How does a biometer works and can one block its functioning I am refering to the ones that can detect when you are about to fall sleep or you are in a deep sleep or feel anger happines etc?
I do not believe that research has established the credibility
of the biometer as a legitimate scientific instrument. That is, I
do not believe that it really produces useful, realible, valid
information. If you are angry, or happy, do you need an instrument
to tell you that you are?
