The sun with all its spectrum of cosmic rays is the source of life on our earth. As any pagan god or mythical superpower, the ancients worshipped, loved and feared sun. After thousands of years of human race development, we still worship, love and fear the sun. The knowledge accumulated over these centuries guide us to the rules of dealing with this mighty power. Through this presentation, we will revise together the important knowledge about the sun rays and their interaction with our skin. We will revise together the rules that govern our life under the sun; rules of sun exposure and of sun protection. Sun exposure is not all good and not all bad and so is the use of sun screens. The value of sun screens will, also, be discussed to clear facts and myths about them.
