Award-winning singer Linda Ronstadt told the AARP that she "can't sing a note" due to Parkinson's disease.
"I couldn’t sing," Ronstadt said, "and I couldn’t figure out why. I knew it was mechanical. I knew it had to do with the muscles, but I thought it might have also had something to do with the tick disease that I had. And it didn’t occur to me to go to a neurologist."
