I've had a problem since day 1 - (that was somewhere in 1980 I think). The work "Luck". It appears everywhere - working on roulette constantly I see/hear/read it many times per day. There is a major problem here, and that is that "Luck" isn't a really "thing". It's a word that is used to throw into a sentence to "explain" something - when in reality it doesn't. There are perfectly good - legitimate explanations for why things happen. Perhaps people who don't understand probability simply use it - or plug it into a sentence to explain what they don't understand. (and this has always bugged me). There are lots of words like "Luck" that aren't real things - that people use everyday to explain things. My pet peeve though is this word. If a person goes into a casino and wins, they are "lucky". It people play their "lucky" numbers in the Lotto and win - it was the "lucky numbers" that won. If any good fortune comes to someone out of nowhere, it is lucky - bad things happening... "Well, he was unlucky" I like to put Luck into the same category as religion (prayer, faith) and some emotions that are described nicely but don't exist as a "thing". (I'm a realist by the way). Wikipedia has a 1/2 decent page on it - explaining it's origin and use and meanings, etc. https://en.wikipedia.org/wiki/Luck I would like to drill into people's heads - that "Luck" happening or not happening is not relevant in any way, shape or form when explaining why something happened. ie.. "TurboGenius won due to luck" or Grandpa got hit by lightning 2 times due to "bad luck". Anyone who doesn't agree is free to plug the word "luck" into any calculation where it would prove to have a value of some kind. 2+2=4 You will never see "If you're lucky - 2+2=4" or Luck + 2 = 4 or even Luck+4x=13 ?? Laughs "Luck" isn't a thing. It can't be used to explain why system "A" won or lost - or player "B" won or lost. The house never once declares "luck" in it's profits over players who come in to gamble... because there's no such thing. There is only math. It is a math game. Everything else in life is probability, not luck. Thanks for reading my rant - it's always bothered me, always will - and people will continue to say "Good luck" without even understanding that it means nothing at all.
