A very interesting article in this summer's Smithsonian Mag. about a forensic pathologist in Italy who has examined a lot of medieval and early modern bodies (inc. some famous ones).
Short version: medieval & Renaissance aristocrats endured a much worse level of everyday health than we tend to imagine. (Status didn't exempt you from parasites, & armor-wearing from an early age predisposed noblemen to severe arthritis at an early age...) People sometimes did die unexpectedly of unglamorous natural causes, like malaria. But sometimes they killed each other with arsenic.
Just as a related addendum, I have noted in my own research on 17c French nobles that that they really were much less healthy overall than most of us are today. This isn't even including life-threatening conditions, just everyday fevers, digestive woes, abscesses, rotten teeth, etc. they mentioned in passing -- if you didn't find yourself confined to bed with some painful ailment two or three days a month you were exceptionally robust & people remarked on it.
