The fact that you immediately jumped to the assumption that the only useful thing one could do with glucose testing is to diagnose diabetes or plan insulin doses is indicative of the failure of imagination endemic to the system.<p>Glucose testing is useful for all kinds of things; the fact that you yourself (and most doctors) don&#x27;t know that, or think that other people can&#x27;t be trusted with their own data without some Credentialed Professional to interpret it for them, is both insulting and limiting.<p>I don&#x27;t want to go back to a world where AT&amp;T had to anticipate the ways I&#x27;d want to use telecom.  Although sadly in some respects we&#x27;ve never left it.
