waaw, I feel something here. This post taught me about strength, as if I enjoy learning science. ranging from the brain, eyes, how to regulate breathing, conscience, stomach to digestion, this is an important force in life. Well, what if one of them gets into trouble ?, surely this will be a big problem. then a clever man is every soul who is able to maintain every development of power. The brain is the way out for any idea, be it a good or evil idea, and if one of the other body power systems is disturbed, surely this will lead to the brain, then the strength in the body needs care. maybe this comment is far from the post intent above, but that's the picture of my mind.
