Stress Stress is often called a 21st century illness, but it has always been with us. These days we regard stress as a necessary evil of modern living. Yet stress is not altogether negative, and without it we would not enjoy some of the highpoints in life such as the anticipation before a date or the tension leading up to an important match. As a matter of fact, all these situations produce stress but if you manage to control it, you will feel stimulated. However, unlike these situations, which are generally positive and easier to deal with, sitting in a train that is running late, being stuck in a traffic jam or working to a tight deadline are much harder to control, and are therefore very likely to trigger off a significant amount of stress.
