There continues to be a belief among many people including some healthcare workers that after death, the fingernails, and hair grow. In fact, this has even been stated in many older medical textbooks. But is this true? Can your nails and hair continue to grow after your heart has stopped beating and you have no signs of life?
Well, when a person is dying and during the very final moments of life, the skin starts to dry out and shrinks. If you closely observe people during the last moments of death, you will note that the skin will start to become smoother and the facial wrinkles will also disappear. As the tissues underneath the skin start to dry out, the hair on the skin starts to become more obvious and appears longer. The same thing happens on the fingernails. The skin starts to retract or shrink and the nail starts to appear longer. This is an illusion that the nails and hair are growing, when in fact the skin and tissues underneath have retracted.
Another similar illusion where the body part appears longer than it really is occurs during penile lengthening. Many men feel that their penis is short and go to great lengths to elongate it. The penis is attached at its base to the pubic mound. In most people the pubic mound has a moderate amount of fat. In fact in some people the pubic mound can be so big that the penis is often buried inside. Hence, some surgeons elongate the penis by removing the fat and other tissues from the pubic mound- so it appears that the penis has increased in size. In fact, only the fat from pubic mound has been removed- again it creates an illusion of a longer penis.
In reality this is not a procedure that is recommended because if the surgeon accidentally cuts some the ligaments that hold the penis to the base of the pubis, you will forever have a limp penis.
