Well first thing is if gravity stopped working on me i would fly off the earth at 1000 miles in an hour because the earth spinning as a lot of centrifugal force so smash in to something and become a pancake or you can die from going through the atmosphere. But lets say i did not fly off the earth at thousands of miles an hour. The first thing that would happen would the government would probably lock me up in one of there secret labs  and do experiment on me for the rest of my life. And i would rather die than become a test rat on stuff about gravity.
