Many of my patients have had horrific childhoods, been involved in high levels of lifelong criminality, had severe mental illnesses, have serious drug and alcohol problems, and have committed several violent offences, including murder. After analysing and dealing with these characters all day, it's unlikely I'm going to be stimulated by Average Joe, his mundane background, and his mediocre chat.

Being a psychopath is not just about anger. It's about all these other traits that Hollywood may not have the inclination to research or portray. Maybe that's because they are not really that glamorous.

One thing that really struck me from getting to know the prisoners - there was the moral code they lived by. The code seemed bizarre and contradictory to a naive yet inquisitive man like me. Some staff members called it the "con code".

Like many other doctors, I am not against the principles of the Health and Social Care Bill or against the theoretical restructuring of the NHS. What worries me is the potentially misguided and hasty way it is being proposed. One only has to look at the outcome of the privatisation of rail services - dire quality and ever inflating fares.
