But athletes now know they can also get into trouble by drinking too much. Too much water intake can lower levels of sodium in the blood. The death of a 28-year-old woman following the Boston Marathon caught the attention of many runners and led to new research. Experts advise long distance runners to replace the liquids they sweat out. Their goal is to try to keep someone from not getting dehydrated by more than 2 percent of their body weight. One technique for deciding how much water you need is to get the exact numbers. Runners have to weigh themselves before and after a run to determine how much water they've lost. If their weight drops by more than 2 percent, they have not drunk enough water. Hyponatremia occurs when runners drink so much water that blood salt levels drop off. A study published last year tested 488 runners who completed the Boston Marathon and found 13 percent of them had dangerously low blood salt levels. The first sign that runners may notice is slightly swelling in the hands. They can't get their rings off, and then they might feel sick. They may not remember where they are. In fact, most runners get enough salt to get back to normal levels by eating just one meal after a run. Contrary to the old advice that runners should drink as much as they can to prevent dehydration, the new research has shown that the body is a remarkable machine that actually tells you via thirst when you need water.

Article: One person can make a difference -- purchase your copy of For America and discover simple ways to improve your life, your country, even the world. But a simple and attractive way to cut energy costs, improve air quality, and ensure public health is to grow a garden in the sky. Each time a city building is set up, the grass in that spot and trees that once reached up to the sky are replaced by a layer of asphalt or a tar roof . The lost green space can have a very real effect on a city's air temperature, air quality, and energy costs. On a summer day in most American cities, a tar roof can feel like the inside of an oven . But what if we could replace the hot roof of each skyscraper or building in a city with grass or a garden? Whether it holds vegetable gardens, wildflowers, or grasses, a green roof can lower the temperature above a building by 60 degrees, which can reduce the building's energy costs and, if used more widely, could decrease a city's total energy costs, and improve air quality and public health. But that's not all -- green roofs are a great way to handle water management in urban areas by taking in much rainfall, provide shelters for urban wildlife, and actually extend the life of the roof itself. And green roofs also do something else: they beautify the city -- whether you're on the 3rd floor or the 30th. Now that's a brilliant achievement. The non-profit group Earth Pledge is promoting a Green Roofs Program. To learn more about a green roof, just click here: EarthPledge.com.

Read the following article and select the best answer. Article: As the new semester begins,millions of college students across the country are trying hard to remember how best to write a paper-or,more likely,how best to delay that paper. _ is the thief of time and a lot of students suffer from it.They can spend whole days in the library doing nothing but staring into space,eating snacks,surfing the Internet,watching videos and looking at their pretty peers sitting around them,who,most likely,are doing nothing either. Paralyzed by their habit to procrastinate,they write micro blogs about their fears,asking their online friends if they sometimes have the same issue.But this does nothing to solve their problems. According to a recent report by the BBC,95 percent of us procrastinate at some point and 20 percent of the world's population are procrastinators,complicating their lives with their continual delaying of tasks. Procrastinators like to find excuses to justify their behavior,but BBC columnist Rowan Pelling says they are all wrong.Many procrastinators tell themselves they are perfectionists who work best under pressure.Pelling says this is nonsense,as work done at the last minute is more likely to have mistakes than work done on time. She says the behavior of procrastinators often makes them feel flustered and ashamed,inconveniences others,and annoys loved ones. Fortunately,social seientists have made tireless efforts to understand this behavioral shortcoming and offer strategies to control it.Piers Steel,a Canadian social scientist and author of The Procrastination Equation,believes humankind is"designed"to procrastinate.Nevertheless,he suggests a couple of good ways to get through the task at hand. The first one is obvious:Break the task down into small pieces and work your way through them methodically. The second is clever:Give a trusted friend a sum of money and tell them that if you don't complete the task you have undertaken by a specific time,they can keep it or donate it to a cause you hate.
