GagReflexFilter....I don't know if I can adequately explain this medical problem, but I'll try...(It's one of those things that if it doesn't happen in the doctor's office, they don't know what you're talking about.) [more inside]

So I'm still trying to pinpoint this one (I keep forgetting to ask it, and Google turns up nothing)-- when one lies down in a bathtub, faceup, and submerges at least their entire ears, they shiver (it's more kind of an uncontrollable, brief spasm of the upper body and doesn't FEEL like shivering, but looks like it). It isn't related to the water temperature, as far as I can tell, and DOESN'T happen when facedown or swimming, etc. Or do other people not have this happen? Do you? I get it every single time, without fail, and have since I can remember. My mom knows exactly what I'm talking about, but my dad insists we're both crazy. Is this just one of those odd reflex reactions like coughing when you have something in your ear or sneezing when you get in the sun? (I also do that one-- always funny to explain to people :) ) Any idea what causes this, though?
