Always the daredevil, you accelerate your pedaling as you speed towards the open grave. At the last moment you try to launch your bicycle into the air, using the mound of dirt as a makeshift ramp.
Your bicycle touchs down and lands safely on the other side of the grave. You, unfortunately, do not. As you fall, you notice that the grave is much deeper than six feet. You fall for at least ten seconds before you plunge deep into some water.
You are underwater. You see a dim light deeper underwater. Do you:
Try to swim to the surface?
Dive deeper, toward the light source?
