The Back to the Future star started displaying symptoms of the long-term degenerative disorder, which affects the central nervous system, in 1991, and was diagnosed with the disease the following year (92).

Michael manages his Parkinson's disease with medication, but still struggles with shaking, rigidity and slowness of movement. However, in a new interview the actor insisted that making light of his health issues really helps to improve his outlook.

"The truth is that on most days, there comes a point where I literally can't stop laughing at my own symptoms," he told AARP The Magazine.

For instance, the 55-year-old shared that he often finds it hilarious when he struggles to make a cup of coffee for his wife Tracy Pollan.

"I pour a cup - a little trouble there. Then I put both hands around the cup," he said. "She's watching. 'Can I get that for you, dear?' 'Nah, I got it!' Then I begin this trek across the kitchen. It starts off bad. Only gets worse. Hot java's sloshing onto my hands, onto the floor.

"But the thing that makes it hilarious to me is when I think of someone else watching all this and thinking, 'Poor Michael can't even get the coffee - it's so sad!'"

Michael also explained that the most difficult aspect of battling the disease is dealing with other people's preconceived notions of the condition. But he claimed that the actual symptoms of the disease aren't particularly painful.

"The only real pain I get is in my feet, which sometimes shuffle and curl up in cramps when I'm sleeping," he said. "Which is why I keep a very stiff pair of shoes on the floor next to my bed."
