Very matter of fact and sticking to the point. Fred has definitely put himself out there and bravely so. His research to see if obsessional behaviours and intrusive thoughts are more common than we think is a very complex one. Equally the search for the 'cure' and the examples used of other people's experiences (some being quite famous figures) is very interesting and eye opening.
As referred to by Fred, I have purchased the books Irrationality and Breakdown by Stuart Sutherland.
