A:
No, the human body is definitely not a superconductor.   A superconductor is a material that looses all resistance below a certain critical temperature.   I assure you that at all temperatures the human body has a finite resistance.     The actual value depends upon many different parameters: wetness of the skin, length of travel through the body, etc.  If you  take an ordinary Ohm-meter and grasp the leads you will find values ranging from a few kiloOhms to megaOhms.
