I have been saying for a long time now that the language we use and the images we watch adversely affect the human brain. Our brains are structured by the world around us, the words, the images, the overt emotions people display when happy, sad, disturbed, angry and disenchanted. Critics dismiss the evidence because we live in a self-perpetuating and competitive system, which for reasons of capital growth, is unlikely to change. We copy others because it seems to be in vogue. No one wants to be different. We need to change. We can change individually. We can be mindful of our speech and our behaviour. If we are to create a better non-violent world then we must look at those behaviours we dismiss as normal, because acceptable they may be in this modern age, harmless they are not.
