Argus of the Greeks was said to have plenty of eyes, he too. Here's the story. His surname derives from the hundred eyes in his head or all over his body. After Argus was slain, his eyes were transferred by Hera to the tail of the peacock. Even if you see a lot, like the guarding Argus, it's possible to fall asleep from it.

Defence mechanisms take deeper sanity for the sake of appearances on the surface levels - they don't give it. And that's the big problem. The finest hero is seldom found The tallest hero sees a lot more than others.
