Have you ever been in a situation in which you get a little tense? Your heart might race a little? Maybe even sweat from the brow? Whether it's due to a time crunch at work or the number of tasks or chores you have at home that need to be finished by tomorrow, this feeling you have is known as stress. Normally being stressed can elicit a physical or mental response, sometimes both at the same time. Stress is rather common and most of us experience it at least once a day, but did you know that you can experience good AND bad stress?
