Paragraph: A small Swiss study released on Monday showed that walking up and down stairs for three months, without recourse to the lift, increased levels of fitness dramatically. In fact, the improvement in aerobic capacity was equivalent to a 15 percent fall in the risk of dying prematurely from any cause. Subjects also saw marked reduction in waist size, body fat, blood pressure and cholesterol all of which are known risk factors for heart disease. Philippe Meyer of the University Hospital in Geneva studied 69 employees of the university with a sedentary lifestyle, defined as less than two hours of exercise a week and fewer than 10 flights of stairs climbed a day. After not using elevators for 12 weeks, they increased their use of stairs to an average of 23 stories ascended or descended a day from five before, with a resulting sharp increase in fitness levels. "This suggests that stair climbing at work may have major public health implications," Meyer told the annual meeting of the European Society of Cardiology. "However, the results of the pilot study need to be confirmed in a larger randomized controlled trial." Claim: Take the stairs for a healthy heart.

Ex Output:
Using the stairs at work instead of taking elevators could be a life saver.

Paragraph: The Texas woman's name is Cathy Flanders and she has been on a crusade to bring the problem of indoor pollution from candles to the forefront. She has filed a lawsuit against the store that sold her candles which she says resulted in toxic levels of lead in her home and with serious medical consequences on her family. Regardless of the merits of her case, it is true that indoor pollution from certain kinds of candles is becoming a focus of research and is one of the hot topics right now among professionals concerned with health issues in the home. Not all the researchers are focused on lead and there are some who say they feel the danger from lead is reduced by the fact that U.S. candle makers have not used lead in candles for more than 25 years. There is increased focus on what researchers say is a significant contribution of candles to soot residue in buildings, more than has previously been realized, and to what extent that soot can contribute to health problems. While that is being studied, pollution experts recommend choosing candles from U.S. manufacturers that are made of hard wax, have low aromatic properties, burn with a low, even flame and with wicks that burn down evenly with the rest of the candle. They also recommend keeping burning candles out of drafts and not allowing an extinguished candle to continue emitting smoke. For more information: CNN Article about Cathy Flanders Article about Black Soot in the Home from the Environmental Illness Society of Canada Comments Claim: An email is making the rounds that talks about a woman in Texas whose family has experienced a variety of health problems which she says are due to the lead content of some candles. The email warns that burning candles in the home can lead to health problems.

Ex Output:
Beware of potential pollution from certain candles
