Wikipedia:Articles for deletion/List of United States Presidents by longevity
You are mixing points. Yes what they did post-presidency is important and a coverage of research and encyclopedic but not their longevity. Your opinion seems to constitute  by surmising that those who live longer are given benefit of doing more work than those who live short, but that goes for any person. Live longer, do more. Live short, did less
