Do outsiders age?

[johnlocke90]

I can't find anything about it. Sure, some outsiders are known to not age(Gods and demon lords for instance), but on the other hand Tieflings age. I can't find anything on who does and doesn't die of old age.

Outsiders with the native subtype (like tieflings etc) definitely age and die eventually.

Other outsiders I think not, but it might be different from species to species

I was wondering if there was anything official on it. Particularly because I am interested in becoming an outsider(high level play)
