DC9 was made of different materials from the 737 and so has a different lifespan.

They're of similar construction, and it's categorically false that the 737 classic had a maximum 20 year lifespan or they're living on borrowed time after that.
They're routinely operated as cargo aircraft in the United States, just like many other older jet aircraft (for reasons of operating economics, not safety)
Quite normal for passenger jets to last over 20 years, Northwest was flying 40 year old DC-9s in the US not that long ago, and the reason for retiring them is that their lower efficiency means they're worth less than the cost of the necessary overhauls, not that the maintenance can't be done.
