Some people like to live on the edge. And sometimes the edge ... slides.
Many people seek gratification by challenging the limits of the laws of physics with their personal determination, strength and ingenuity. The laws of physics remain a constant. Gravity, mass, potential energy, and kinetic energy, temperature mediated molecular motion, wind, precipitation etc. Its the human ingenuity that often fails. Yet as long as mankind exists, those limits will be challenged, sometime resultng in wondrous things.
