The real reason for heated tables.
Regionally, it varies as to "why" the tables are heated.
In Northern European countries, the tables are heated to thaw the ice off the cloth and to warm the cold-blood of the players.
In Central America, South America and the Philippines the tables are heated to remove the moisture caused by monsoon rains and tears of frustration from the cloth.
In Korea, it is a combination of the first two.
In Italy, Turkey, and Spain, it is because the players are too cool for their own good, and it reminds them that they are not that hot.
In the USA, it is because all of the players are so old that the heat helps sooth their rheumatism.
Remember folks, in the heyday of American Billiards, Hoppe, Schaefer and Cochran didn't play on any newfangled heated tables - and they played with balls 1.2mm smaller!!!
