A single elevated ESR, without any symptoms of a specific disease, will usually not give enough information to make a medical decision. Furthermore, a normal result does not rule out inflammation or disease. Moderately elevated ESR occurs with inflammation but also with anemia, infection, pregnancy, and with aging.
Between 65 and 81 percent of people can curl their tongues, and slightly more women than men can do it, studies find. The notion that a person's ability to roll his or her tongue is determined by a single dominant gene stems from a paper published in 1940 by geneticist Alfred Sturtevant.
-I would say towing up to 800 pounds with 200 pounds of tongue weight is perfectly fine, as the Volt can hold up to 4 people, towing 800 pounds is not much more work. Just take it easy and the car shouldn't complain.
