Well I read somewhere saying that it's the brain that's giving out signals to human beings, including feelings and love. But why, why is there this weird feeling coming from the chest area, coming from the heart? Isn't the heart just a block of muscles that pump blood to the body. Why is this feeling coming out from it? What's worse is that the person don't even know what that feeling exactly is. Is it happiness, sadness, frustration, warmth?
