As others have mentioned, learning as much as a I can about autism and particularly how females experience it is a current special interest. That's not too surprising since I have only been aware of being on the spectrum for about 6 months. Previously I had a very passionate special interest which was gardening, but more than the actual physical act, I spent hours and days and months reading books, learning botanical latin and making landscaping plans. I can no longer garden but have a passion for painting. I am also highly interested in social sciences, neurology, philosophy and I am a fervent atheist with a love of reading all things that support this whether it be science or the writings of people like Christopher Hitchens and Sam Harris. I love systems and I love design and colour so currently am obsessed with systems for figuring out what a person should wear based on lines of the body and colouring. There are many systems to explore, critique and learn from. This does not mean that I am obsessed with fashion or particularly stylish myself.
