Today's session

I just received a resistance band today from my physical therapist.  I have also received a picture of exercises that I can use.  My back has its moment of pain.  I am also sore, so that could be why it has acted up somewhat.  I am in a state of relief as my muscles are not that tight.  I am concerned about the state of my health as it seems like I am physically falling apart.  I am 39 and I realize that I am nearing middle age as I am typing this, but I have wondered if I am too young for this.  It seems silly because we all age, but I do wonder about it, though the subject may seem too touchy even for me.  It was a 45 minute long session that I almost didn't feel like doing, but it was worth it.
