Zebras have very real threats but don’t get ulcers because that stress-response episode is here and gone in seconds. But we humans—we highly intelligent, top-of-the-food-chain, we-can-put-one-of-us-on-the-moon humans—invent things to make us feel threatened. Antelopes don’t do that. They don’t lie awake at night, wondering if another antelope is going to make them transfer to another location or maybe fire them. That’s us. We do that. An antelope doesn’t lose sleep worrying it might have run up credit-card charges that it can’t pay off. We do.
