for about 8 years (im 21), i constantly count words i hear or speak and the rule is when they are a multiple of 10 , i "win?" , and the reason its multiple of 10 is that i count them on my fingers , and i constantly do this , ive got the experience enough to guess to a good degree of accuracy how many words someone said without counting them and there are rules to this game , for ex. a word like "i'm" can be used as 2 words when needed and i must choose to use it as 1 or 2 words before completing the counting process , its not like a "word" its like a part , for ex , a word like happy can be 2 parts , a word like key is 1 part , its like how many times you start and stop or change the way you were talking , happy is 2 parts because its "ha pi"
