Like when is middle aged and venerable and such.
And what about all the other monsters in the Monster Manual?
Crothian said:Your Fey creatures are going to have long lifespans. Orcs, goblins, hobgoblins and kobolds and other smaller humaniods I would guess would be around human if not a little shorter. Animal life spans should be easy enough to look up. Magical beasts I think would have a life span about twice as long as the normal animal they are closest to. Oozes are anyone's guess.
Those are my thoughts, hope it helps.
