Invalided out of service in June 1941, Bradman spent months recuperating, unable even to shave himself or comb his hair due to the extent of the muscular pain he suffered. He resumed stockbroking during 1942. In his biography of Bradman, Charles Williams expounded the theory that the physical problems were psychosomatic, induced by stress and possibly depression; Bradman read the book's manuscript and did not disagree. Had any cricket been played at this time, he would not have been available. Although he found some relief in 1945 when referred to the Melbourne masseur Ern Saunders, Bradman permanently lost the feeling in the thumb and index finger of his (dominant) right hand.
