PERSONAL INJURY; PAIN AND SUFFERING; NO DEFINITE STANDARD
No definite standard [or method of calculation] is prescribed by law by which to fix reasonable compensation for pain and suffering. Nor is the opinion of any witness required as to the amount of such reasonable compensation. [Furthermore, the argument of counsel as to the amount of damages is not evidence of reasonable compensation.] In making an award for pain and suffering, you shall exercise your authority with calm and reasonable judgment and the damages you fix shall be just and reasonable in the light of the evidence.
