No science has aroused such public interest in recent years as the study of the brain. We are beginning to understand better how our brain works, how it assimilates, classifies and stores information. But one discovery may be especially exciting for everyone: the brain does not age! And thus, the common stereotypes about sclerosis and senile insanity no longer correspond to reality. The brain is like a muscle that can be exercised. The mental exercises of various directions collected in this book will help you stimulate, along with classical logical thinking, also creative and lateral thinking. Even if you think that you understand your thoughts well enough, the book will show you thinking from a completely new, surprising side!
