Sorry, I guess that I must have missed some of the story.  Where exactly does it say that any of this story is "evidence based"?

As far as I can tell, a group of business experts have suggested that increasing the retirement age will help business, but we haven't heard from doctors, psychologists, physiologists, futurists or any other experts to actually create "evidence" with which to judge this issue.

Be careful when you play with big words that you don't understand.
