Time to Stop Biting Those Nails: The American Psychiatric Association is labeling compulsive nail biting as an obsessive compulsive disorder, or OCD. Only extreme nail-biters will fit into this category – those who bite their nails so much that they have gotten infections, or otherwise impaired the use of their hands. Even if you only occasionally bite, beware: doctors say any biting can increase the risk of skin infection or even a cold, due to the spread of germs from hand to mouth. Women’s Health magazine has compiled a list of the best ways to kick the habit – check it out here.


Don’t Drink and Drive: A new report from the Centers for Disease Control explains that the number of teenagers who drink and drive has been cut in half over the past two decades. That seems great, until you realize that there were still one million teenagers who reported drinking and driving in 2011 – and that’s just the ones who will admit to it. Compared to older drivers, young drivers are 17 times more likely to die in an alcohol-related accident. The report shows that teenage boys are more likely to get behind the wheel drunk than girls, and Caucasian and Hispanic teens are more likely than African Americans. It is a good sign that the numbers of teenagers drinking and driving has decreased, but it seems like we still have a long way to go before stopping it altogether.


Stop the Supplements: It is commonly reported that vitamin D deficiencies are linked with heart disease, bone fractures, depression, and a compromised immune system, but it appears that taking high doses of the vitamin won’t actually help you. A study in New Zealand proved that adults taking large monthly doses of vitamin D supplements were just as likely to suffer from an infection as adults taking a placebo. This study disproves similar studies performed in the past, even as recently as this August. A doctor involved in the study concluded that colds are inevitable, despite supposed remedies.
