BEGIN SCENARIO

8:00 am. You approach a bus stop on your way to work.

As you get closer, you notice an approximately 60–65-year-old man near the stop. He seems to be trying to say something, but you can't understand him. Suddenly, right in front of you, he appears to lose consciousness and collapses onto the pavement.

Other bystanders gather around him and attempt to ask him questions, but he does not respond. Some suggest reviving him by splashing water on his face. You see that the man is lying on his back, unresponsive, with his eyes closed and his skin turning blue.
