The example of Lagann: out of this world (Tengen Toppa Gurren Lagann) (№ 30476)

You know why people's eyes in the front? When you see your target, much easier to go forward than to back away.. If the eyes were at the back, you would have seen all that is left behind. And it would hurt you to go forward. And with eyes front do you see as your goal is becoming closer. And it helps people to move forward.
But there's something else. Eyes in front allow you to see those who have gone before you.
