Normally, cow, goat, and buffalo animals have four legs on the ground and sit back and relax. Elephants and camel-like beasts are sitting on the ground as well. By so doing, they give their legs relaxed. But the horse is not visible. It's a fastest animal. With the speed of running several kilometers away, tireless power has its own. The reason is that the muscles in its legs are strong and strong. The horse is capable of changing the body, changing one after the other, on the three legs. So it does not need to keep his legs folded like the rest of the animals. It can also stand up and sleep. Once upon a time, the floor is fully resting on the floor.
