Researchers offered many theories about things, contributing to mental work: from crosswords to physical exercises and cold shower. However, finally, all scientists came to a conclusion that way of life and food we eat affect brain work.
 
The most important foods, assisting brain work, are dark chocolate and slices of cold boiled meat, scientists assure. And sex, according to them, is the best way to keep sound mind till extreme old age.
 
Those who want to improve their mental faculties should quit smoking, watching “soap operas” and communication with people, complaining about their life constantly. Instead, it is useful hugging with children, making cribs, speaking at a meeting and reading aloud.
 

All these aspects are described in a book “Teach Yourself: Training Your Brain” in detail.
“Foods we eat and drink, the way we study at school and our mood at this moment - all this is of decisive importance. Correctly chosen way of life can constantly increase mental facilities, regardless of one’s age” - author explains.
