question: My brother has COPD, he is 42 years old and has the lungs of a 75 year old man according to his doctors. He takes breathing treatments every 4 hours, he has oxygen all over the place and uses as needed. He can't do anything without losing his breath. I want him to be able to enjoy life. I thought about donating one of my lungs to him. Would this be possible and would it help him?
