There's a very steep mental decline after 56 in this job, and they want you to get at least 20 yrs of service in.Why the age limit discrimination tho?
There's a mandatory retirement age of 56 (but you can retire at 50), but you get a 6 figure pension along with however much in your TSP.
Not uncommon people end up with $4mil + from retirement savings plus their yearly 6 figure pension.
