LOS ANGELES, Nov 4, (Agencies): Since publicly revealing his Parkinson's diagnosis in 1998, Michael J. Fox has remained open about his health challenges. In a recent interview, Fox candidly shared a series of medical setbacks he's faced in the past few years.

In his 2020 book, "No Time Like the Future," Fox recounted a pivotal moment in 2018 when a spinal tumor threatened to paralyze him. Following a successful surgery and months of physical therapy to regain his ability to walk, Fox faced another obstacle when he tripped in his apartment one night and broke his upper arm. He humorously recalls thinking, "I'm out of the lemonade business."

Subsequently, he experienced a cascade of medical mishaps, including breaking his other arm and shoulder, injuring his orbital bone and cheek, and dealing with a severe hand infection that almost led to its loss. Reflecting on these challenges, Fox remarked, "That was nothing."

Despite these health battles, Fox has surpassed the average life expectancy for Parkinson's patients, living 33 years since his diagnosis while the typical expectancy is 20. He remains unafraid of the future, acknowledging that one day he might "run out of gas" and decide not to face it, but he doesn't fear that day.

At 62 years old, Fox recognizes that his passing, while premature, wouldn't be unprecedented. What truly concerns him is anything that might jeopardize his family's well-being. He and his wife of 35 years, Tracy Pollan, have four children together: Sam (34), twin daughters Aquinnah and Schuyler (28), and daughter Esmé (22).

In a previous interview, Fox revealed the secret to the enduring success of his relationship with Pollan, emphasizing the importance of giving each other space to make mistakes and not misinterpreting slights. He described their marriage as a beautiful partnership.

With the time he has left, Fox remains dedicated to making a positive impact. Through his Michael J. Fox Foundation for Parkinson's Research, he has contributed almost $2 billion to research since its establishment in 2000. In April, research funded by the foundation was published in a neurology journal, showcasing a breakthrough in detecting Parkinson's in living individuals by identifying a specific biomarker protein.
