1. Fixing Appliances--Rates of electrocution deaths among men jumped 76 percent between 2008 and 2009. The most common cause is trying to fix small appliances like toasters or blenders. Unplug everything before going to work.

2. Lighting Fireworks—About 9,000 people end up in the ER every year as a result of messing around with fireworks.

3. Boozing Near a Body of Water—About eight adults die every day by drowning-and 80 percent of those victims are men. In 70 percent of those deaths, alcohol is involved.

4. Hanging Your Own TV--Between 2009 and 2011, about 19,000 people were sent to the ER--and 215 were killed--by falling televisions. Unless you really know what you're doing, have a professional install your new flat-screen for you.

5. Working with Jerks--People who get high levels of social support from their colleagues also enjoy a 41 percent drop in mortality—but a lack of support in the office has the opposite effect. A lack of friends in the workplace could lead to more work stress, which would explain the higher mortality rates.

6. Cooking with Gas--Grilling results in about 17,000 serious accidents annually and many of those involve propane grills. Explosions are pretty rare, but fires are more common and they're usually due to mechanical failure.

7. Sitting Down All Day--The more time you spend sitting each day, the greater your chances of dying an early death--regardless of how much you exercise. Sitting for long periods in your car, at work and on the couch at home is your ticket to an early grave.

8. Driving the Day After a Snowstorm—The storm has passed so you assume the roads are safe enough for you to return to your usual driving speeds and habits. But that leads to a rise in accidents and fatalities the day after snowstorms. That’s because the roads could still be slick.

9. Working the Night Shift—Melatonin is the hormone that helps regulate your sleep cycle. It has been linked to lower rates of killer diseases like prostate and lung cancer. But if you go to bed well after dark and sleep during the daylight hours, your body's circadian clocks can be thrown off balance and that can cause a big drop in melatonin levels.

10. Texting--You know texting and driving is dangerous, but messing with your phone while walking could be just as bad. The number of emergency room visits among people who were trying to text while walking jumped 35 percent between 2009 and 2010. So the chances of a tree trunk or telephone pole meeting your face in the near future are going up
