Introducing the positivity-enhanced HAPIfork! It is an electronic fork that monitors your personal eating style and habits and gives you cues as to when you are eating too fast. The HAPIform will alert you with lights and vibrations when you are shoveling food into your piehole.

Electricity travels through conductors - any material which allows electrical flow - as it tries to reach the ground. Because people make excellent conductors, minor electrocution is a common household hazard. Fortunately it is usually more surprising than dangerous and does not require medical attention. However, some basic precautions should be taken to insure that the shock does not interfere with the body's normal electrical impulses including the functions of the brain and the heart. Prolonged exposure to a direct source of electricity can also cause severe burns to the skin and the tissue.
It would work faster than a $100.00 vibrating fork.
