I am not quite sure why that is�.maybe we are becoming a more angry society, maybe we are expressing anger more, or maybe we are witnessing a paradigm shift. Perhaps we are shifting to a research paradigm that more readily recognizes and includes the role of psychological factors in disease�..psychological factors such as personality attributes and emotions, for example. Maybe the influence of Cartesian dualism is lessening and this paradigm is slowing being supplanted by a more inclusive theoretical model.
