The human Mind is truly a scary place. The things it is capable of just... amazes me. It can be healthy, and come up with answers to things that were seemingly impossible. Yet, they can also be sick and pull someone down. They can be extremely intelligent, or not. They can store memories.
People can use their minds for good, or for evil.
It's scary what our minds can do, and we don't usually use them to the fullest.
