"I'm not sure how aware of the rest of the world I am. I live a rather sheltered existence"

Julian Clary's quote suggests that he is not well-informed about the world outside of his own life. He indicates that he lives a sheltered life, which might imply that he is not exposed to the exact same experiences as other individuals. This might be due to his own personal choices, or it might be since of his environment. It could likewise be a mix of both. His quote implies that he is not as familiar with the world as he could be, which he is not as notified as he could be. This might be due to an absence of access to details, or it might be due to the fact that he chooses to stay protected from the outdoors world. Whatever the factor, it is clear that Julian Clary is not as aware of the world as he might be.
