Well, if the shutter count reaches 100,000 and you still have the camera I would say that you are probably pretty fond of it. If it does quit working then it has certainly earned a bit of repair. Get it fixed and start shooting again. An estimated lifespan is just that, an estimate. You may never have a problem with it.
Also, consider sending it to Nikon once a year if you use it a lot. they'll clean and adjust for a reasonable price.
