If you have ever procrastinated and then found yourself energized to complete a task at the last minute, then you have used the beneficial aspect of the fight or flight response (not the procrastinating part, but the energizing part). You see, with all its negative long term effects, the fight or flight response still gives us energy, and if we know how to use that energy, then stress is potentially good, at least in the short term.
