The imaginative manual is designed not only to practice the memory and reveal its weak points, but is also suitable for entertainment. Part of the book is devoted to theory - what the brain is, what it is made of, how it works, what types of memory we have, the process of storing memories and the aging of the brain. It discusses the factors contributing to the wear and tear of memory as well as its disorders and diseases (dementia, Alzheimer's, heart attack) and gives advice on how to maintain and improve memory. The main part of the book contains over ninety practical exercises - number series, pyramids, pictures, addition and much more.
