Acupressure by studyingPressure Points
(So Keep Walking)
Just watch this nice picture securely .The Organs of your body have their sensory touches at the bottom of your foot, if you massage these points you will find relief from aches and pains as you can see the heart is on the left foot.
It is indeed correct since the nerves connected to these organs terminate here.
This is covered in great details in Acupressure studies or textbooks.
God created our body so well that he thought of even this. He made us walk so that we will always be pressing these pressure points and thus keeping these organs activated at all times.
