Humans, says Edward M. Hallowell, have the ability to call up images of bad things that happened in the past and to anticipate future events. Combine these higher thought processes with our hardwired danger-detection systems, and you get a near-universal human phenomenon: worry.
That’s not necessarily a bad thing, says Hallowell. “When used properly, worry is an incredible device,” he says. After all, a little healthy worrying is okay if it leads to constructive action-like having a doctor look at that weird spot on your back.
Hallowell insists, though, that there’s a right way to worry. “Never do it alone, get the facts and then make a plan,” he says. Most of us have survived a recession, so we’re familiar with the belt. Tightening strategies needed to survive a stump.
Unfortunately, few of us have much experience dealing with the threat of terrorism, so it’s been difficult to get facts about how we should respond. That’s why hallowell belleves it was okay for people to indulge some extreme worries last fall by asking doctors for Cipro理学(抗炭疽菌的药物) and buying gas masks.
