Micheal J. Fox heartbreaking update on Parkinson’s battle as he predicts what age he’ll die

MICHAEL J. Fox fears he won't make it to his 80th birthday as his Parkinson’s battle worsens.

The Back to the Future actor, 61, has spent his life raising awareness of the disease after his diagnosis at 29.

In a new interview with CBS Sunday Morning, Michael admitted: "I've been thinking about the mortality of it… I’m not gonna be 80."

He added: “I’m not going to lie, it's getting hard, it's getting harder.

"Every day is tougher. But, but that's — that's the way it is."

Michael is best known for starring alongside Christopher Lloyd in Back To The Future when he shot to fame as an 80s teen heartthrob.

After his diagnosis, he set up the Michael J. Fox Foundation to improve the lives of others at risk of the disease.

He says his team are devising new ways to detect and treat Parkinson’s.

“The idea of a biomarker… a way to identify the disease before the disease is present," Michael explains.

“By the time I was diagnosed, I had a little twitch in my pinky but...with this, we can identify the disease really early and help progression and essentially cure ahead of the game."

The NHS states there are three main signs of the condition: Involuntary shaking of particular parts of the body, known as tremors, slow movement and stiff and inflexible muscles.

Guidance states that a person with the condition might also experience a wide range of other physical and psychological symptoms.

This could include depression and anxiety as well as balance problems, which the NHS states might increase your chances of a fall.

Other signs might include a loss of smell, problems sleeping or memory issues.
