If you’re The Doctor, there’s no such thing as a quiet vacation. You can’t just TARDIS into a quiet little corner of time and space to relax. Something always goes wrong. Often it’s homicidal robots. Sometimes, it’s homicidal aliens. This time, it was a homicidal mummy that could only be seen by the intended victim. For not getting any time to relax, The Doctor doesn’t look too bad for 2,000 years old.
