That’s a bad analogy. If my brakes fail, once I come to a stop there’s no urgency in getting them fixed. I can abandon the care if it’s a lemon. I can have it towed home. I can use Yelp to find a reasonable mechanic. I can rent another car until this one’s fixed. It’s the opposite of “every second counts”. Meanwhile, this is the only heart I have, and if it’s in danger of stopping, I have approximately seconds to call 911 to get someone to come take me to the repair shop of their choosing.
