I am not a medical doctor man.
I have no advanced degrees in understanding how to prevent the very gross human body from spontaneously combusting or collapsing into a heap of phalanges, ears, and intestine. If you need some kind of basic medical care, you are generally better off consulting a box of Ritz crackers than asking me to fix whatever boo boos you might've just incurred.
But despite my general lack of medical knowledge, I do know that your brain is fairly important. It is not usually advised, for example, to allow it to slosh violently against the sides of your skull like toilet bowl water in an RV bathroom.
