It is a difficult question why adults dye leaving their children. It is may be because of HIV, hunger, poverty. However, I think it is because parent's love of their children. If I have a children, live there, and we are so poor, I want to let my children eat as many as possible. I will give all food. It I had some money, I will buy them some clothes. That is, I will give them what I have. Therefor, parents cannot live longer.
