...leading theory to explain this fortunate disconnect is the brain-reserve hypothesis, which suggests that people who have more cognitive ability and more neural tissue to start with - sharper minds, broadly - may be better able to withstand the ravages of age. "In some ways, you could think of it like a trained athlete who might be able to resist some atherosclerosis of the heart," explains Dr. Bradley Hyman, director of the Massachusetts Alzheimer's Disease Research Center and a professor of neurology at Harvard Medical School...
...narrative was whether she could possibly juggle her complex personal and public lives. By now we're used to seeing stories about professional women who conclude that "having it all" is a myth and leave the arena in search of their inner Donna Reed. This "trend" is used to explain the paradox that women now make up a majority of college grads and have roughly matched men in law and business and medical schools but are still paid less and remain dramatically underrepresented in executive suites, not to mention statehouses and the White House.

Now that's beginning to change. At Carnegie Mellon, for instance, psychologist Sheldon Cohen has been exploring exactly how positive emotions affect the body. (This is the flip side of previous work by Cohen and others linking stress, Type-A behavior and negative emotions to lowered immunity, heart disease and shorter lifespan.)

With or without physicians' support, the idea may be creeping forward. Last week, De Brantes was part of a group of health-payment reformers invited to the White House to explain how bundling works. Meanwhile, the federal Centers for Medicare & Medicaid Services recently started a three-year demonstration project that will provide bundled payments to hospitals and doctors at five sites for 37 common surgical procedures. The idea is that if hospitals and doctors are paid out of the same pot, they'll coordinate services to be more efficient and cost-effective. The results could help determine how aggressively...
