One of the many security problems with humans is the time when their body sleeps (rest). Humans spend a lot of time of their lives sleeping (1/3 approximately). But not only that, the human body get sleepy every day (before the sleeping process), and because of that, the body is increasingly working improperly; and after, when the body finally wakes up, is necessary some time to make the body work again properly.
We desire to be always awake (without the need of sleeping), that requires important modifications in the human realm, and we don't know how to do them yet.
