People love Michael J. Fox.

He is one of the world’s most adored and revered actors, thanks to his iconic portrayal of Marty McFly in the Back to the Future trilogy and his amazing efforts in raising money for Parkinson’s research.

Although the 61-year-old actor frequently expressed optimism after his Parkinson’s diagnosis, he is also open about its toll on his health and well-being.

Fox claimed in an interview with Jane Pauley of CBS Sunday Morning that while he has made the most of his life despite the diagnosis, Parkinson’s disease is now “banging on the door.”

The retiring actor declared, “It’s getting harder. Every day it gets harder. But that’s just how things are. Who should I talk to about that, you know?”

He said a tumor was discovered on his spine, leading to recent spinal surgery. It was harmless, but it made it difficult for him to walk and caused an injury when he fell: “[I] broke this arm, and I split this arm, and I broke this elbow. My face was broken. Fox said to Pauley.

Along with pneumonia and food aspiration, falling is a “big killer” for Parkinson’s patients, according to the Back to the Future actor.
