People look at things differently. Imagine going to a village in Southern Sudan and try to explain to someone there the concept of life insurance or retirement. Go to Vietnam and say retirement. Retirement in another country is your body is too racked with pain and your hands are too arthritic from the life in the rice patty fields, so you can't work anymore. So you move in with your son and his new wife takes care of you because that's how families work there.
