People ... normal people, never think about Asperger's. It doesn't come up in normal conversation... ever. No one mentions it in the news, or talk shows, or regular TV, or newspapers. Bipolar disorder, kleptomania, autism, schizophrenia, psychosis, narcissism, come up far more often than Asperger's. I bet if you stopped a 100 people on the street, and asked them what's Asperger's? ... maybe two or three would know what it is... and if you asked, what's ASD? ... even less. However, people with ASDs ruminate about it for a couple of hours a day.
