Blood is what gives every part of the body nutrients to keep healthy and working properly, but like any river system, it gets dirty and full of garbage.  Dead blood is exactly that, and creates blockage in the blood system, turning veins into varicose veins that are unsightly.  Slapping is the quickest and most effective methodology to getting rid of dead blood.  The area where you don't have dead blood will just turn pink and go back to being normal shortly, but if it does have dead blood, then that area will turn from deep pink to purple to even black.  This gets rid of any pain, stiffness, lack of range of motion, and many other discomforts you may experience.  It rejuvenates the skin like a miracle.​
