#JUSTSAYHELLO There is a new campaign out there called Just Say Hello! There is research that suggests that as we become more "connected" virtually, we actually become more distant and lonely. Scientists have proven that loneliness hurts! Loneliness lights up the same parts of the brain as physical pain therefore we process loneliness just like we do a scratch or a cut. (http://www.livescience.com/18800-loneliness-health-problems.html) Dr. Sanjay Gupta is challenging people to #justsayhello! To a stranger or to a friend! Not virtually but face-to-face! When you pass them in the hallway or you pass them in your neighborhood, make eye contact and just say hello. You will make others feel better and yourself feel better which addresses loneliness for the both of you!
