Wikipedia: Cirrhosis
Cirrhosis is a condition in which the liver does not function properly due to long-term damage. This damage is characterized by the replacement of normal liver tissue by scar tissue. Typically, the disease develops slowly over months or years. Early on, there are often no symptoms. As the disease worsens, a person may become tired, weak, itchy, have swelling in the lower legs, develop yellow skin, bruise easily, have fluid build up in the abdomen, or develop spider-like blood vessels on the skin. The fluid build-up in the abdomen may become spontaneously infected. Other complications include hepatic encephalopathy, bleeding from dilated veins in the esophagus or dilated stomach veins, and liver cancer] Hepatic encephalopathy results in confusion and may lead to unconsciousness.

Cirrhosis is most commonly caused by alcohol, hepatitis B, hepatitis C, and non-alcoholic fatty liver disease.[1][2] Typically, more than two or three alcoholic drinks per day over a number of years is required for alcoholic cirrhosis to occur.

Wikipedia: Round Table
The Round Table is King Arthur’s famed table in the Arthurian legend, around which he and his Knights congregate. As its name suggests, it has no head, implying that everyone who sits there has equal status. The table was first described in 1155 by Wace, who relied on previous depictions of Arthur’s fabulous retinue. The symbolism of the Round Table developed over time; by the close of the 12th century it had come to represent the chivalric order associated with Arthur’s court, the Knights of the Round Table.

29 June 1968, Indianapolis (IN) News, “Don’t Quote Me” by Bill Wildhack, pg. 17, col. 2:
“I know of several politicians who should be given the title of Sir Rhosis.”
