I spent 6 years living on The World, a cruise ship for millionaires. It was like the Four Seasons on steroids — readjusting to reality was tough.

• Retired lawyer Peter Antonucci lived on The World, a luxurious residential ship, for six years.
• It's extremely exclusive. The World's 165 condos cost between $2 million and $15 million each.
• Antonucci told BI that it was as luxurious as it gets, making adjusting back to the real world hard.

This as-told-to essay is based on a conversation with retired lawyer Peter Antonucci, who spent six years living on The World — a residential ship for millionaires. Antonucci has written three novels about scandals on the high seas.
