...these hyperconfident opinions assume that stress is bad for your heart and that scaling back can only improve your health. But life isn't as simple as that. True, there is growing evidence that stress plays a role in cardiovascular disease, both in the buildup of fatty plaques inside the arteries, a process called atherosclerosis, and in the triggering of heart attacks. But stress is by no means as clearly defined a danger as, say, smoking, obesity or high cholesterol...
...from a surprising source, conservative Antonin Scalia, the court backed the EPA's authority to set tough new limits on the amount of ozone and fine particles (better known as soot) spewed out by trucks and power plants. These pollutants ravage the lungs and are implicated in asthma and cardiovascular disease. The high court rejected arguments by the trucking industry and its allies that Congress had delegated too much power to the EPA and that the agency must take the cost of compliance into account when setting air-quality standards. The EPA hopes to have the ozone rules finalized soon...
...recognized dance sport as a legitimate sport in 1997.) Among the many websites that serve the ballroom community, www.dancescape.TV is visited daily by tens of thousands of fans and participants.

...physically fit had about the same risk for all causes of death, over a 10-year period, as those who were of normal weight and physically fit. The study also reported, however, that men who were obese and physically fit had a 60% increased risk of death from cardiovascular disease, while those who were merely overweight and not fit had a 50% increased risk. Since about 60% of U.S. men are overweight or obese, the potential public-health impact of not maintaining normal weight could be enormous. In addition, men who were both obese and unfit were five times (rather...
...blunt pharmaceutical instrument. The drug encourages the brain to flood the synapses with the neurotransmitter dopamine?the substance your body uses to reward itself when you, say, complete a difficult assignment at the office or finish a vigorous workout. And when the brain is awash with dopamine, the whole cardiovascular system goes into sympathetic overdrive, increasing your heart rate, pulse and even your respiration. You become, after that first hit of speed, gloriously, brilliantly, vigorously awake. Your horizon of aspiration expands outward, just as in your mind's eye your capacity for taking effective action to achieve your new, optimistic...
