My book is about the brain, which is the first and last engine of our bodies. I consider that the brain exists in three main parts, namely: the (Heart-Intestines-Head) And it is connected by a hormonal links and electromagnetic waves, and it forms a group that controls all vital processes, not just thinking, rather feelings, immunity, and even control the survival of the cell in its activity, or it dies and the life of the cell ends. There are factors that help in functioning efficiently. Therefore, we must focus and follow up on the children of determination through the activity of their brains. The factors that I mentioned in my book are important to help us develop and modify the brains of our children of determination.
