...increasing body of evidence has suggested that participating in mentally stimulating activity, socializing frequently and exercising may help protect against age-related decline - at least cognitive decline. As early as 1995, neuroscientist Carl Cotman, who studies aging and dementia at the University of California at Irvine, published a paper in Nature showing that physical exercise produces a protein that helps keep neurons from dying and spurs the formation of new neural connections in the brain. More recently, Cotman demonstrated in studies of elderly dogs and mice that enriching their social environment is associated with improvement in brain function...
...activity may be linked to the same protective effect in people. A recent study of 2,500 adults ages 70 to 79, published in the journal Neurology, found that those who were able to stay mentally sharp were also those who exercised once a week or more, had at least a ninth-grade literacy level and were socially active.

...symptom of physical decline, since people may naturally withdraw from social engagement as they lose motor skills - most researchers would agree that it is not unreasonable to encourage seniors to get out there more. Only 10% of people over 65 get the recommended amount of exercise (at least 2.5 to 5 hours a week), and given that seniors already tend to be more socially isolated than younger adults, it's difficult to motivate them to become more active. "If you are alone, you are less likely to follow recommendations," notes Verghese. It might help, though, if you visit with Grandma...
Moms might want to hang on to those Mother's Day cards they got last month. There may not be much more familial goodwill forthcoming - at least not after kids get wind of a new study released by Harvard-affiliated McLean Hospital and published in the online journal PloS One. Turns out that your mother's feelings for you may not be the unconditional things you always assumed. It's possible, researchers say, that the prettier you were when you were born, the more she loved...
...never been a secret that beautiful people get more breaks than everyone else, nor that the bias may start in the nursery. An oft cited - and deeply disturbing - Israeli study once showed that 70% of abused or abandoned children had at least one apparent flaw in their appearance, which otherwise had no impact on their health or educability. McLean psychiatrist Dr. Igor Elman and postdoctoral student Rinah Yamamoto devised a study to explore that phenomenon more closely. (See pictures of pregnant-belly...
