Researchers: More Exercise, Less TV Can Lengthen Life

Exercise: In the latest study to look at the effect of exercise on life expectancy, researchers suggest that just 15 minutes of exercise each day can boost the life expectancy of previously inactive people by three years, Mikaela Conley reports for ABCNews.com. But you'll have to stop watching so much TV, too, if you want to live longer, as new research finds that every hour of watching TV (and ostensibly being sedentary) can reduce your life span by nearly 22 minutes, Kristina Fiore reports for MedPage Today.  

Health Reform: In California, health lobbyists are turning out in droves to try to grab of a piece of the state's health insurance exchange, now being developed to meet national health reform requirements, Kevin Yamamura reports for the Sacramento Bee.

Deficit: Seniors should worry more about what Congress' debt-cutting "super-committee" will come up with than the automatic cuts to Medicare triggered if Congress can't sufficiently trim the federal deficit, Jonathan Cohn writes for Kaiser Health News. Those automatic cuts would be relatively modest, experts say.

Health Costs: David Lazarus of the Los Angeles Times explores why a hospital would charge a patient $38,000 for a Crohn's disease drug that only costs the hospital $6,300, even if most of the $38,000 cost is covered by insurance.

Health Insurance: Sarah Kliff of the Washington Post examines why Texas has the highest percentage of uninsured people of any state. Among the reasons: a large immigrant population and the fact that many jobs don't offer health insurance.
