OCD - Obsessive Compulsive Disorder. 3% of Australians have this. Now a pop culture word for anyone that is overly 'neat', we clarify what it is exactly. What makes a detail oriented person with extraordinary hypervigilance morph into their behaviour becoming disordered and paralysing? Is there a cure? What makes the brain function as such? Why are athletes such as Rafael Nadal and Steve Smith using OCD like ritualistic behaviour on the field? Is this merely 'behaviour' in high stress situations, a perfectionist personality, supersitition or OCD? Is there a role for mental illnesses as such in society that we are not fully acknowleding? The tale of the 'Canary in the Coalmine' explains this.  Psychiatrist Dr Nicholas Cassimatis clarifies all of this, as simply as possible, in a clinical sense rather than a pop culture sense.
