NEW YORK, NY.- David Lynch, co-creator of the groundbreaking series “Twin Peaks” and director of “Mulholland Drive” and “Blue Velvet,” said Monday that he had emphysema but that he would not retire.

Lynch, 78, confirmed the diagnosis in a social media post after revealing it in an interview featured in the September issue of Sight and Sound, a monthly film magazine by the British Film Institute. He added that his mobility was limited and that he could continue directing only remotely.

After the interview was quoted in several publications, Lynch said in a social post that he had no plans to retire.

“Yes, I have emphysema from my many years of smoking. I have to say that I enjoyed smoking very much, and I do love tobacco - the smell of it, lighting cigarettes on fire, smoking them - but there is a price to pay for this enjoyment, and the price for me is emphysema,” Lynch wrote in his post on social media.

Lynch said that he quit smoking more than two years ago, and that recent tests showed he was “in excellent shape except for emphysema.”

“I am filled with happiness, and I will never retire,” he said.

Lynch is perhaps best known for the television show “Twin Peaks,” an eerie mystery drama that was considered cutting-edge TV when it appeared on ABC in 1990. The show was adapted for the big screen in a film called “Twin Peaks: Fire Walk With Me” in 1992 and later revived in 2017 on Showtime.

Last year, Lynch made a cameo appearance as the character John Ford in Steven Spielberg’s “The Fabelmans,” a film about a family closely modeled on the Spielbergs. Lynch appears in the end of the movie, when he gives Sammy Fabelman, the main character, advice about filmmaking.

According to the American Lung Association, emphysema, also referred to as chronic obstructive lung disease, is a lung disease that causes shortness of breath. Smoking and air pollution are the most common causes. Early warning signs of the disease include coughing up mucus, wheezing and chest tightness, the ALA says on its website.
