"The caffeine content of energy drinks varies over a 10-fold range, with some containing the equivalent of 14 cans of Coca-Cola. Yet the caffeine amounts are often unlabeled, and few include warnings about the potential health risks of caffeine intoxication," Roland Griffiths writes in The Gazette of Johns Hopkins University, where the study took place.
Sure, you know walking is good exercise. But here's something you might not realize: You can give your waistline (and other body parts) a serious trimming by tweaking that walk around the block.
Walking up an incline can help you lose pounds faster than on flat terrain.
The three women below each walked off at least 35 pounds, much of it around the middle, using one of these secret weapons: plyometrics, hills, or intervals.

That runner's high may translate into a lot of other long-lasting health benefits, a new report from an ongoing study suggests. Researchers have found that regular jogging, or any consistent aerobic exercise, in middle age and late in life may reduce people's risk of disabilities and help them live longer and healthier.
Geezer loves naps as much as the next lazy person, but even he has found the best way to beat the blahs is often a quick bike ride.

In a study published in the December issue of JAMA (Journal of the American Medical Association), researchers took on this issue and decided to find out how important fitness level is, as opposed to body fat levels, when it comes to mortality. What they found is actually pretty amazing. They followed more than 2000 seniors over a period of years and found that those who died sooner had lower fitness levels and more cardiovascular risk factors than survivors. But, what was interesting was that there were no significant differences in the body fat levels between decedents and survivors.
