  You know, my mom always told me that (crunching ice drove her crazy) but I figured it was an old wives’ tale. FWIW, my blood work has never shown any deficiency but interesting to know.

    Crunching ice is like fingernails on a blackboard. It bugs the hell out of some of us, others couldn't care less. Fingernails on blackboards have never bothered me. And ironically, I'm hypersensitive to sound.
