The 'WHY' handbook presents and evidences that human decisions and actions are most strongly determined by our underlying basic inborn human nature and survival instincts. The uniqueness of 'WHY' is in bringing to light certain truths that are often covered-up, hidden and de-emphasized because they oppose norms, rules and laws of society which leads to our unwillingness to concede, admit or accept these 'inappropriate' or questionable behaviors the 'WHY' thesis]. The 'WHY' handbook tries to unequivocally evidence this truth and in so doing increase our knowledge and understanding of humans in a way that will make all of us, especially the younger and less exposed reader, more secure, safe, accepting, appreciative, comfortable and supportive of the exceptional human race in all of its unmatched aspects, abilities and qualities.
