No kind of light makes me sneeze. If I get hit in the nose, though, it's on! I love to hear people sneeze; I will laugh until my shirt is totally wet with tears!I have no idea why I get so tickled. I read a page where people were talking about what made them sneeze, and it was all I could do to get through it. And, mrd, there was somebody who sneezed when they ate chocolate. If anyone wants to read this page, PM me with your email address and I'll send it to you.
