You may also experience neck or back problems from being hunched over a desk many hours a day. But you can tell everyone it’s from an old football injury if you think it will make you feel better. Get a little sign for your desk that says, "Full Contact Accounting".

And happen to have a large baseball bat handy, the Louisville Slugger kind that Cary Underwear sings about post her American Idol stint.
Our advice: Learn to duck duck like a hungry goose.
