In English, it is usual to ask "How are you?" as a salutation. How can I say a similar thing in Italian?
Be careful, Italian "Come stai/sta?" is indeed asking about health or state of mind. Most likely, I would use it only if I know that something happened to the person in front of me. English usage of "how are you?" is closer to Italian "ciao", isn't it? "Come va?" could be ok, if it is told with a salutation tone, so to speak.
