Sincere special thanks to all of you who have responded! I started my walking this morning. It's on a small scale, but it's a start. I live in the mountains/hills of North Georgia, so the ground isn't very level for any real serious walking... but my yard is fairly easy to navigate without horrible terrain. I just finished walking around the perimeter of my yard 8 times.... 3, 2, 2, 1 ---- and of course had to take breaks and I did have a bottle of water with me. It is something I CAN do to at least start the process. And I will do this 3, 2, 2, 1 for a week and then step it up slightly. I will do this twice a day... morning and late afternoon. It takes about 17 minutes each 8 time session........ so at least I am moving some.

Thanks for ALL your input. It will be a journey, but one I must travel if I expect to ever breathe well again.
