Priya Nath had been regularly taking Shri Nathji’s weight and had been measuring the amount of fluids that he took every day, as also the urinary output. He would then make calculations to see whether the amount of fluids he took exactly equalled the amount voided. This was to ensure that no extra water was accumulating inside the body due to heart failure. Breakfast Tea = 250 c.c.He had read in medical books that the body made 150 cc of water inside itself from the chemical reactions of the food. And thus he calculated that Shri Nathji had taken 1700+150=1850 cc of water.
