Over the past months I have noticed that my hands tremble when I lay them out straight. I thought this was normal, so I thought nothing of it. A few days ago I asked my family if their hands tremble, and they don't. They suggested maybe it's because of my cubing hobby, and how I spam turns a lot. I have been researching this, and I doubt I have any neurological disorders. My question is: Do your hands tremble too? Is it cubing, or something different?
