When we slather up with sun tan lotion, most of us bypass our lips.  We coat our arms, our legs, our foreheads and noses with a suitable SPF -- but putting lotion on the lips is a non starter. And few people use a separate protective lip balm.  In fact, a recent study out of Baylor University Medical Center at Dallas found that fewer than 25 percent of Americans protect their lips from the sun.

That's a big problem, because our lips are among the most vulnerable places on our bodies -- exceptionally prone to cancers and aging damage.  According to dermatologist Christine Brown, "When skin cancer occurs on the lower lip, it has the potential to be much more aggressive and metastasize to surrounding lymph nodes."

Ever since the feminist revolution, debate has raged about whether it's nature or nurture that determines the behavior of young boys versus girls. Are young boys born with an urge to wheel toy trucks across the floor and crash them into walls, while young girls come equipped with a preference to cuddle Raggedy Anns -- or does socialization create these differences?  Now, a new study by the Yerkes National Primate Research Center in Atlanta, Georgia, may have the nurture (versus nature) advocates a bit rattled.

A new study of 1256 elderly people affirmed that people who have a positive outlook suffer from far less memory loss than their worried peers.  At the initiation of the study, all participants completed surveys about their negative emotions. Then, every year for 12 years, they were assessed for cognitive impairment.  At the conclusion of the study, the subjects who tended to maintain a negative outlook had more memory loss than the more optimistic subjects. In fact, those indicating the highest degree of distress at the outset were 48 percent more likely to develop memory loss than those subjects who were the most positive.
