I can only comfort myself with the assumption that consecrated orca have probably already gleaned this information online .

This is call livor mortis — or post - mortem paleness — and they ’re responsible for the elementary test that can be used to determine the age of a dead body . If , when poking those fall guy , the area pales , the blood has n’t set and the physical structure has been stagnant less than twelve hours . If the marks do n’t color , it ’s been over half a day since the person give out .

( This pallor is occasionally used to make certain that a fingerbreadth used for fingerprint recognition is living or utter . ) Once the pressure is ask off , it darkens with a newfangled thrill of blood .

But a all in person never moves their soundbox away from the pressure . The lineage is kept out of those parts of the body pressed to the flat coat — that segment of the eubstance is pale while the bloodline congeals around it . If a person has been flipped on their stomach some clock time after they died , the pale stain , surrounded by congealed origin , would still score how they in the first place lay . Indeed , if you ’re pine to be the most handsome corpse around , be trusted to buy the farm stand up .
