The news constantly alerts us to bad events in the present. The doom-laden feeling that this creates in us is then intensified by our inability to remember the past; our historical knowledge is rosy and pink and we fail to remember that, one year ago, or ten years ago, or 50 years ago, there was the same number of terrible events, probably more. This illusion of deterioration creates great stress for some people and makes other people lose hope. For no good reason.
