Michael J. Fox has been an advocate for Parkinson's disease for over two decades following his diagnosis in 1991, when he was just 29 years old.

As the founder of the Michael J. Fox Foundation, an organization dedicated to finding a cure for the disease, Fox has helped doctors and researchers find a better understanding of how the disease progresses, and now he is revealing his own diagnosis could have come about because of something he did.

In a new interview, Fox was asked about a remark he made last November when receiving an honorary Oscar – Woody Harrelson had presented him with the award, and Fox said that the two of them had "done some damage" back in the '80s.

Specifically, he was asked if it was actually possible that he could have done some kind of damage that led to his Parkinson's diagnosis, and he answered, "Yeah, very possible."

MICHAEL J. FOX SAYS ‘I’M NOT GOING TO BE 80' AMID ONGOING BATTLE WITH PARKINSON'S DISEASE

"I mean, there's so many ways that you can ... that I could've hurt myself," he explained during an appearance on CBS Sunday Morning. "I could've hit my head. I could've drank too much at a certain developmental period."

He continued, "Most likely I think is that I was exposed to some kind of chemical. What we say is that genetics loads the gun and environment pulls the trigger."

Elsewhere in the interview, Fox said, "[Parkinson’s] banging on the door … I'm not going to lie, it's getting hard. It's getting harder. It's getting tougher. Every day it's tougher … that's the way it is. I mean, you know, who do I see about that?"

As the "Back to the Future" star suffers from the disease, he reflected on his perspective of mortality.

"You don't die from Parkinson's. You die with Parkinson's … I've been thinking about the mortality of it.… I'm not going to be 80. I'm not going to be 80." 

Fox continued to reveal how Parkinson’s has deeply impacted his life after a life-altering surgery.

"I had spinal surgery. I had a tumor on my spine … it was benign, but it messed up my walking … then, started to break stuff … broke this arm, and I broke this arm, I broke this elbow. I broke my face. I broke my hand," he said.

In addition to the interview, Fox wrote an opinion piece for USA Today titled, "Michael J. Fox: Do you have Parkinson's? New test is 'breakthrough' in diagnosing disease."

In his article, he wrote that "300 of the world’s top neuroscientists" are meeting this week in New York City, and that "The meeting’s focus has been electrified by one of the most significant Parkinson’s breakthroughs in decades, announced by PPMI [Parkinson's Progression Markers Iniative] and The Michael J. Fox Foundation just a few weeks ago: the discovery of a spinal fluid test that can objectively detect Parkinson’s in the cells of living people. It’s a first, and a monumental leap forward, for our disease."

He explained, "The new test is remarkably accurate (this is especially rare in brain disease). It will allow scientists to unlock some of Parkinson’s deepest-held secrets — like how early cellular dysfunction begins in brain and body cells, what other aspects of biology are involved in risk, onset and progression, and why Parkinson’s symptoms and disease course are so notoriously different in different people. This will crack wide open our ability to develop next-generation drugs that will benefit everyone living with the disease."

"What’s more, we can detect the insidious biology unfolding well before any outward symptoms have shown up. (Historically, symptoms have been the first discernible sign of the disease. In my case, it was an innocent-seeming flutter in my right pinky finger.) Not only will it be possible for the disease to be diagnosed and monitored earlier, but we are standing on the threshold of being able to prevent it altogether."

He concluded his piece by writing, "This breakthrough belongs to everyone who’s already taken part [in the research], and to those who will in the future. But thanks to these activated participants, it is already transforming what’s possible for us all."

Oregon lawmakers have advanced a sweeping bill intended to protect abortion and sex reassignment health care for transgender people by boosting legal safeguards and expanding access and insurance coverage.

Democratic representatives on Monday night passed the bill along party lines in a House floor vote that stretched for roughly six hours after Republicans sought to stall it.

Citing concerns about the wide-ranging scope of the bill — which addresses topics from minors’ access to abortion to emergency contraception at university student health centers to insurance coverage for sex reassignment care procedures — Republicans sought through various motions to send the bill back to different policy committees, delay the vote until next month and postpone it indefinitely.

Republican state Rep. Lily Morgan was among those who spoke in favor of its postponement.

MAINE BILL EXPANDING ABORTION ACCESS GETS ENOUGH CO-SPONSORS TO ENSURE PASSAGE

"It would give us the time to address some of the concerns brought up today, and if nothing else have an honest discussion around them," she said.

Republicans said they were frustrated that the bill, which has sparked fervent debate, only received one public hearing. The emotionally charged hearing at the state Capitol in Salem in March lasted several hours with dozens of people testifying in person. Hundreds more submitted written testimony both for and against it.

Democrats said the bill has been drafted over the past year and came out of a work group that was convened after the Supreme Court overturned the Roe v. Wade decision.

"This bill is the result of a year-long collaboration between dozens of legislators and stakeholders including patients, providers, advocates, community groups, and legal experts. It protects, strengthens, and expands safe, equitable access to reproductive and sex reassignment care—no matter who you are, where you live, or how much money you make," Democratic Speaker Dan Rayfield said in a news release.

The bill would implement a wide-ranging series of measures, including shielding patients and providers from lawsuits originating in states where abortion and sex reassignment care are now restricted. It would also require public universities and community colleges with student health centers to provide emergency contraception and medication abortion.

Additionally, it would expand insurance coverage for sex reassignment health care by barring insurers from defining as cosmetic procedures that are prescribed as medically necessary for treating gender dysphoria, among other things.

The parts of the proposal that have proved to be the most contentious have to do with minors. Under the legislation, doctors would be allowed to provide an abortion to anyone regardless of age, and it would bar them in certain cases from disclosing that to parents.

Democratic lawmakers have said such scenarios are rare. But critics said this could exclude parents from key aspects of their child’s health care.

Abortion remains legal at all stages of pregnancy in Oregon, and state law already bars health insurance companies from discriminating on the basis of gender identity. But Democratic lawmakers said the measure was needed to push back against the flurry of anti-abortion and anti-LGBTQ+ measures in conservative legislatures that is compelling people to travel to states like Oregon in search of such care.

The bill now heads to the state Senate, led also by Democrats, where it could be voted on as early as this week.
