Are you a workaholic? Do you work more than 10 hours a day? If so, you may be doing damage to your heart. So says a study from researchers from the United Kingdom, Finland and France published in Tuesday's European Heart Journal.

The Whitehall II study, which tracked more than 10,000 British civil servants since 1985, suggests that adding three or more hours to a seven-hour day increase the chances of heart attack, angina and death from cardiovascular disease by 60 percent compared to people who don't work overtime.

“Employees with the highest risk of coronary heart disease claimed to work 11 to 12 hours per day, a most unusual work pattern certainly in the European context,” wrote Gordon McInnes, a professor of clinical pharmacology at the University of Glasgow. “Overtime-induced work stress might contribute to a substantial proportion of cardiovascular disease.”

Employees may be able to shave some time off their work day by working in a virtual office. Virtual offices set the stage for greater productivity and less stress. Rather than fighting the traffic, this telecommuting option allows you to work from a home office. By starting your work day before most people get to their desks, you can take advantage of that quiet time in your virtual office to work without distractions. Ultimately, that can help you accomplish much more in much less time.

A virtual office also drives productivity by letting you tap into technologies and services like web conferencing—which limits time-consuming face-to-face meetings—and virtual receptionist services that can screen calls so you aren't interrupted while working on an important project. If we are to believe this study, a virtual office could actually play some small role in saving your life!

A virtual office is also less expensive than traditional office space. You can rent a virtual office for about $75 in many metropolitan cities around the United States, like Atlanta, Detroit, Boston and Los Angeles. That gives you a prestigious business address, an 800 or local phone number and access to conference room and day office space if you need to meet with a client in person.
