Old men and women, for whom Fasting Causes Extreme Hardship
Issue No. 1450- The elderly can leave fasting if it is hard for them to observe fast. However, they should give one mudd (750 grams) of wheat, barley, etc., to an indigent for every fast. It would be better to give bread instead of wheat or barley. In this case, the obligatory precaution is that the net weight of the wheat of the bread be equal to one mudd.
