Pulmonary fibrosis is a rare lung disease that occurs when lung tissue becomes damaged and scarred, which makes it difficult for the lungs to work properly.

It can be caused by a multitude of factors, however, in most cases, the cause cannot be pinpointed, nor can the lung damage be repaired.

"My brother was very excited to see a lot of you create challenges for his latest released single Twerkaholic part 2 while he was in the ICU, it really brought him a big smile to his face," Denzil wrote.
