Thursday we did the staycation thing...and played tourist here at home. Went to Rock City, and I walked all the way through, got through fatman's and need of the eye just barely, but walked the stairs without issue. (i could not have done this even a year ago with post covid issues) Then to top it off we went to Chickamauga battlefield after and I went up wilders tower (136 steps) up and down again. These may all sound like small things, but if your lungs have been what mine went through this is amazing improvement.
