How to say "How are you" in Polish? 
Forget about "Jak się masz" (How are you?), because Poles almost never use this expression nowadays.
"Jak się masz?" doesn't sound natural to native speakers, though this expression exists in the Polish language (the most often in some textbooks for foreigners).
So I recommend to you to use some other more useful expressions instead of "Jak się masz?".
So what should you say after "hello" in Polish when you meet someone who you know?
