Retiring on a cruise ship? More Americans are making it a reality

A surge in retirements is sweeping America as baby boomers enter their golden years. More than 4 million people are poised to turn 65 this year, part of the largest wave of retirement-age Americans in history.

For some, retirement looks different than traditional options. Instead of settling into condos or retirement communities, they're choosing a life at sea.

"I live at sea and I'm retired," says Jo Johnston, who said she has been on "six or eight cruises of 80 days or longer."
