This should make you even more aware of how remarkable the human body is, that each of those teeth has a particular place to be, and they mostly end up in the proper place. (Yes, all living things are remarkable.)

    This isn't quite accurate. Yes, it can happen, but it's pretty rare, it happens when there's a hole in the membranes around your brain or spinal cord, not just to reduce brain pressure, there's usually other symptoms associated with it, and if it does happen, you should see a doctor. It can heal on its own, but it also puts you at a risk for meningitis.

    Eat it fresh out?! That's a bit much. I mean other mammals do it but I can't wrap my brain around a human doing that. Haven't looked this up recently, but I've heard of drying it out and putting into a pill form and just taking it like a daily vitamin. Edit: if you've eaten a fresh placenta, no shade to you. You do you. Not trying to offend anyone.
