart phones have become cruel masters in their pockets, never allowing them to turn them off and relax.

    Pittsburgh-based developer Kevin Holesh was worried about how much he was ignoring his family and friends in favor of his iPhone. So he developed an app — Moment — to monitor his usage. The app enables users to see how much time they're spending on the device(设备) and set up warnings if the usage limits are broken. “Moment's goal is to promote balance in your life,” his website explains. “Some time on your phone, some time off it enjoying your loving family and friends around you.”

    Dr. Christine Grant, an occupational psychologist at Coventry University, said, “The effects of this ‘always on' culture are that your mind is never resting, and you're not giving your body time to recover, so you're always stressed. And the more tired and stressed we get, the more mistakes we make. Physical and mental health can suffer.”

    And as the number of connected smart phones is increasing, so is the amount of data. This is leading to a sort of decision paralysis (瘫痪) and is creating more stress in the workplace because people have to receive a broader range of data and communications which are often difficult to manage. “It actually makes it more difficult to make decisions and many do less because they're controlled by it all and feel they can never escape the office,” said Dr. Christine Grant.

    We all know that exercise is good for your health. But some kinds of exercise may be better than others.

    Running, for example, may help to protect against heart disease and other health problems. Running may also help you live longer. Researchers say it is not important how far you run. It also does not matter how fast or even how often you run. As advertisements for the running shoes Nike say, “Just Do It.”

    Recently researchers studied more than 55,000 adults. About one-fourth of the adults reported running regularly. The study found these runners were considerably less likely than non-runners to die of any form of disease, including heart disease. In fact, the runners lived, on average, three years longer than the non-runners.

    This study lasted 15 years. During that time, more than 3,400 of the individuals died. About 1.200 of the deaths were linked to heart disease, hear, attack or stroke.

    One of the researchers is a man named D.C. Lee, a professor of Iowa State University Compared to non-runners, he said, runners showed a much lower risk of dying from some diseases. “Compared to non-runners, runners showed 30 percent lower risk of death by any causes, including heart attack, stroke and cancer. Also, runners compared to non-runners showed 45 percent lower risk of death by cardiovascular diseases（心血管疾病）, including heart attack and stroke.”

    D. C. Lee and the other researchers found that speed, distance and how often one runs made little difference in reducing the risk of death. The runners in the study averaged between 10 and 16 kilometers per hour. Mr Lee said slower runners and those who only ran once or twice a week were helped nearly as much as those who ran faster and further. “And also we looked at the inning over time and we found that persistent runners（over six years）showed the biggest benefits, as well.”

    Young people's mental health is of increasing interest and concern to researchers, policymakers, and families alike－but can treating teenagers' mental health problems also improve the wellbeing of their parents? New research suggests that it can. The study, conducted by Kelsey Howard, a doctoral candidate at Northwestern University, found that regardless of which treatment teenagers were using for their depression, the mental health of their parents improved too.

    Older findings say that there is a link between mothers' depression and major depression in their teenagers, although it seems not to be biological. However, the latest research suggests that the relationship between parents' and their children's mental health might work in the other direction too.

    While Howard's research hasn't evidenced a clear reason for this trend, she told The Atlantic: “If the family members interact with (交往) each other well, the kid will be more pleasant to be around and make less negative statements, which will affect how other family members think.”

    Tom Madders, director of campaigns at YoungMinds, told HuffPost UK that for parents, watching their children go through mental health problems can be difficult, especially if they feel responsible. Madders also noted that parents often make big lifestyle changes, say, giving up their jobs, to support their children with depression, particularly in cases where their children have to leave school because of their mental health problems. However, Madders thought this can only make things worse. “Parents' sacrifice adds pressure to the delicate shoulder owners,” he said.

    The process of waiting to get treatment can also be an added stressor: “Every day we get calls to our helpline from parents whose children have been waiting months for an initial assessment, or left on long waiting lists for treatment that they need … that's why it's important that the Government commits to long-term extra investment in children's mental health services.”

    Check out our tsunami (海啸) facts and lean some interesting information related to these great walls of water that can cause so much destruction. Find out what causes tsunamis and read about some notable recent examples of tsunamis that have occurred around the globe.

    Tsunamis are huge waves of water that are usually caused by earthquakes or volcanic eruptions.

    As a tsunami approaches the shore, water may move back from the coast. If it is shallow enough, the water may be pulled back hundreds of meters. If you are in the area, observing this is a good indication that a tsunami is on the way.

    Regions in tsunami danger zones often have warning systems in place to give people as much time to evacuate (撤离) as possible.

    When tsunamis hit shallow water (often near the coast), they slow down but increase in height.

    An earthquake in the Indian Ocean off Indonesia in December 2004 caused a tsunami that killed over 200, 000 people in 14 countries.

    In March 2011, the Tohoku earthquake off the eastern coast of Japan caused a tsunami that was a major factor in the death of over 15, 000 people.

    The tsunami waves created by the Tohoku earthquake reached heights of over 40 metres (131feet) in mine areas, wiping out coastal towns and causing a number of nuclear accidents.

    The Japanese word "tsunami" literally means "harbour wave".

    Tsunamis are sometimes referred to as tidal waves but this term has fallen out of favour because tsunamis are not related to tides.
