You are 26, you just finished med school and swore the Hippocratic oath yesterday. You woke up to see a blue police box sitting in your apartment and a guy with bowtie and fez looking in the mirror, he's talking to you, "Good, you're up, I need a new assistant. You're a doctor, so am I! I travel through time and do what I want, wanna come?" You think you are hallucinating, but still, do you stay or do you go?
