Wanted: Personal Masseuse

I stayed late at work today, which is particularly brutal on a Monday and even more painful since I was up late watching (re:drinking) the Superbowl. My feet, my back...everything aches. I'm still not used to the physical demands of this job. I am always tired. I feel like a grandma when I'm ready for bed by 930pm and my roommates are just heading out for the night! Since I've started working, I'm much less active on weekends. This is partially due to the god awful weather, but also because I just want to relax and be off my feet for once. I wonder how I would ever be able to handle working the line in a restaurant where 12 hour days 5-6 days a week is pretty common. More importantly, do I even want to put my body through that?
