I'm catching up on posts . . . Physical activity . . . this morning! I have modified my exercise routine - "so I don't hurt myself" - ha! Telling my brain, "I will not stop." All of a sudden my back has acted up, a new pain; but, I'm not falling for it. Went to the gym and said to myself, "Nonsense. This new pain is out of the blue and ludicrous! You're not going to keep me from exercising." Still playing it safe, though. Don't want to stupidly dive in full speed and really hurt myself and have my brain think it won. I told my brain, "I will continue to increase what I do every day, in a reasonable manner. You can't stop me."
