Yawning and it being contagious

  1. Aug 28, 2003 #1
    This may not be the spot but I figured after I put it somewhere it would be moved to where it needs to be.

    I have question about yawning and it being contagious (sp?)Why are they contagious? Is it a mental thing? Someone at work asked me and I thought I would come here and ask the experts!
