The talk show host, 75, opened up about Mavis' "tricky" condition in a new chat with People on November 9. He noted how he's grateful that her illness is not as serious as cancer.
"I've been very lucky in my life. My wife is fighting dementia and all that, but it's not cancer. It's not a tumor, so I enjoy taking care of her," Jay explained.
He added he does not see caring for Mavis, 79, as a full-time job. "It's not work, because people come up, and say they feel so sorry. I understand the sympathy, because I know a lot of people are going through it, but it's okay," he went on.
"We have a good time. We have fun with it, and it is what it is," Jay shrugged.
