jus' flingin' in my two cents' worth:

I don't sneeze in bright lights (well, sometimes I do, but not because of the bright lights! ie, not because I've moved from somewhere dark to somewhere light). The first I heard of this phenomenon, someone I knew told me her doctor had said something to her about, "You know how you sneeze when you first go outside on a sunny day?..." I said, "You do?" and I think she was surprised by this as well - we fell into the "are you crazy?" school and he was obviously one of the "doesn't everybody?" school.

Interesting how an individual's view of what is universally true/real often develops from individual experience without reference to what is true/real for others....

If you can't see the bright side, polish the dull side.
