Michael J. Fox has opened up about his ongoing battle with Parkinson's - 30 years after his life-changing diagnosis.
The 60-year-old Back To The Future star was diagnosed when he was 29 years old. He was newly married to his wife, actress Tracy Pollan at the time.
"So very early in the marriage, she got this dumped on her. And the moment that I told her I was realizing was the last time we cried about it together. We haven't cried about Parkinson's since.
"We've just dealt with it and lived our lives. But we cried about it that first time," Fox told CBS Mornings.
Fox said he struggles with some of life's basic day-to-day functions, including going out to dinner with his family.
"I have a wheelchair that I use every now and then and it still sucks. I have a hard time getting to a restaurant and up the stairs to where my family's eating perhaps at a dinner. But then I'm there with my son and my three daughters and my wife, and friends of ours. And it's just like, that's great," he explained.
And while his diagnosis does come with its challenges, Fox admits he's fully aware of what he can control and what he can't.
"I thought, 'Who am I to tell people, cheer up? Who am I to tell people it's gonna be okay? Who am I to tell people 'Have a positive attitude," the actor said.
Elsewhere in the interview, Fox said living with Parkinson's is a "heavy thing" - however, he is determined to remain optimistic.
"And I really felt so much weight of that public persona being Mr. Optimist. And I still am Mr. Optimist. And I knew and in some small way, I knew in that moment, as dark as it was, that I would get back to that at some point," he said.
Fox first went public with his battle with the neurodegenerative disorder back in 1998.
In 2000, the actor launched the Michael J. Fox Foundation for Parkinson's research, which is "dedicated to finding a cure for Parkinson's disease through an aggressively funded research agenda and to ensuring the development of improved therapies for those living with Parkinson's today".
