Imagine yourself driving your car when it suddenly begins to choke and shudder. At first, it’s only one system that breaks down, but then another and another follow. It’s not that the car has completely shut down.
The main systems, like the engine and the gear, are still running. But the lights go on and off intermittently, and every so often the car jerks to a halt. Then, miraculously, the failing engine restarts.
Yes, you’re still moving but the odds are not good that you’ll continue moving much longer. If this happened to you, what would you do?
