This is a graphical representation of my stress levels over the last three weeks. As you can see, stress levels nose dive from a moderate '5' during the week of the holiday, then soar to astronomical heights ('15' on my scale) afterwards.
What does this tell us?
a) Holidays make you stressed
b) Not being at work for a week makes you stressed
c) Too much time spent procrastinating and avoiding work after a holiday makes you stressed
