Yeah, for sure. So we will try to do a good job working you up for everything that we think it may be. And right now, it sounds like it could be pulmonary fibrosis either like you know an autoimmune process or triggered after like an infection that you may have had in the past. We will definitely also look into see if it's perhaps a lung cancer, asthma and you mentioned you don't smoke so we don't think it could be COPD but we'll also test for that in case all everything else comes back negative.
