William Taft who was the U.S. president between 1909-1913 once got stuck in the White House bathtub.
A man went to the hospital with a suspected malignant tumor in his left kidney. Several tests were made but the results were all negative. Nevertheless, the man insisted on an operation to remove the kidney, why?
The man's son had been on a dialysis machine for years and his condition was deteriorating. Now his only partially working kidney was found to have a malignant growth and had to be removed. Although the doctors still hoped to find a suitable donor for a transplant, the father decided not to risk further delay.
