Hands are for handling but we only have two of them and they are not enough for things we need more hands for that is why we ask people to help so that they can share their hands too. Since we have been created to be able to think far above how the animals think, we have invented so many things to be able to help us to make things easier and lighter. material handling is really a wise move to extend human’s capacity to handle things faster and easier. Yes, we only have two hands and five fingers each, but they are just enough to be able to maneuver man-made handlers.
