As the first members of the baby boomer generation begin to enter retirement age, many are choosing to stay active. Though they are pushing 65, many older adults do not feel the need to enter into retirement, and are instead fighting the signs and societal constraints of aging, the Calgary Herald reports.

Among the older adults who are eschewing a standard retirement plan is 63-year-old Shirley Keetbaas. Despite her age, she actively volunteers at a local food bank, helping her husband run their company and traveling through Canada to play on an over-60 slow pitch softball team.

According to Jim Carter, president of the Canadian Marketing Association's Calgary chapter, those who wish to stay active in their communities are more likely to seek plastic surgery in an effort to help themselves look as young as they feel.

"They say 50 is the new 40 - and that's a boomer statement," he told the news source. "You didn't see this with our parents' generation. The technology wasn't there, but it was the boomers that created the technology."

In the United States, analysts are expecting a sharp rise in the number of senior citizens in the coming years. According to the Administration on Aging, there will be around 72 million people over the age of 65 by 2030.
