41. Jack Osbourne
Jack Osbourne, son of Sharon and Ozzy Osbourne, was diagnosed with multiple sclerosis at just 26 years old in 2012. The first sign was when this former reality TV star lost vision in his right eye, and several specialist trips followed this before making the diagnosis. When discovering his condition, Jack says he felt a strange obligation to share this news with people. He thought it could benefit others if this condition were discussed more. According to Jack, it’s not a one size fits all diagnosis or treatment, and you must find what works for you to manage this condition.
