Dr EMILY HENDERSON: I'm sorry, Mr Bridges, that you don't find this as fascinating as I do. But, really, it is. Just listen for a minute. The social model of disability is what they call the UN convention's version of this definition. It is a definition that focuses not on medical problems, not on disability as something to be treated, something to be fixed; it focuses on the idea that people with disabilities can live good lives, provided we facilitate.
