He approached the task extremely seriously: he invited the best experts, met with prominent scientists and went through thousands of tests and training. And he described his entire experience in a fantastically fascinating manner. Whether the author ultimately managed to surprise the doctors with his powerful health or, on the contrary, he turned into an eternal patient, you will find out by reading this amazing, hilarious and fascinating book.
