Been a tough week so far. The temperature is 98 degrees. My knees are swollen and hurt like heck, and my left hip keeps going out on me. It is getting better, Working around the yard, and going up and downstairs at my daughters I think are taking it out on my knees. But, I'm not going to stop. I just need to heed the quote, "Don't let what you can't do, stop you from doing what you can do." I may just have to be careful doing what I can do. If that makes any sense.
