BAKERSFIELD, Calif. -- Researchers in Denmark brought together current research on life expectancy and quality of life in old age and found that we can expect the coming generations not only to live longer, but with less disability and greater levels of health going into old age.

Over the course of the 20th century, life expectancy in wealthier nations has increased by as much as 30 years.

New research has shown that even if the current health conditions stay the same, three quarters of babies born today can expect to see their 75th birthday.

If life expectancy continues to increase at its current rate, infants born today will have a 50 percent chance of making it to their 100th birthday. In contrast, those born in 1930 only had a 50 percent chance of living to see their 77th birthday.

While the growing elderly population may pose new financial burdens, researchers noted that with rising generations staying healthier longer, those in their 60s and early 70s may choose to retire later or to continue working part-time, which could lessen the load of these financial issues.
