has been standing for 4 months. About a month ago noticed that my diaphragm has, for the lack of better word, &quot;got straightened&quot;. Sitting, probably very incorrect, for 36 years - since the first grade in school - i always thought that it is just my body construction that i have that difficulty breathing full lungs while swimming or running. Lower back also feels better where it matters. And you can&#x27;t really move while sitting whereis standing you do move a bit - like walking back and forward while waiting for that beast to rebuild.
