Is joining the Green Lantern Corps a death sentence?

Do any of the corps die of old age or peacefully?

Edit: Or retire?

If you are the type to retire, to lack the willpower to stick to the job until you are to decrepit to do so, then you lack the willpower to join in the first place.  As for old age or peacefully?  Yeah it happens, but don't kid yourself, the job is inherently dangerous.
