I'll try to keep it short. These are the things I love doing, even though I sometimes don't have the energy for any of it, except lying in my bed. Being autistic can be quite exhausting.
...tinkering with alternative operating systems for notebooks and smarties.
...watching Star Trek - grew up with it and just don't get tired of (re-)watching. My fav is Voyager.
...playing video games - my favs are Loz - Breath of the Wild and Horizon - Zero Dawn
...reading - mainly SF, fantasy, and non-fic. My fav authors are Stephen Baxter, Robin Hobb, and Henry David Thorau.
...strength training - one of my rooms was turned into a training room.
...cycling - I own an almost 20 years old Specialized Rockhopper and prefer day trips.
...travelling and hiking with my GF - mainly in remote areas such as Lapland for example.
... lying in my bed, since it is the one place with the least sensory triggers.
