Michael J. Fox, the beloved actor who shot to fame as Marty McFly, has been candid about living with Parkinson’s disease. At 60, he admits that acting is becoming harder—memorizing lines and performing lengthy scenes no longer comes as easily. Roles with heavy dialogue are increasingly challenging, and he now avoids them when possible.

Despite the obstacles, Fox remains resilient. He has undergone spinal cord surgery and intensive physical therapy, yet continues to stay active and positive. He channels his energy into the Michael J. Fox Foundation, which has raised over $1 billion for Parkinson’s research. “Optimism comes from finding something to be grateful for,” he says.

Fox has also faced public scrutiny, from internet trolls to the physical challenges of Parkinson’s. Yet his family, especially his children, keep him grounded and laughing. Even with the disease, he treasures life, his wife, and children, calling Parkinson’s “a gift that keeps on giving.”

Reunions with his Back to the Future co-star Christopher Lloyd remind fans of the magic he brought to the screen, and his legacy—as an actor and an advocate—remains inspiring.
