Getting a good grip on your health may mean … getting a good grip. The force you can muster when squeezing an object or a weight doesn't only reveal how strong your hand and arm are. It can be a measure of overall muscle function and — according to one recent study — even portend how long you're likely to live. That's not as nutty as it seems, says Richard Bohannon, a professor of physical therapy at the University of Connecticut. "Grip strength reflects your overall muscle status and a general sense of how much muscle mass you have" he says.

By quizzing small children about the first events they remember — a cousin misbehaving, a trip to a grocery store, a mother's bribe of red and green licorice — researchers have discovered that the earliest memories of children shift as they get older, and don't solidify into the first memories carried throughout life until about age 10. The research, published Wednesday in the journal Child Development, could help psychologists better understand...

Want to live to 100? A new study suggests that, for men, your testicles might be holding you back. Korean eunuchs - men who had their testicles removed - outlived their contemporaries by as many as 14 to 19 years, suggesting that male sex hormones somehow act to shorten the male human lifespan, according to a new historical study of records spanning from the 14th century through the early 19th century. The finding, reported Monday in the journal Current Biology, argues for something called the "disposable soma theory.” The idea is that since animals have limited access to energy, there is a natural trade-off between reproduction and the maintenance of the body's cells.

People who are socially isolated are more likely to die prematurely, regardless of their underlying health issues, according to a study of the elderly British population. The findings, published online Monday in the Proceedings of the National Academy of Sciences, showed that when mental and physical health conditions were factored out, the lack of social contact continued to lead to early death among 6,500 men and women tracked over a seven-year period. "They're dying of the usual causes, but isolation has a strong influence," said study author Andrew Steptoe, an epidemiologist at University College London.

Two recent studies linking childhood television viewing to antisocial behavior and criminal acts as adults are prompting some pediatricians to call for a national boob tube intervention. A commentary published alongside the studies in the journal Pediatrics on Monday lamented the fact that most parents have failed to limit their children's television viewing to no more than one or two hours a day -- a recommendation made by the American Academy of Pediatrics. On average, preschool-age children in the United States spend 4.4 hours per day in front of the television, either at home or in daycare.

For a majority of U.S. teenagers, "homework" is finally living up to its name. Thanks to the Internet, research projects and other school assignments are being completed at home, online, replacing last-minute trips to the library, according to a study released Saturday.
