Calcium stones are the most common. They can be made of calcium oxalate (most common), phosphate, or maleate. Eating fewer oxalate-rich foods can reduce your risk of developing this type of stone. High-oxalate foods include potato chips, peanuts, chocolate, beets, and spinach.
Differences in Pay. Long-haul drivers typically make the most money. Data from the Bureau of Labor Statistics shows the median annual pay for heavy and tractor-trailer drivers in 2010 was $37,770. Some short haul drivers' wages may be included but the BLS states most drivers in this category are long haulers. Delivery and driver/sales workers are described as those who pick up, transport and drop off packages within a small region or urban area. In 2010, their median annual income was $27,050.
For an experienced independent truck driver, the rate per mile could be as high as 60 cents a mile. This means for an experienced independent truck driver traveling an average of 70 miles an hour on the interstate can make an average of 42 dollars an hour. If the haul, or trip, equals out to 800 miles then the driver will make $480. This of course does not include his or her rates for accommodations.
