Weight is a good guideline for blood volume in people of average build. This is why we set a minimum weight limit of 7st 12lbs (50 kg) because if more than 13% of blood volume is taken there is more risk of the donor feeling faint after donating.
Not surprisingly, the one factlet most often offered up as revealed truth is wholly false: Your hair and nails do not continue to grow after you die; it's all optical illusion. The sorry fact of the matter is that we dehydrate after dying. Our flesh dries and, in so doing, pulls away from nails and hair.
Between 20 to 50 days after death, the body begins to dry out as all of the remaining flesh is consumed by insects. Maggots can no longer feed on the dry body because they canât chew through the tough tissue.This is where the beetles take over.They can chew through the remaining tendons and ligaments, until all that is left is bone and hair. Between 50 to 365 days after death, moths and bacteria consume the hair.All that is left is bone; it can last indefinitely as long as there are no predators around. This whole process can be hastened or slowed depending upon what happens to the body after death.he skin takes on a cottage cheese like appearance. This happens between 4 and 10 days after death. The liquid leaks out into the soil and attracts even more insects. A body can fell warm to the touch at this point due to all of the insect activity.
