The question makes sense as we as humans will always be worried about something. If you don't have anything to worry, you will complain about the weather. Billionaires somehow found a way to waste their time worrying about really big problems. Their level of anxiety at first will be the same, but applied to bigger things. Others might take it as a game. It all depends of course. Some people get more anxious about facts, problems. Others about dealing with other people.
