So your sitting on your couch watching TV. When all of a sudden you think to yourself I’m going to go get some orange juice. Not I need a drink or I’m thirsty. Orange Juice. Such a specific thing that your brain attaches it’s self to. Well your doctor will probably tell you thats your body’s way of telling you your short on vitamin C. Craving milk, low calcium. Meat, low on protein. Your body is pretty complex and knows exactly what it needs and has ways of telling you with out you even knowing your being told.
