I can attest (though not for so long a time as that) this does work. Technology use nowadays (which is mostly entertainment or convenience) is mostly habitual. Unconditioning those habits, or replacing them, is healthy. And a note on privacy from state actors. Even if you could hear all the voices in the room, it would be hard to separate a single voice and hear it clearly through the cacophony. That's the current state of affairs with government surveillance. You are psuedo anon, like bitcoin, because it's hard to single out one person with all the noise. When you listen to all the Facebook posts, from the LOL cats to the fight clips, eventually, you tune out everything that isn't "I am a crazy head and intend to do harm to myself, or others".

So, just be aware you are always on record, if you use an electronic medium of communication. It doesn't diminish you, which is the most important thing. But it does give you some considerations.

But when they tune in, you are quite fucked.
