" Consumption is a universal phenomenon. All humans consume varieties of products, many of which beyond actual necessity, because it activates the brain's reward center. And the more a certain product activates the reward center with its unique characteristics or its predominant social stature, the more that product gets chiseled into the long-term memory of the consumer, making it a fundamental part of the individual's psychological well being. Thus the human mind grows a deep psychological bond with a product. And this bond can grow so strong in time that it would defend itself from all sorts of criticisms. It is the brain's way to maintain its internal purely individualistic well being. Hence, a strong psychological bond between the mind and a product slowly not only becomes invincible to criticisms, but also, develops its own cognitive immune system against such criticisms. "
