It also changes through- out our lifetime as does the weight we attribute to it in our preferential judgment. I remember that as a child I had two very close friends that were sisters. While in the view of many others they were not physically attractive, in my mind they were the most beautiful people I knew. This is because of their sincere care and affection. On the other hand, I had a very close family member that was only centered within her very own issues. Every few years she would perform a different type of plastic surgery, but no matter what the result was, I still never thought of her as a nice or pretty person. In one of the bible books, the book of Kohelet (Ecclesiastes), which is a type of personal biography, the author says: “hevel hachen vesheker hayofi ” meaning (from the Hebrew): charm is deceptive and beauty is vain. In essence, physical appearance may be misleading and illusory. Personally, I know that in time perspective, the way I remember people is not by their appearance, nor by their words, or what they have given or taken from me. In essence, I think and remember them by the way they made me feel. In one of the books I read, I came across an interesting differentiation between public and medical journalism. While the daily public news wishes to bring the shocking, devastating news, medical journals will only rarely publish “bad” unexpected data. If a study failed to prove a hypothesis it will most likely not be published. In this sense, this book is staged beyond pure science–it provides cautious optimism combined with reality. The protestant theologist Reinhold Niebuhr is communicating to God asking him the following: “grant me the courage to change the things I can change, the serenity to accept the things I cannot change and the wisdom to know the difference.” xv xvi Preface I am hoping that this book will provide the reader with a few tools to understand what can or cannot be changed in the process of skin aging and therefore will ease the acceptance of the unchangeable and encourage the further exploring of the processes that may be controlled. In our society there are great social advantages to being attractive. Common stereotypes of elderly people depict them as physically unattrac- tive and sexually undesirable (Koblenzer, 1996).
