For years I considered myself clumsy. I often lose grip of objects. I don't know if that is the right description b/c my hands will just let go. I also find that my arm/hand will occasionally jump if that makes any sense. It's not a twitch, but a slight move/jump. If I have something in my grip when this happens, I will drop it as well. I'm worried b/c I now realize that I'm not clumsy. This is getting worse as I get older. I'm 29.
