The House we live in

From Dr Stone’s Health Building book:
“Our body is like the house we live in; when the electric currents are on, then light and heat are available. when the water pipes are in good shape and water is pumped through them by pressure, then all the fluid requirements are solved. When the gas is turned on, then cooking and gas heating are possible. And when the drainage is not obstructed, then the sewers do not back up and no regurgitation of drainage is pocketed in any part of the basement.”
