a little bit of my point of view of the feeling ...

To feel is to wake up in the morning in silence, look at your hands, smell them, touch them together, stop to touch the face, the eyes, the nose, the eyelashes. Go down the neck and shoulders giving us a little hug. go to the arms touch the breasts and the waist, touch the thighs and the legs and the feet. 

To feel alive is to feel you, because you are alive and there is nothing more full of joy than you.
