The well respected mental health campaigner, Janey Antoniou, died in hospital in 2010 while detained under the Mental Health Act. Her husband, Dr Michael Antoniou, talks to Claudia Hammond about the circumstances of his wife's death and why he believes it's wrong that hospitals, when a patient dies, can investigate themselves.

Also in the programme Claudia talks to psychologist, Sonja Lyubomirsky, about new research which shows that parents are happier than non-parents but surprisingly, the effect is greatest for men.

Claudia visits Europe's largest club drug clinic, part of Central and North West London NHS Foundation Trust, a year after it opened to find out about a growing use of so- called legal highs and the problems associated with legal and illegal club drug use.
