Skeptics are those guys who rely only on scientific evidence in order to know if something is true or not. I say that they are the gatekeepers of scientific truth, because many things that sound scient-ish and are sold as absolute truths, are in fact, actions of con mans or simply misguided befiels.
Did you hear about the anti-vaccine movement? Well, this movement kills children because people believe that vaccines are bad and they credit the fact that some diseases have disappeared due to the fact that we clean our bodies more now. That is also true, being clean does help, however vaccines help even more.
See what a vaccine is in the video from below starting at minute 3:00.
So, if you find a skeptic somewhere, take him home. He might save your life!
