This epigraph is very correct for the Russian Federation today because the average Hfespan of Russian men in this country is 57 years (Russian women are living on ten years more). It is statistical data. Russian scientists are an exception. Particularly, the majority of contributors of this volume are older then 60 and the editor of volume is older then 75.
We can explain this exception (phenomena) if we take in account the next Russian proverb: "All illnesses are from nerves and only a small amount from pleasure". We expect that readers immediately are thinking about sex as a part of pleasure. It is only partly right. Alcohol, tobacco and narcotics should also be included in the "pleasure" part. Unfortunately, the Russian people are world champions for drinking. The average Russian man (including ladies, children and even babies) drinks 18 liters of pure ethyl alcohol (calculation done in pure alcohol) per year. It is twice more than twice the critical amount (9 liters).
Russian scientists arc again an exception because the majority of them have pleasure only in the case of communication with SCIENCE!
Now we should remember the Kazakh (people living in the Asian part of former USSR) proverb: "If sixty years are coming the mind (brain, memory) will go back (to childhood conditions)". We expect that this proverb is also not correct for Russian scientists. As evidence of this opinion you can read the chapters of this volume where the most part of chapters were prepared by scientists from Russian Research Centers and from Research Centers of former Republics (now independent states) of the USSR.
It is now the right time to remember English proverb: "Please eat one apple every day and you will not need a physician" (it is a reverse translation from Russian to English). We do not know exactly if it is enough to eat one apple a day to be permanently healthy or not. We do know that positive emotions are in favor for good health. We expect that this book can (should) give only positive emotions to readers and we are waiting for the opinions of readers in this case...
