I know, Irene! It is so funny; the brain is a machine who is working to understand itself.

There is an urban legend that sais humans only use 10 % of their brain. I do not think it as simple as it sounds, because most of what happens in the brain is subconscious. If the amount of process we are conscious becomes bigger, I'm not sure if it activates the brain more, but it sure feels like it. With awareness, we can already do awesome things

Well, you know, when I have to think about lots of things, I feel overwhelmed and I get splitting headache. So maybe it would have been cool to have awareness of more brain functions, but maybe it's not just a random event that most of our thought process is done on subconscious level.

Indeed, it would be quite disturbing to be aware of every little colour diffrence in a room or every step that happens between pushing a button and lights going out.

There is a guy called Bob Proctor, who states that subconscious can be changed. https://www.youtube.com/watch?v=-vngnTStQvY
