and so confused......

ok, so this morning i noticed that i sign-in passwords with my right hand.....and use my right hand to type in many letters that my left hand could/should be typing.....this is a revelation to me, as i am left-handed.....i cannot seem to hold a pencil in my right hand.....so why do i favor it when i type?.......i tend to hold forks with my left-hand....but can manage to hold an eating utensil with my right hand,......such is the mechanics of survival, i suppose.........all this hand-confusion may be due to the arthritis-like pain i have in my hands and wrists this morning.....maybe my right hand is stepping up to the plate to give my left hand a breather.......
