Lewis, who was in Los Angeles to promote a new Encore documentary on his long career in entertainment, said he still loved the television industry, but admitted some of its early luster had faded.
"No one rushes home anymore to watch something good," Lewis told his audience. "They rush home and hope they see something good."
The Los Angeles Times said Lewis also expressed some reservations about the isolation of social media. "We're not going to have human beings in 20 years; people don't know how to have conversations with each other," he said.
Otherwise, Lewis said, he feels good and has not been slowed down too much by his health. "I'm the happiest 85-year-old you'll ever see in your life," he said to what the Times called a "rapturous response."
