Muscle cramp

I was using computer the other night, and suddenly my muscle in my neck cramped. It caused me neck pain for almost 2 nights and I am still in pain. Therefore, I asked my professor for help and he prescribed me Arcoxia as pain killer and Norflex for relaxing my muscle. The muscle cramp hurt my neck a lot!!!

Anyway, my brother told me there was a case that happened in a train station (and that was real). A patient was chopped off into half by a train and another patient has broken her arm, foot, ribs and the head swallowed like a ball. But at that moment, the doctor only had 1 shot of morphine, so he could only apply it to one patient. The patient who was chopped into half, was still alive, but for sure he would die. So if you were the doctor, who would you apply the morphine to?

My brother chose the patient with broken arms and legs and I chose the one who was chopped of into half. Well, either answer is correct.

*The doctor in that case (the professor of my brother), he chose the one who was chopped into half. The reasoning is medicine is not only saving people, but also concerning patients who are in the end of their lives.
