Usage/Power of Boolean

Title of this post is strange to others. When I say power of Boolean, it does not mean any mathematical term, but to some extent it is. Actually, every-thing is based upon bool type.

Our daily life is also using this type. Every person or majority of people use bool efficiently. I am not talking about their end result/product. I am talking about usage of bool type.

What do you think about this type?
Do you have any other thought for this type?

Just answer my questions in comment area.
