What is a good way for me to prove that i do not have autism or asparagus syndrome?

Why do you ask?: It would be unusual to be a 37 year old with autism and not have been diagnosed earlier. An exception might be someone with the diagnosis of aspergers whose only noticeable difficulty was social interactions. If you feel you are functioning fine from a professional and social standpoint you do not have to prove anything. If you have concerns start with your primary provider to provide guidance.
