I've never seen that happen. In fact, you can include immunity to all diseases in that list. Unless you RP catching the cold, or an STD from that time you took your men to a brothel, or radiation poisoning from activating portal stones like an idiot, you never ever fall ill. Pretty cool to be a non-heroic noble.
I heard that at a certain age you can get random wounds, but I am not sure whether such rumor is true. loren is about the only one who can confirm or deny that.
