Lifespans of trees vary, depending on the species and variety. Other things, like disease and damage can also shorten a tree's life.
For most of the common spruces (Blue spruce, Norway spruce, White spruce), you can expect 150 - 200 year lifespan on average - though some have lived far longer - 800 or 900 years is not unheard of. There is even a documented case of a Norway Spruce that is thought to be 9,950 years old.
