I think one advantage would be having enough money to do the things I want to do without having to worry if I have enough to pay the rent. The main disadvantage would be the absolute lack of privacy - I don't know if I could handle that!

the correct question is what ARE... be careful about it

The question should be 'what are the......? and not what is....?

If you are a celebrity like Justin Bieber you have no room for error. Everyone knows what he does, where he goes. With the Internet and social media any mistake is forever present. As for advantages, everybody wants your autograph. Everyone wants to do selfies with you. But you don't have privacy. And you must really verify who your true friends are. This is a very interesting topic !
