You Must Stretch

I pulled a muscle. My heart is killing me. I guess I'm not going to be able to use it for awhile. I dont' know exactly what happened. I think it was all the vacillating. I left a situation prematurely and then I tried to re-engage and next thing you know, ouch! I'm not as young as I used to be and I can't just particpate in activities without stretching first.
