i think i may have this ever so slightly, but if i try i can hold my hands still, but if theyre just relaxed then they have a very slight shake to them, my dads hands were like that too. I remember when I was a kid and used to build model cars hed watch in amazement how steady my hands were. my g/f has it too, hers is slightly worse than mine. its nothing anyone would ever notice though, unless ive been working w/my hands alot, then they shake quit a bit.
