Comfortable retirement a fading dream for many

(06-15) 17:35 PDT -- Ruth Britton enjoys her part-time work as a college instructor. But, at 69, there are plenty of other things the Greenbrae resident would like to do - volunteer, write, take classes, travel.

The problem is, with the cost of living rising and the value of her investments falling, Britton can't do without the money she gets from teaching. She's already put off retirement several years. Now, she says she may have to stay on the job four or five years more.
