Exhaustion

I am exhausted. I just worked 6 out of 8 days. I guess if you think about it taking a Monday to Monday the average Monday to Friday worker works 6 out of 8 days every week. The difference is (assuming a 40 hour work week) this scenario is 48 hours in 8 days. With the 12 hour shifts my career requires, I worked 72 hours in 8 days. Point being: I'm beat. (Disclaimer: numbers may be skewed as my math suffers when I'm tired. Which is not a good thing considering math is a big part of my career. And I spent the majority of the last 8 days at work. Tired.) My legs hurt. My feet are swollen. My mind is not functioning. My butt has been glued to my couch for the last two hours trying to recover. My train of thought has been completely lost at least 12 times during this post. What was I talking about? Too many numbers....
