A person may live with defective teeth for years, or perhaps 

 with none at all, yet we know that such persons seldom enjoy 

 their food or good health. Surely, if the birds do not have the

 healthy nor derive the greatest benefits from their food. In 

 consequence they cannot be expected to give their master a good 

 return for their food and care.
