We've all heard that all work and no play makes Jack a dull boy. But might it make him a sick boy too? According to this study from MSNBC, it just might.

I know I've heard people complain about their jobs more times than I can count. I don't think I've ever had a job I despised, but I imagine it's not great for you. Dreading going in to work every day must be really bad for your mental healthy, and probably in turn makes you feel ill all over. High-stress jobs can also make your health decline, causing problems like headaches and fatigue, but also more serious ones like heart disease, stomach ulcers, and obesity. Especially in this economy, some of you might feel like work is more of a chore than a joy.

If you're feeling like your job is making you ill, it might be a good idea to take a break. Take a vacation day or a personal day and just relax. We all deserve to feel good about our jobs and ourselves. Good health is a really important part of that.
