Modern man is accustomed to believing that he is in complete control of his body and health. We count calories, try to avoid viruses, buy vitamins and hope that our genes determine the duration of our life. However, revolutionary discoveries in recent years in the field of molecular biology and 4P medicine (personalized, predictive, preventive and patient-centered) prove that we are controlled by trillions of microorganisms.

For decades, popular culture and advertising have taught us that bacteria are dangerous enemies. We bought antibacterial soap that “kills 99.9% of germs,” took antibiotics at the first sign of a cold, and strived for absolute sterility. However, the modern biomedical revolution and the 4Ps of medicine (personalized, predictive, preventive, patient-centered) have radically changed this view.

Antibiotics are one of humanity's greatest discoveries, saving millions of lives. However, today they are often prescribed "just in case" at the slightest symptom of a cold.
