In the pupillary light reflex, shining a light in the eye causes nerve signals to go from the eye to the brain and then back the eye again, telling the pupil to constrict. In the usual sneeze reflex, tickling the nose causes nerve signals to go from the nose to the brain and then back out to the nose, mouth, chest muscles and everything else involved in the actual sneeze. The key point is that the nerve signals take complicated routes through the brain, but usually the pupillary light reflex and sneeze reflex take different routes. Apparently what happens in sun-sneezers is that shining a bright enough light in the eye ALSO sends nerves signals from the eye to the brain and then back out to the nose, mouth and chest! In short, the wires are crossed a little bit in some people, and so shining a light in the eye "accidentally" activates two different outgoing pathways.

Googled it and got this.:thumbup:

 

Dean's not a coward, but neither is he a fool. He knows what he can do, and what he can't. He's put his life and soul on the line facing down the angels, and all this without powers. Sam, in his own mind, has less to lose, because he has a weapon that Dean doesn't have, which, as I said, gives him a feeling of superiority. I have to wonder why Sam seems to actually gloat in his ability to do what Dean can't.

 

Who is Sam dean?
