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.
Average truck driver pay-about .40 to .45 cents per mile, or $50,000 to $60,000 per year. Above average truck driver pay-close to .50 cents per mile, and over $60,000 per year. Of course, what you haul matters. Flatbed, step-deck and heavy-haul drivers add a little to that pay scale.
