2. Incest
It is dangerous for grown-up men to live in the same room with their grown-up blood sisters.People have been found guilty of incest (having sexual intercourse between near
relations e.g.brother and sister)and this is highly abominable. Adequate arrangement should be made for young men and young women to sleep separately as soon as they reach puberty(stage at which a person becomes physically able to become a parent; maturing of the sexual functions).
