Every inhalation is under stress , prolonged and laboured , Everyexhalation is forced to go through mask . To protect our whole body against this corona virus from entering inside ,our lungs are paying the cost. Still nobody is talking about lungs...  We need to train them as we are imposing excessive burden on  those.
