Does bariatric surgery save lives for those who are morbidly obese? That's been an important question as the procedure has become increasingly popular in the last decade. Some studies have shown that there is a benefit, but a new report in the Journal of the American Medical Association indicates that midlife patients are the least likely to extend their lives through the surgery.

This is the time of year when our thoughts turn to liposuction. As summer approaches, many of us are despairing that we'll ever be swimsuit ready. Could lipo be the answer to jelly bellies and cottage-cheese thighs?

Maybe not, according to a study in the journal Obesity. Researchers from the University of Colorado found that fat clings stubbornly to our poor bodies. Even when it's sucked out with liposuction, it returns – to another part of our anatomy.

You're so vain…Yes, that's you I'm talking about if you're a man at midlife who's thinking you might need a little professional help to keep looking young. According to a report released yesterday by the American Society of Plastic Surgeons, men underwent more than 1.1 million cosmetic procedures in 2010, up 2 percent over 2009 despite the recession.

Some procedures were especially popular, the report said. Facelifts for men were up 14 percent and male liposuction rose 7 percent.
