A piece of food that penetrated Rabbi Yitzhak Kadouri's lungs caused the worsening of his health and his eventual admission to hospital earlier in the week, according to his doctor's Tuesday morning. Kadouri was unstable and in critical condition at Jerusalem's Bikur Holim on Monday. Reputed to be 106 years old, the rabbi was admitted to the hospital with a severe case of pneumonia. His doctors attached him to a respirator and induced a coma with anesthesia. He is being treated in the internal medicine department's intensive care unit by Dr. Yosef Kleinman, who is also Kadouri's personal physician and head of the department. His second wife, who is half his age, is at his bedside, along with several children and grandchildren.
