Oprah and Skype have joined together to start this incredible new campaign! Just Say Hello encourages everyone to say “hello” to people. Simple as that. It can be to a stranger, a person who looks down, a long lost friend, or someone in need. Research has proven that social interaction can help us all to live healthier, happier, and longer lives. With one short word, we can all help fight loneliness and vastly improve the lives of everyone around us!
