Safety E books from Peter Ribbe have been formulated to teach individuals about safety and when and how to use it. Safety is a state of being danger less and in an environment of any harmlessness. These books tell us how too much safety affects us. For example if a mother is determined to keep her child from all pain, the result is a danger as there is more harm and less happiness. Avoiding germs gives you a weak immune system, important safety standards may cost lives etc.
The book pens down examples of risking life and explains why we should risk our lives sometimes. When people indulge in adventure sports, they often know the associated dangers and risks, but still they go on. Life is short and full of risks. So risk and enjoy life while you can.
