Last Saturday I was in the hospital with a deep pain in my neck. When I was there, an old man arrived, lying in a stretcher and he stayed in front of me for some minutes. It pointed his feet out to me for his straight with curves lines. Not only the feet, but also the hand and fingers of that work man who I observed. Following the Leonardo da Vinci's advise, I was with my little sketch book in the T-shirt pocket, and could catch some lines of these shapes that really amazed me.
