'The main thing this book talks about is how to grow up healthy and learn to take care of yourself first, and then your loved ones. Discussing issues of personal hygiene, consent and respect for yourself and others helps you decide on something important - what kind of person you will grow up to be, and also lay the foundation for a happy life right now.' - TATYANA NIKONOVA, sex education activist, author of the blog @nikonova. online

'Finally, there is a crash course for boys on puberty: competent, scientific, simple. I was pleasantly surprised that the book pays attention not only to the stages of puberty, but also to the psychological and social health of boys, and also mentions the three pillars of health: nutrition, movement, sleep! A reference book for boys who want to know more about their health.' - YULIA SIDOROVA, pediatric endocrinologist, author of the blog @ j. sidorova

'This book is like a friendly conversation with an older brother: interesting, with humor, about important issues for every boy, worrying him in the process of growing up.' - VERONIKA MUKHAMETZYANOVA, social anthropologist, psychologist, author of the blog @truemama1
