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.
The technical skill required to haul sensitive materials is rewarded with higher pay. The average truck driver is expected to travel between 2,000 and 3,000 miles per week, based on the 70 hour maximum hour restriction over eight days. Drivers that are just starting out can expect to see starting wages. Median wages for rookie truck drivers are between $0.27 and $0.29 per mile.
