In each stair climb the ladder a person consumes and weighed about 70 kilograms, 1 and 0 great price. If stepped up ten stairs, you are consumed during that one great price, equivalent to 1/4 gram of blood sugar. And you feel for it as you go up 40 stairs when your body consumes during which 1 gram of sugar. The body burned sugar by taking oxygen from the air, and the heat energy generated in the body the body converts it into energy movement (boarding). When stepping find that you breathe deeply to take greater oxygen from the air.

Climb 40 stairs equivalent to taking the body to a distance of 8 meters higher; and consumes the body through which 1 gram of sugar. This high efficiency of the body in converting thermal energy into kinetic energy. For example, if you want to lift a load of 70 kg a distance of 8 meters by machine steam you need a large amount of coal or wood so that heats water, it produces steam, and the steam to run the crane. This is because the heat generated from the combustion of coal or wood mostly dispersed into the atmosphere, and take advantage of a small portion of them to run the steam engine crane. The body's efficiency in converting heat energy into energy much greater than the efficiency of the steam machine movement.
