(NBC News) A recent Pew Research Center report found nearly half the country's 65-to-75-year-olds are still working, putting off full-time retirement.
Now a Bankrate.com survey suggests the numbers may go even higher.
"We found a big spike from our last survey in the number of people who would like to work for as long as possible for both reasons, both because they like to work and because the money is great to have," says Bankrate's Jill Cornfield.
Bankrate's survey of a thousand American adults found seven in ten plan to keep working during retirement, many because they have to.
"We have longer and longer life expectancies," Cornfield notes. "We have a harder and harder time saving for retirement, many of us don't have pensions."
Still, Cornfield, Bankrate's retirement specialist, says the surprising find in the survey was how many plan to keep working only because they want to.
"It brings more than just money and something to do everyday, it brings engagement, it keeps your mind sharp. It gives you a social network," she explains.
