This first two-to-three-hour period after death is known as primary relaxation. “Just relax, babe, no worries. You’re dead.” Even if you happened to be making a silly face when you died, face muscles relax along with everything else during primary relaxation. Your jaw and eyelids will fall open and your joints will get all floppy (“floppy” being the medical term). Say goodbye to your wacky face.
