@strypey no, not exactly... there's a lot of diversity within autism. So, some people are strongly affected by some of the autistic "traits" but others may have NONE of them...
@strypey hyper mobility is a SYMPTOM of an issue with connective tissues that some autistic people have... not being hyper flexible is no guarantee that someone isn't autistic but a person or child that is regularly dislocating or seems a bit clumsy or uncoordinated MAY have connective tissue issues which are often co-occurring with autism... 🙂
