Every day someone's shutter fails, it can fail at any time regardless of factory specification, but that doesn't mean you should worry about it. When it fails and if it fails just get a service to put a new one in, a lot cheaper than buying a new camera.
If you shoot critical events you should always have a backup.
Maybe the shutter will last long enough so that your camera will become obsolete to you and you won't bother changing it and just get a new camera and thrash the old one.
If you think that shutter change service is expensive you should rethink your camera probably.
That's all to it, shoot until you kill it, change it, continue shooting.
