It is the duty of children to take care of their parents when they get old. Parents sacrifice their whole lives to raise their children. They work hard to raise their children throughout their live. They sacrifice their happiness, peace and careers to take good care of their children. Therefore, children should take care of their parents at their older age because they do not have the capacity to take care of themselves. For example, in Bangladesh parents are mainly taken care by their offsprings. This is a common practice in Bangladesh because many people believe that children are responsible for the well-being of their parents.
