Exist some "light" autism (that maybe I have?) and CAPITAL Autism (that my twin have). The second? It impair life so hard is impossible to live without constant help. The kind of autism most people talk, like the one that is so "good" that you could actually have a nice Job on Dell and others, maybe is hard to diagnose. That is the reason to say is a "spectrum" But autism that is in the hard side of this spectrum? Is impossible to miss it.
