I switched the radio on today part way through a discussion with Professor Clare Mcglynn . Her new book is The rise of Extreme porn and how we fight back.
I'll listen to the whole of the interview later but what I heard was extremely interesting. It ranged from the insidious effects on society of the wide spread viewing of porn, the legislation and implementation of laws on extreme porn etc. She is calling for a publicity campaign to inform women of the damage done by strangulation - she likens the effects of this on the brain as similar to repeated concussion.
