     The number of women over 65 who are still working has increased by more than a third in the past ten

years. Do these women really like working? Women live longer than men, so they have to save more money

for their retired (退休的) lives. Women earn (挣) less, so they save less. And they work few years because

they have to look after children or elderly parents.

     How can we help women find a way to retire when they want to? Here are some thoughts:

     (1) Right now only 47% 0f working women take part in a company retirement plan. American business

can do much more to help that number grow.

     (2) Knowledge is power (力量). 53% 0f women who have a retirement plan said they would increase

their income (收入) if they had a chance to receive financial (财经的) education.

     (3) Non-working women can invest (投资) up to $5,000 every year to increase' their income.

     These ideas can help women work longer, not because they have to but because they want to.You can
