野马深知一个道理：在竞争残酷的环境中，多一份警惕，就多一份生存的希望；多一份松懈，就会向死亡迈进一步。

生活在复杂的自然环境中的动物，都有特定的睡觉姿势，这是它们在弱肉强食的生存竞争中形成的睡眠习惯。野马是生活在草原上的食草动物，在生物链中，它们成了食肉动物的攻击对象，随时都有被吃掉的危险。因此，不管是白天还是晚上，它们睡觉从不躺下，而是保持着站立的姿势，闭上眼睛睡觉。一旦有猛兽袭击，这种睡姿可以让它们随时警戒，防御敌害，同时还可以迅速逃跑。即使是在长途奔波以后，它们也只是站在树阴下低头闭眼可以打“瞌睡”；在确定没有危险的地方，它们也是把头搭在彼此的背上睡觉。

Mustang know a truth: in the brutal competition environment, more alert, more of a hope of survival; a slack, will further step to death.

Life in the complex environment of animals, there are certain sleeping posture, which is in the law of the jungle survival competition they formed in sleep habits. Horses that live in the grasslands of herbivores, in the biological chain, they become vulnerable to predators, are ready to be eaten. Therefore, whether it is day or night, they never lie down to sleep, but maintained a standing position, close your eyes and go to sleep. When the beast attacks, this position can let them always alert, defense against predators, but also can quickly escape. Even in the long run, they just stand in the shade with eyes closed you can play the " sleepy" bow; in determining no dangerous places, they are also head rested on each other's backs.
