Here is the situation:
As you arrive at your friend's house one Saturday morning, you are surprised that your friend is not in his usual spot, in the driveway tinkering with the antique car he is currently restoring. It's a little chilly today though and you hear music coming from the garage, so you figure your friend is in the garage. When you open the garage door to say hello, you are not prepared to find your friend lying on the floor apparently unresponsive. What do you do??
