The ultimate leap is built on a cliff, built on the height of the cliff. Jumping on a pedal that is 30 cm or even wider can be a shackle that doesn't look so easy. The small heart squats all the way. If you accidentally jump, you may step on the air, but the insurance work is in place. Extreme sports are conquering yourself. When you overcome these difficulties and bravely take that step, you have already won. All extreme sports are not allowed to experience if you have a fear of heights or heart disease.
