This sounds like it was written in 2007 or something.
Google has been working on question answering for years now, but only exposes it when it is sure of the answers.

(I get a "one box" answer saying "November 22, 1963 John F. Kennedy, Date of death"). You'll note that Google had to derive that I meant "John F Kennedy" by JFK, that I wanted a date, and then retrieve the answer.
https://www.google.com.au/search?q=how+old+was+jfk+when+he+d...
"46 (1917–1963) John F. Kennedy, Age at death"
https://www.google.com.au/search?q=how+did+jfk+die
"Assassination John F. Kennedy, Cause of death"
It's worth clicking the "More info" button under one of these "One boxes". Google will tell you what it regards as "facts" and where it is deriving them from.
(Also, http://www.wolframalpha.com/input/?i=how+old+was+jfk+when+he... is just as impressive)
