It’s important to remember that evolution doesn’t care whether we are happy individuals or not. Nor whether we are relaxed. It’s about survival and keeping the species going. To our ancestors, heights were a real danger, because they only came in the form of cliffs; spoiled food could be contaminated; it was risky to offend murderous strangers; you didn’t want to cross an open field where lions could see you, and you might avoid starving to death by saving some food for the winter. Our ancestors survived thanks to their neurosis. They survived because of their anxieties. Those who weren’t anxious enough thousands of years ago simply didn’t survive.
Today, we have the same responses, but they are triggered by mostly psychological events. We get stressed because of traffic jams, deadlines at work or money worries. Nevertheless, our body’s response to stress has remained the same. Our heart pounds away and we become jumpy because of the stress chemicals released into our body.
