I discovered I'm autistic very recently thanks to the internet. I also have what ten years ago would have been called Asperger. Today many people still use the term but it is actually obsolete since 2013, when it was merged with autism into the Autism Spectrum Disorder (ASD). Asperger was considered a different thing for decades becasue people with Asperger are on average considereably less impaired in social situation than people with classic autism. It is actually the same thing and to further distinguish autistic people the three levels of autism have been introduced. So people with what was Asperger are now level 1 autistics and people with other "more severe" forms of autism are level 2 and 3. This has only to do with how much help and accomondation they may need and has nothing to do with the autistic traits, which are diffrent but consistent for all autistic people. When I was a kid I was also very interested in different vehicles, though mostly sailing ships from the 18th to 19th century and utilitarian cars from the mid 20th century. Most kids loved football and pokemons but I prefered going to a museum.
