Life as a rich, famous or well know person could be quite lonely and very restricted. They cannot walk around any shopping centres without being noticed. Or go to cinema or have some fun in a pub or whatever la. For that matter, they may not have many friends or buddy to bond with.
That is why they need to fulfill some missing emotional needs.
If we want to, we can walk in to H81 and do it. Jack got to do it in his car or in his office or whatever. And cannot even go out makan with his GF. Here in SG, his face is in the adverts on TV and on taxis, no one in SG can miss his face.
