We now know: the human body is a perfectly orchestrated machine capable of self-management. In case of illness, everything is planned so that he heals himself. But sometimes failures or malfunctions occur that medicine cannot yet cure: this is the case with many degenerative diseases, certain forms of cancer, or even genetic diseases. Man is not the only living organism to function intelligently. The animal world is full of species capable of self-healing, sometimes with means that man dreams of possessing.

In this book, I offer you an overview of the techniques and research of the medicine of the future and how they can or could help to treat certain diseases. I also offer you some advice to maintain your health thanks to natural solutions, which we all have available. Live healthy, live happily!
