April is Autism Awareness month. If you see random puzzle pieces displayed, that is why.
Head over to wired.com and take the test see how normal you are. If you are like me and score in the high 30's you can still live a normal life. If you know people who "think in pictures" and are unable to process emotions without resorting to logical methods they are probably somewhere on the autism spectrum.
There is a statistical link between left handedness and autism http://www.dana.org/news/cerebrum/detail.aspx?id=656 which has not been fully explored.
There is also a link between having a Y chromosome and autism that also has not been fully explored. http://www.psychologytoday.com/articles/200401/autism-whats-sex-got-do-it
Autism also seems to have more or less random associations with genetics and race. http://www.cdc.gov/mmwr/preview/mmwrhtml/ss5601a2.htm
Or you could just watch "Rainman" again, cause Dustin Hoffman was really good in that role or watch Claire Danes portray Dr. Grandin in "Temple Grandin". Trying to understand someone on the autism spectrum is probably as hard for normal people as it is for someone with Aspergers or Autism to understand normal people.
My wife has told me that if she could fix one thing it would be my "social awkwardness" and while I wish I could for her sake, that may be a bridge too far.
