ELI5: If I have 'high blood pressure', why can't I just cut myself a little to reduce the pressure?

It is not the amount of volume.  It is the pressures inside your blood vessels...and therefore your organs.  Blood letting would not cure hypertension.  It might lower your blood pressure do to hypovolemia (loss of volume) for a period of time, but when your body recovers you will still have hypertension.  And those damaging pressures on your organs, kidneys and brain specifically.
