Good morning and thanks for the update. I am glad you are still feeling positive about you knees. Here's a possibility......have you ever done the "legs up the wall" Yoga pose. It sure helps my legs lose the stiff feeling. Let me know if you need a picture or two. You can also just put "legs up the wall" in the search block at the top of the page.....press on the spy glass and you will see all the mentions of that pose.

May you have contentment and ease.
Chris
