Is aging an issue or an advantage?

According to an article in the HR magazine "Keep pace with older workers"; older workers bring experience and research shows they are equally productive as young employees. Older workers have much lower turnover because of increased loyalty and stability and would be satisfied in their jobs.

Interesting statistics of a store suggests that turnover was six times less for workers over 50 than for those under 30. Further research shows no correlation between age and job performance.
Thus employers could make the work environment more pleasant to the aging workers by understanding their needs, providing them with essential training and helping them adapt to change.
By understanding aging, employers can make mature workers even more productive as well as simultaneously leverage upon their experience to build a legacy of their own.
