Scientifically, to naturally bear twins during pregnancy, a family history of having twins in the family must be present in either the female (mother) or the male’s (father) part. Some families want to have twins and some do not. In the Philippines, old people believe that a pregnant woman who is fond of eating twin bananas will probably have twin babies. Though Filipinos are aware with science (biology), they tend to believe the older people about this because they grew up with this kind of orientation, especially those who are living or once lived in a place away from the cities.
