According to Pollitz, insurers and insurance brokers would have a strong incentive to nudge sicker or older individuals or small groups toward the exchange, skewing the risk pool there and driving up premiums. "You just have to cherry-pick a little bit to be really profitable," says Pollitz. Both the House and Senate plans call for regulations and rules to prohibit this. But, as Jacob Hacker, a health-policy expert at Yale University, puts it, "The real concern comes down to having adequate resources for enforcement. It's one thing to have rules and another thing to make sure insurance...
...agent works a little differently than the bisphosphonates, which are designed to paralyze bone-destroying cells - cells that increase in number as people age. While the body continually destroys and replaces bone tissue throughout life, the destruction eventually begins to overtake the construction, and the result in older age is a patchier, weaker type of bone that is more prone to breaking. While bisphosphonates block the activity of bone-destroying cells, denosumab prevents new ones from forming altogether. The end result is a tipping of the bone balance away from bone destruction and toward bone formation. Early studies in mice...

...conventional wisdom that exercise is essential for shedding pounds is actually fairly new.

They less often develop cancer, diabetes and many other illnesses. But the past few years of obesity research show that the role of exercise in weight loss has been wildly overstated. (Read...
...Sure. It does plenty. In addition to enhancing heart health and helping prevent disease, exercise improves your mental health and cognitive ability. A study published in June in the journal Neurology found that older people who exercise at least once a week are 30% more likely to maintain cognitive function than those who exercise less. Another study, released by the University of Alberta a few weeks ago, found that people with chronic back pain who exercise four days a week have 36% less disability than those who exercise only two or three days a week...
