This analogy came to mind yesterday. When you're recovering and you get to that point where your muscles start to fail and you can't go any further, this is like a brown out where there is too much demand on existing power lines (nerves) and your power starts to shut down. If you continue it becomes a black out situation where you collapse because there is no power left to give. If the system rests power is restored.
