Tungsten will burn in an oxygen atmosphere, therefore standard light bulbs actually use an inert gas (like argon). The gas pressure slows down tungsten evaporation and prevents oxidation. The main reason for short living of the bulbs is that the filament gradually evaporating over time until it thins out and snaps.
