The shinbone is one of the preferable limbs for Mongolians. This is very ancient custom. If you eat to the dullness, you can be a dullard. This is famous saying. Mongolians prefer the normal fill of a child's tummy. Mongolians believe that if a mother eats a shinbone after her delivery of baby, she can get strenght easily. That is wht mothers eat shinbone's muscles and drink its stock: Mongols wash the new-born babies with its stock. One should never break a shinbone. But if a baby's ears ache, we boil the marrow of a shinbone and drop it into the baby's ears. The ailing of ears stops.
