 I think more and more over the last years we've heard about that as patients become free to say, it's good, but. I recently saw a patient and I just bumped into her outside the hospital setting. I said, wow, you look great. How are things going? She said, well, a lot better than they were, but I still have a lot of problems. And they almost feel guilty sharing that with you because as they'll say, I'm one of the lucky ones. I got a transplant. So many people aren't able to.
