You are riding in a tiny elevator with an elderly gentleman. The elevator becomes stuck between floors and you can't get out. Hours pass. There is just enough room to lie down side by side. You fall asleep. When you wake up you find that the old man has died in his sleep. You can hear the sounds of rescue workers. A voice outside tells you that they are working but it will be hours until you are saved. You now have to go #2 badly. There is no way that you can hold it until you are rescued. What do you do and why?
