The Back-Stretching Exercises? Yeah, About That. ...

Oh, I don't know if I've yet to talk about going to physical rehab for my bad back.  It was killing me to the point where I had to go to a therapist about it.  The therapist gave me a few exercises to do; he says if I keep this up, the pain should be totally gone.

Have I done the exercises?  Nope.  Well, not really.  I've done them, sort of, and not as much as has been prescribed.  Just don't have the time.  And yes, my back is still killing me.

Now is around the time he has asked me to call him.  I'm afraid if I tell him the truth, he'll yell at me.  Which is further disincentive to call him.

I'm going to be a decrepit old man when I die, won't I?
