In ancient Egypt, Pharaoh's guards were pretty much always sealed in the pyramid (or tomb) with the pharaoh when he died. Sometimes they would be sacrificed so they would be dead when the tomb was sealed. It was believed that they would be with the pharaoh faster in the afterlife if they were already dead. Other times they would be left alive in the pyramid after it was sealed. We know this because of skeletons found in obscure places in pyramids. I guess the belief might have been that they could help ward off evil spirits that came to haunt the pharaoh after death. Odd stuff but what do you think? If you lived in ancient Egypt do you think you would "sign up" to be one of Pharaoh's guards knowing what would happen to you once he died? It would almost be your guaranteed fate unless you were to die before the pharaoh did.
