Research by Kurt Gray, a doctoral student in psychology at Harvard, shows that a person's capacity for willpower and physical endurance increases if they perceive themselves as good or evil. "Evil" acts in particular give a person a large boost in physical strength. From the article: “'People perceive those who do good and evil to have more efficacy, more willpower, and less sensitivity to discomfort,' Gray said. 'By perceiving themselves as good or evil, people embody these perceptions, actually becoming more capable of physical endurance.' Gray’s findings run counter to the notion that only those blessed with heightened willpower or self-control are capable of heroism, suggesting instead that simply attempting heroic deeds can confer personal power."

It's one of the fastest-growing health issues that doctors now face: "Google-itis." Everyone from concerned mothers to businessmen on their lunch break are typing in symptoms and coming up with rare diseases or just plain wrong information. Many doctors are bringing computers into examination rooms now so they can search along with patients to alleviate their fears. "I'm not looking for a relationship where the patient accepts my word as the gospel truth," says Dr. James Valek. "I just feel the Internet brings so much misinformation to the (exam) room that we have to fight through all that before we can get to the problem at hand."
