80 percent of retired Canadians consider themselves healthy according to an international survey.

In fact, they're at the top of the list of 10 countries surveyed.

The main reason for their excellent health is the high number of them who exercise regularly.

As Canada's population continues to age, physical exercise will continue to be very important in keeping health costs in check.

Too many baby boomers, however, haven't been working hard enough at establishing a healthy lifestyle that includes regular exercise.
