In the modern world, you constantly have to rush somewhere. Before you have time to look back, half your life has already disappeared around the corner. I would like to recall the classic’s statement on this topic, but the trouble is, it doesn’t work! How so? Where did this knowledge go? Why does solving simple problems become so difficult over the years? Does our ability to think deteriorate as we age? Unfortunately, this is true! The older we get, the worse our ability to think. The brain seems to be starting to deteriorate. This process is inevitable if you do not regularly engage in brain development. This book presents a set of methods for developing the mental abilities of the brain. They will not only help you maintain mental clarity for many years, but will also allow you to open up new facets of your capabilities.
