This story is one of many that really help to hammer home the message that your employment has a tremendous impact upon your quality of life and not just from a financial perspective.
It impacts your mental and physical health in dramatic fashion. Just think, if you hate your job not only does it make you crazy but now we see that in addition to the stress if you are commuting long distances it can make you fat. How about a Big Mac, or do you want to be a dope.
Not very surprising to read this, but it does assist in reminding us that when we evaluate potential employment we should consider quite seriously things like the commute as well as money/benefits/advancement.
