Grinding or crunching are common symptoms of cartilage problems. If the cartilage is damaged -- a condition called chondromalacia -- a crunching sensation is often felt by placing the hand over the kneecap and bending the knee. A similar grinding sensation may be felt with knee arthritis.
Don't get confused by the name. It was just the civil code that Napoleon Bonaparte established in France. What was significant about it was that it replaced the feudal system, the major governing system since the early medieval period, establishing a civil legal system. It also influenced other civil codes throughout Europe (even though it wasn't the first in Europe).
The French under Napoleon would become united, strong, and most important equal. Napoleon brought stability and direction to a country without a course. His unification of France would have a profound impact on not only Europe, but the entire world. Napoleon was born August 15, 1769 in Ajaccio Corsica.
