All seals will degrade with time and exposure to differential fluid, but your driving habits will have a significant impact on lifespan.
Can you drive with a rear pinion seal leak?
If you notice your differential has low fluid, chances are it is leaking from the pinion seal. This needs to be fixed in a timely manner because as the fluid levels drop, the gears will wear down as the friction increases. Without a proper working differential, your vehicle will not be able to be driven.
