My Back Went On Strike

I am not one of those sports crazy people who lives to exercise. I do it in hopes that it will help keep me in better shape and so that I can be fully functional in my old age. I don’t usually complain about it, I just do it.  
Well, today while working out with my trainer and my friend Christy I did something, what I don’t know, but it caused me to pull a muscle in my back. It wasn’t one of those, “oh my goodness, what did I just do?” moments. It was the, “now that I drove home why can’t I get out of the car?” pains. 
I took some pain killer and went about my day, mostly sitting, but things did not improve. I came home to lay down and decided that I was going to skip my two evening commitments. Is this what old age has come to?
Am I destined to only doing one thing a day and then need an afternoon nap to make it through the rest of the evening? Carter and Russ gave me a terrible birthday present of a weekend away to figure out what I am going to do with my life when Carter goes to college in 15 months. I was not worried about what I was going to do. Now I see that I am going to have to test drive scooters and look at ramps for our house.
I am sure that is a better sounding plan to Carter than my previously unannounced plan to buy an apartment in the city where she is going to college and have lunch with her everyday between my morning exercise and afternoon walk.  
All kidding aside. I think maybe this hurt back is just a way to give me a night off from the overload of May. Sorry I did not make my meetings tonight. My back went on strike and I choose not to cross its picket line. A huge dose of sleep/pain killer and a long sleep is what I look forward to.
