Q: From what disease did J.F. Kennedy suffer?
A: Addison’s Disease. During the 1960 presidential campaign, rumours surfaced that candidate John F. Kennedy was suffering from Addison’s disease, an incurable, potentially fatal deterioration of the adrenal glands. If true, the information could have influenced the outcome of what ended up being a very tight election. But Kennedy denied it, and the press, as it would later do with other unsavoury talk about the Kennedy clan, let the matter rest.
