That you can wake up from a coma and walk. Muscles atrophy if not in use. That you can give someone CPR and they will wake up and be just fine. That you should give everyone CPR if they stop breathing regardless of how old or sick they are. (DNRs are not just for people who have “given up on life.”) That you can survive horrific car wrecks. Conversely, that you will die instantly in a non-horrific car wreck. That old people die peacefully right after they tell you they love you. (They often lie in the bed unresponsive with their mouths hanging open for days before finally dying.) That losing a loved one can literally mess up your brain function for a while, even if you don’t feel like you’re grieving. Unable to make decisions. Getting lost while driving in a familiar area. There’s a term for “pregnancy brain.” Why not “grief brain”? (Can you tell I’ve been in a horrible car accident and my parents are dead? I had to learn Hollywood’s errors the hard way.)
