Essential tremors.  20% of people get them. They come and they go.

I use to thread a needle with my hands. Now, I can’t even pick my nose. I call it shaky hands and that’s how it goes. I just wish they’d let me know what keyboard key executes a function.  Anyway, shaky hands  on the computer keyboard creates opportunity. I usually screw up what I’m writing, not knowing which key or that my hand has inadvertently struck a key. Whatever I was writing simply disappears. That, in turn, frees me to shake  something else.
