Dear parent! You pick up this book, but I have to warn you that it is not for you. It's for your children. A son, a daughter... Maybe a nephew or niece. Or another young person for whom you wish well. And safety. Precisely safety, because today, as indeed always, the main thing is the preservation of life and health. Of course, we, as parents, will protect, protect, nurture and cherish. As far as our strength and capabilities are sufficient. But, alas, they are not limitless. And perhaps the wisest thing we can do is teach our child not to get caught up in stories. Get out of difficult and dangerous situations. Fight for your life and health. So do you need this book? Decide youself. I confess: when I warned you that she was not for you, I was lying a little. After all, in order to show the way to another, you need to walk it yourself.
