 Two months ago, I couldn't talk. He's part of a clinical trial at the Mayo Clinic, Dr. David Lott. My patients tell me, yeah, I may be alive, but I'm not really living.

One of the biggest critiques is that it's not a vital organ, but Lott says for people who can't breathe, swallow, or speak, it's life-changing. I'm Julie Walker.
