Beth, the Mayo Clinic absolutely saved my life. I was in very bad shape when I started going there in 2013. In 2016, I was pre-qualified for a double lung transplant, I was able to avoid it by eliminating the massive infections I had going on. In 2013, I could not walk 10 feet without having to stop and sit and catch my breath. Going to a mall was out of the question, as was hiking and biking. Now, I walk and ride a bike indefinitely; provided the heat and humidity level isn't too bad. It was a long road to recovery, and it still takes diligence to stay well, but I did it. You can too!
