"I was a carpenter before I was disabled with macular degeneration. That was 25 years ago. Ten years after the diagnosis, I joined the Tennessee Business Enterprises for the Blind, and now I operate the vending machines at the Federal Building and City Hall. The hardest part was when I first found out I was losing my vision. I had the diagnosis, but then the second doctor confirmed it. That was tough. I had spent twenty years learning the carpentry trade and it was my time to turn around and teach someone else, but I had to quit. I couldn't pass that knowledge on."
