Interesting equation! Human = Pig

\1. Human = eat + sleep + work + play,\ Pig = eat + sleep,\ Substitute: Human = Pig + work + play,\ That is: Human - play = Pig + work.\ Conclusion: People who don't know how to play = pigs who can work.\2. Man = eat + sleep + earn money,\ Pig = eat + sleep,\ Substitute: Man = Pig + earn money,\ That is: Pig = Man - earn money,\ So a man who doesn't earn money equals a pig.\3. Woman = eat + sleep + spend money,\ Pig = eat + sleep,\ Substitute: Woman = Pig + spend money,\ That is: Woman - spend money = Pig.\ Conclusion: Women who don't spend money are pigs.\In summary:\Men earn money so that women do not turn into pigs!\Women spend money so that men do not turn into pigs!\Conclusion:\Men + Women\= (Pig + earn money) + (Pig + spend money)\= Two pigs!!!
