Go to the Big Pointy Building (the one with a parachute) in the Downtown area and jump off. Open your parachute and land. Go back up to the top. This time, you will not get a parachute. Jump off. Before you hit the ground, you will hit the side of the building and slide down. When you are close to the ground, you should hit one of the many slanted poles that hold up the building. This will slow you down enough so that you only lose about one sixth of your health. Sometimes you will not hit a slanted pole and lose more health or die.
