They're expecting it, because of all they've endured during the Great Recession and its wake—a retirement that might not be all that comfortable. And they're cutting back accordingly.

Boomers, according to a CBS Moneywatch report, have been feeling the pinch since the global financial crisis, and close to two thirds feel they personally have not thrived financially. The Bankers Life Center for a Secure Retirement study cited in the report finds that, among boomers who feel that way, more than half say that their savings are lower today than they were before the financial crisis.

The study also finds that boomers aren't just sitting still waiting for the roof to fall in; they're taking various actions to improve their financial situation—cutting spending and working on their portfolios. But it's too soon to tell whether what they're doing will be enough to see them through.
