It has been said,  and I've repeated it often, "everything you know is wrong."~Benny Podda

Well...everything you are reading right now, is already out dated. Everyone is thinking they have the latest and greatest, scientifically proven, under the bar based "secret".

Ready???  BULLSHIT!  Complete nonsense.  You want to be on the cutting edge?  Try  this:

Think, Apply, Adjust, Adapt, Succeed or Fail.

Stop what you are doing.  Leave the computer (give your eyes a rest) and go do something!  This is utterly insane.
They're not "edgy".  They are on line, exercising the intrinsic muscles of the forearm by TYPING...NOT exercising.  (and they have the forearm development of an infant to boot)
