things that will...

... be impossible. Or possibly really frustrating when you attempt with only one hand, or just extremely aggravating, and  poorly accomplished if forced to try with your non-dominant hand. A plethora of daily insignificant tasks that frequently turn into monumental obstacles when you find yourself literally hand-y-capped.

It is almost impossible to put on your socks. You don't think about it, when you routinely do it day after day. How you tuck your thumbs in on each side and pull it up over your toes, over foot and past the ankle bone up your leg. But when you cannot pinch between your thumbs and forefingers, but only have one hand engaged in the attempt, it is seriously difficult. Likewise tying your shoe laces. If you do actually it tied into a bow, be assured it will not stay put for long, and will soon be flapping, in need of attention.You have to pull both loops tight, something that cannot be done with only one set of fingers, pinching and pulling.

Brushing teeth with the hand that has never done it is most unsatisfactory. Try it, and you will soon discover you feel hopelessly inept. Your brain will be telling the hand what to do, but your hand will simply not cooperate.  It is such a simple task when you allow the hand that has been doing it since you were three years old to take care of your mouth. But the on the other hand, the newly recruited one will be unable to complete the assignment. Better than feeling like a cat slept in there, but very poorly done.

Remarkably difficult to feed yourself. Spooning food in works much better than using a fork, as things tend to fall off the fork before arriving at the opening in your face. Plus, if you plan to consume anything that needs to be cut into bite sized pieces, you'll have to borrow the use of another hand to help hold it down. It takes two hands to operate a knife and slice.

By now, you should be Very Thankful both of your arm extensions are in good working order. You also cannot put a button through a button hole, or zip anything: simple tasks that require both left and right to accomplish. Using scissors is beyond daunting. Or measuring the detergent to go in the washer. Operating a can opener so you won't starve: forget it!
