People should get used to eating the jelly which comes from cooking the trotters or the head of a sheep or cow. This jelly binds the bones together. People who eat this regularly provide their bodies with a store-room of this. Every time the body needs it as a renovation, it will make use of it. It is like filling up the car with oil once the oil has been used. People who have a tendency of having problems with their disks should eat this jelly regularly every day, others every week.
