How long do you think you'll live after retirement?

A recent study suggests many people, especially men, might be ill prepared for the years after retirement.

Researchers surveyed over 3,500 adults asking them how much longer would a 65-year-old person live in the U.S.

According to the survey, only a third of men gave the right answer -- 19 years.

Compared to 36% of women who say they're expected to live another 22 years.

The survey also showed that more men underestimated their lifespan when compared to women.

Experts say when it comes to retirement, to plan to live a longer life.
