Don't want to pry. Just say no comment if the questions are too personal.
When I hear stories like this I would typically ask if she saved for retirement, had a pension, relied mostly on social security being there or maybe didn't earn enough to allow putting something away for retirement. Some folks, including me, were never given lessons on finance. My dad lost his job several times when I was growing up. The family also had some medical setbacks. So I know things can happen to knock people's plans off track, too. However, it is good to explore and discuss these historical, documented situations to help young people realize that they need to learn about finances and what can happen if you don't plan to live to be 100 and you actually do live to be 100.
Just as an example if you put a $1,000,000.00 in the bank and the bank is currently only paying 1% interest, you will only get ten thousand dollars a year in interest. If you are currently making $50,000.00 per year and are used to living on that, you are going to have to dig into your savings to the tune of $40,000.00 a year just to maintain your lifestyle and that's not taking inflation into account. So you retire at 60 with a million bucks, suck 40K out each year and in 25 years when you are 85 your money is ALL GONE! You got 15 years left to live and no money.
Of course, that scenario leaves out lots of variables, like interest up and down, rate of inflation, social security supplement, less expenses for commuting to work, etc... but you get the drift. A million dollar nest egg earning low interest in the bank might not be enough to maintain a comfortable living for 25 years of retirement.
