We all have it, to some degree, some more than others. To a certain extent, it is healthy; it keeps up sharp and in a life or death situation it will help us rise to the occasion. Some of us overeat when we experience it, and we tend not to indulge in what’s good for us either. Let’s face it, when was the last time you thought about a plate of vegetables after a bad day? We often don’t feel like ourselves, we might gain weight, lose sleep and some of us eventually end up sick: anything from a common cold to a serious disease. Left untreated, it can leave us susceptible to long term physical and psychological problems.
