Were Reeva and Oscar really in love? Openly they professed unconditional love, but a close member of her family, in an interview on an American TV Channel said: "Reeva did not love Oscar." Later he added: "the less I say the better." Was he telling the truth? We will never know for certain. Adults rarely say what they really think. Usually they say what they like, depending on the situation. Only little children speak the truth because their brains are not yet fully developed. They have no memories to compare with given "live" situations. They cannot see lying as beneficial for them, until they start experiencing and accumulating this knowledge in their innate. Many people wonder why Oscar killed Reeva. In this book I try to give an answer to this question based on physiology and the functioning of the human brain. But this may be only one of the possible explanations as we live in a world we don't yet fully understand. That is why I also pose several questions concerning the Theory of Relativity, which for me is as equally enigmatic as the functioning of the human brain. Although a part of the Universe, we live in a world created by our own brains, each one of us in a unique time frame. These time frames move against one another at different speeds and directions, back and forth. Reality, it seems, is not what we perceive, but what our brains build, based on strings of information received from a variety of sources, external, i.e. from outside of our bodies and internal, from the inside. Often this existence becomes upset by environmental factors coming our way or due to our own actions. These factors and actions throw our well organized lives out of balance for long periods of time, sometimes even permanently. In Oscar's life this happened on the early morning of Valentine's Day 2013.
