A book I have, "Cheiro's Book of Numbers" says that people born on the 4th, 13th, 22nd, and 31st "have a likelihood of suffering from mysterious ailments, difficult of ordinary diagnosis. They are more or less inclined to melancholia, and mental disorders, anemia, pains in the head and back, bladder and kidneys. Number 4's derive the greatest benefit from electric treatment of all kinds, mental suggestion, and hypnotism. They should be particularly careful to avoid drugs, also highly seasoned dishes and red meat. The months to be guarded against for ill health and over-work are : Jan., Feb, July, Aug., and Sept."

Cheiro died in 1936 so this is an older book.
