Another common type of kiddie ride is the miniature carousel type. These rides are usually in the form of a small-sized carousel and newer models have the coin-box on the main pillar whereas older units have the coin box on a pole sticking out of the side of the ride.
Degenerative disc disease (ddd) and arthritis are very similar, and often are considered the same. Arthritis, however, is a broader term that can include arthritis to any joint in the body and can include different causes, such as autoimmune, infectious, overuse, traumatic, aging, etc. Ddd is specific to the spine and refers to arthritis that is usually age or overuse related.
Degenerative disc disease is what occurs as typical age-related changes occur to the spinal discs. It can also be the result of obesity, years of heavy physical labor involving lifting, smoking, and sudden incidents such as an auto accidents or a fall. When the discs wear out, the space between the vertebrae becomes narrower, compressing the nerves and causing pain in the neck or back.
