Time is always present; time will always be there, and it determines our lives. We cannot get back lost time. Time is a complex construct created by us humans, which we have agreed on worldwide and which we all have to live by. Time is a definition that describes events and indicates how large or small the distance between two events is. We all have the same amount of time, but it passes at different speeds for each of us. Everyone perceives it differently: we often have too little, rarely too much. Sometimes we fear it, sometimes it gives us hope. We exchange time for money. You could say that time is a true luxury.
