You know what else is weird about me, besides the obvious? Coughing makes me sneeze. If I start coughing & can't stop, I will sneeze!! I will also sneeze if I'm laying out in the sun. Reflexive sneezing induced by light, and sunlight in particular, is estimated to occur in 18 to 35 percent of the population and is known as the PSR (photic sneeze reflex) or the ACHOO (autosomal dominant compulsive helio-ophthalmic outbursts of sneezing) syndrome.
