You went to his office and saw this man. He said: “Hi, I waited you for a long time. I have a helicopter on the roof of this house, but first I need to save my wife.” You looked around and saw his wife in the cage. She already turned into a zombie, so there is no way to save her, you said. This man became very angry: “You don’t understand! She can be saved!!!” But you knew that only you have immunity to this virus. And now you understood, you need to sacrifice yourself to save her, but chance of it is less than 18%. This man stand up and started to go to you. Looks like he is becoming crazy. Suddenly his wife bit him. You stand in horror and think what to do while he becomes a zombie. What should you do? He will become the strongest.
