Why is blue shift not called violet shift? I never got the reason, I realize it's possible that there is no reason other then it's easier to say, but I would love a solid answer. Red and violet are at opposite ends of the visible light spectrum, it would make sense to call it violet shift instead of blue shift. Now here's where you make me feel like an idiot because I'm worrying about such a trivial thing.

I get something similar, I have to have laundry detergent around me so I can smell it or just be comforted by it. It's weird, and strange. But yours sounds like something that could hurt you. Most likely, a deficiency of some sort. *shrug* I dunno, just a guess, I'm no expert. For all I know, it could be menopause or a mid-life crisis. iNow, brain tumors would cause personality changes. This is a sudden craving. And it's not rational to assume the worst before eliminating the most common reasons. Pica, huh...? So you have a craving to eat objects that you shouldn't eat? I had that slighty for a short while when I had iron deficiency. That could cause it, as well as a tapeworm. It's best to assume the most common things before you start freaking out about a brain tumor that you most likely don't have. See a doctor, if it's a tapeworm or a deficiency, then it needs to be taken care of. If it's psychological, then see a psychologist. Point is, you most likely will not get a diagnosis without flaws on the internet, especially if it's an amature diagnosis. See a doctor. Like ASAP.
