Jackie Chan has reassured fans over the state of his health following concerns about his appearance.Photographs published earlier this year showed the actor looking much older than he had done previously, but in a post featuring a series of photos shared to mark his 70th birthday, he addressed fans’ concerns.Chan clarified that his appearance was actually part of his look for a role in a film. “Not so long ago, a lot of friends saw some recent photos of me on the internet, and they were all concerned about my health,” he wrote.“I want to take this opportunity to let everyone know, don’t worry! It’s just a character appearance for my latest movie.
