You sound like me because I need to do all those things to so I will feel better but have not so am out of shape, smoke to much, high blood pressure.
But when I had the walking pneumonia I was at home and smoked the whole time still and that was a killer. I smoked less but still I was doing what I should not of and I bet you could not smoke in the hospital.
Hope you can do all that you should and need to do. Plus look at all the money your save from not smoking.
