Why should you keep a snakebite below your heart?

Answer 1

Assuming you mean a confirmed bite from a venomous species... You keep the bite area lower than the heart - because it slows the circulation of the injected venom through the victims blood stream. You can also apply a pressure bandage (NEVER use a tourniquet !) to the bite wound, which will also delay the venoms path through the victim's circulatory system.
