You have two adrenal glands. Theyâre located on top of each of your kidneys. Theyâre part of your endocrine system, a collection of glands that produce hormones. While theyâre small in size, your adrenal glands are responsible for numerous hormone-related functions in your body. As a result, disorders that affect your adrenal glands can have a broad impact on your health. If you suspect that you have an adrenal disorder, talk to your doctor.
That means it'll be perhaps 30-40 years before the very last of today's non-SD cars/trucks/buses is sold. By then, the average new car will last even longer than they do now -- perhaps 30 years and 300,000 miles. In total then, the last of the non-SD cars will retire about 70 years from now, in 2085.
Polk said the average age of all light vehicles on the road now stands at a record high of 11.4 years. That's up from 11.2 years last year, and 10.9 years in 2010. Beginning in 2002, when the nation's car and light-vehicle fleet was an average 9.8 years old, it has continued to rise in age for 11 consecutive years. For passenger cars, the average age has hit a record high of 11.4 years, while the average age of light trucks has increased to a record 11.3 years, Polk said. The latest data is based on a review of over 247 million U.S. car and light truck registrations in January, Polk said.
