Heads Up, Pushing Every Hand Good Strategy or Not?

Actually, I already know the answer to that I think, this is not a very good strategy. However I read in a thread. perhaps someone can point me to it, that if you constantly push every hand the best someone can do to you is beat you 52% of the time or something. That doesn't sound right, but my HU game is a little weak so anything that close to splitting sounds good to me.
