Clunk, what year did you retire? You may find out that today's retirees are living longer than ever thanks to the miracles of modern medicine and healthier living.
My father started working in 1944.(no, he's not a pilot) He took an early retirement package at age 61 and has been living on a Defined Benefits pension now for 26 years. He is currently 87 and in perfect health.
In the future, we could have some retirees living to be 100 or more and being a drain on the pension plan. Letting pilots work past 60 will be one way to deal with this.
