I'm Brian and so's my wife

Since I went 'public' about my ASD diagnosis I've had more than one person say to me 'We're all on the spectrum mate'. At the time I found the comment slightly offensive, as if they were saying, 'You're not the only one who's got issues, just get over it', but on reflection, perhaps they have a point. In this crazy world where the borders of 'normality' are infinitely blurred, could it be that we are all on one big spectrum, but only some of us in the 'zone' that is currently classed as a disorder? I can't help wondering if everyone did the tests and questionnaires that I did when being assessed what percentage of the population would be diagnosed. The very first test I did came as quite a shock because the questions seemed so very appropriate to how I was feeling, and it returned a result of high probability. I can't decide if that's just because I do actually have ASD or because some of those questions would apply to anyone doing the test. I'd be interested to hear people's opinion on this, especially if anyone out there has done the test and returned a negative result i.e. low probability.
