this is a spirometry device we have been measuring lung health for quite some time my lungs were in fantastic condition when we first started measuring this and then when I got covered in November I had some pretty discouraging lung damage which was an eye-opener for me because I'd seen a lot of reports I didn't know what it'd have and what effect it'd have on me if I got it and so we've been trying to rebuild my lungs from that
