It's nice when you are with someone and you find that small nooked haven just beneath their neck. And to lay your head on their warm muscle is very comforting. I don't know why such a spot makes an individual feel so at rest, however a sense of intimacy is created from that nook, and I suppose as you hear their heart beat, and feel their chest move up and down, a reassurance washes over you. Knowing that the are definately alive! In all seriousness though. It is very special.
