Which is your kryptonite- noise or light? My kryptonite is bright light. I have very light colored eyes and bright light is something I shun. If light is too bright I feel possessed. I am also likely to get a bad migraine. While I don' t especially like very loud noise, the drone of daily noise does not bother me. I find it comforting to listen to normal noises in the apartment building I live in. It makes me feel less alone.
