5.Andrew Jackson
No. 7 (1829-1837) This hot-headed president was involved in many duels and battles during his life and was generally in poor health. In 1832, a bullet left in Jackson’s arm from a gunfight 20 years earlier began to cause him intense pain. Jackson gritted his teeth as the surgeon made a cut, squeezed his arm, and popped the bullet out. His overall health improved afterward, leading his doctor to believe the bullet may have been causing lead poisoning.
6.Franklin D. Roosevelt
No. 32 (1933-1945) The Secret Service went to great lengths to hide it, but Roosevelt was paralyzed in both legs after he got polio in 1921 at age 39 — well before he became president. His wife Eleanor said the disease was a blessing in disguise because it «gave him strength and courage he had not had before.»
