OP, a little off-topic, but it sounds like you need to do some hand maintenance to make your life a little easier!
there are a ton of ways to hydrate your hands. i like techniques you can employ that do their work while you are sleeping. you can put a coat of vaseline all over your hands and then cover them with cotton gloves or socks before you go to bed. it works, believe me. after a week or so of that you'll notice an immense difference. then it's just basic upkeep after that, maybe once a week or something.
