Stress is not a useful term or easy to understand, because it is such a highly subjective phenomenon that it defies definition. And if you can’t define stress, how can you possibly measure it in your health?
Stress is difficult to talk about because it is so different for each of us. A good example is afforded by observing passengers on a steep roller coaster ride. Some are hunched down in the back seats, eyes shut, jaws clenched and white knuckled with an iron grip on the retaining bar. They can’t wait for the ride in the torture chamber to end so they can get back on solid ground and scamper away. But up front are the wide-eyed thrill seekers, yelling and relishing each steep plunge who race to get on the very next ride. Then in between you may find a few with an air of who cares that borders on boredom. So, was the roller coaster ride stressful?
