When teenagers drink, it's all too often all out, downing five or more beers in a session. But some teenagers are drinking even more, a study finds, boosting the upper limits of binge drinking to 15 drinks or more.

In a poll of high school seniors, 20 percent said they'd had five or more drinks in a row in the past two weeks. That's what health officials consider binge drinking.

But 10 percent said they'd had 10 or more drinks at a time, and 5.6 percent said they'd had 15 or more drinks.

Scientists claim they have evidence that explains why lifestyle changes known to be good for you — low-fat diets, exercise, reducing stress — can lengthen your life.

Based on a small, exploratory study, researchers say these good habits work by preventing chromosomes in our cells from unraveling. Basically, they assert that healthy living can reverse the effects of aging at a genetic level.

People who lose their jobs and the health insurance tied to them will have new coverage options when the Affordable Care Act's marketplaces open in October.

But consumer advocates are concerned many of these unemployed people may not realize this and lock themselves into pricier coverage than they need.

When the Affordable Care Act was working its way through Congress, Gary Lauer was nervous. Part of the bill sounded grim. It said people could buy required health coverage online, but only through websites run by state and federal governments.

"That was going to pretty much delete us from the landscape," he says.
