Africa is a poor country.There names give children surviving to 10 years.In Africa, high mortality.Unlike Russia,Africa,no, not medicine,not happy people.The authorities do not care for the lives of citizens.As I live now in Africa,maybe in Russia it lived only during the second world war.Also a very large population,and almost all the people there are poor.There are no laws,no rules,generally in a neglected state for those who are not lucky.
