Exercise has had a Goldilocks problem, with experts debating just how much exercise is too little, too much or just the right amount to improve health and longevity. Two new, impressively large-scale, studies provide some clarity, suggesting that the ideal dose of exercise for a long life is a bit more than many of us currently believe we should get, but less than many of us might expect. The studies also found that prolonged or intense exercise is unlikely to be harmful and could add years to people’s lives. No one doubts, of course, that any amount of exercise is better than none. But unlike medicine, exercise does not come with dosing instructions. But whether that amount of exercise represents the least amount that someone should do — the minimum recommended dose — or the ideal amount has not been certain.

High-Sugar Diet Can Impair Learning And Memory By Altering Gut Bacteria. The typical American diet is loaded with fat and sugar, and it may be hurting not only our physical health, but also our ability to think clearly.

High-Sugar Diet Can Impair Learning And Memory By Altering Gut Bacteria

New research from Oregon State University finds a high-sugar, high-fat diet causes changes in gut bacteria that seem to lead to significant losses in cognitive flexibility, a measurement of the brain's ability to switch between thinking about one concept to another, and to adapt to changes in the environment. The study, which was conducted on mice and published this week in the journal Neuroscience, found that a high-sugar diet was particularly detrimental to brain function, leading not only to decreased cognitive flexibility but also to impairments in short- and long-term memory. “We’ve known for a while that too much fat and sugar are not good for you,” Dr. Kathy Magnusson, a biomedical scientist at the university and the study's lead author, said in a statement.

As Magnusson suggests, the findings aren't entirely surprising. The world's most advanced Prosthetic Hand - bebionic. Study: IUD use effective for pregnancy prevention.

You’ve probably heard that marriage among young adults has been on the decline, but a new Gallup poll finds that the percentage of 18-to-29-year-olds living with a partner has flatlined in recent years.

Marriage?? Young Americans Aren't Even Shacking Up

“This means that not only are fewer young adults married, but also that fewer are in committed relationships,” Gallup’s Lydia Saad wrote Monday. “As a result, the percentage of young adults who report being single and not living with someone has risen dramatically in the past decade.” Related: The Bad News About All the Singles in America That percentage has risen from 52 percent in 2004 to 64 percent last year, Gallup says.

Fifty hospitals in the United States are charging uninsured consumers more than 10 times the actual cost of patient care, according to research published Monday. All but one of the facilities are owned by for-profit entities and the largest number of hospitals — 20 — are in Florida. For the most part, researchers said, the hospitals with the highest markups are not in pricey neighborhoods or big cities, where the market might explain the higher prices.

Topping the list is North Okaloosa Medical Center, a 110-bed facility in the Florida Panhandle about an hour outside of Pensacola. Uninsured patients are charged 12.6 times the actual cost of patient care. Community Health Systems operates 25 of the hospitals on the list. 40 years of a changing American diet, in one massive chart. You don't eat the way your parents did.
