From Americas Most Stressful Cities 2010

Workaholics keep Houston tense
The economy in Houston, Texas, is relatively healthy--unemployment is below the national average--but prosperity may come at a price. Houstonians work the longest hours of any city we ranked; an average of 41.2 hours per week.

Furthermore, that toil isn't always rewarded with a solid insurance package--the city also has the highest percentage of people without any type of health care, at 25%. Grueling work hours can add to anxiety and a lack of health care means that stress-related illnesses will go untreated.

In many cities, stress is the price locals pay for other advantages. In Houston, for example, workers may burn the midnight oil, but they are rewarded for it with median household incomes of $54,811 annually, 4.8% higher than the national average, according to the U.S. Census. Lots of stressful cities also have plenty to offer that outweigh the stress for some. Las Vegas and New York, for instance, were tied for "coolest" cities in a recent Forbes poll.
