Dear young people! I have an advice of great importance for you- do your best in order to become the perfect father before you want to get married; the time of getting married is late; from the very moment try to get rid of the moral vices in you and purify yourself of them; be careful where you go and who you interact and what food you eat- there is a substance in sperm by the name of gene that transmits all your characteristics to your generation.
