More Americans expect to work past their 65th birthdays and never retire, says a recent study. The Associated Press with the NORC Center for Public Affairs Research polled 1,075 people, age 50 and older. One-fourth of them said they never plan to retire. Among low-income earners in that age group that is even more true than for high earners. In America, the age of 65 is the traditional age to retire. Sixty percent of people aged 50 to 64 said they expect to work past their 65th birthday. More than half of those who are already older than 65 said they plan to keep working, too. They say they are working an average of 31 hours per week. Those 50 years of age or older said finances are the most important factor in the decision to when to retire.
