== An opinion on what to include in the article == 

 In my opinion, responding to DavidWBrooks thoughts, since this list is short enough anyway, I think both can be included.  Perhaps a statement should be added to the top of the article to clearly define this article.  We know death by pneumonia is quite common, but in the way it happened to U.S. President W.H. Harrison, and the fact he was a famous person in history, merits a mention- in my opinion.  Technically, by definition of 'unusual death', i.e. cause of  
 death being very uncommon or rare, W.H. Harrison should not be mentioned.  Being struck and killed by lightning is very rare cause of death, so this would qualify by definition of unusual death. My opinions summarized:   

 1. We include deaths from famous people where very unusual circumstances contributed to death (although the death itself may be quite common, e.g. W.H. Harrison.)  

 2. We include deaths of noteworthy people where the death itself was very unusual, even though the circumstances that contributed to death perhaps were not. I would however omit any deaths due to rare medical conditions.
