Bob Mortimer has said that his health issues are now "dominating [his] life", revealing that they had forced him to give up a passion of his.
Over the years, the comedian has experienced a number of health scares, including needing triple heart bypass surgery in 2015.
More recently, he was admitted to hospital in September, with him saying at the time that he wasn't "very healthy," though a rep later said that he was doing fine.
Appearing on Channel 4's Sunday Brunch at the weekend, the comedian spoke about his health to presenters Tim Lovejoy and Simon Rimmer.
The update came when he was asked about pal Paul Whitehouse, 64. Bob has appeared alongside Paul on BBC series Mortimer & Whitehouse: Gone Fishing since 2018.
Asked about their health, specifically their hearts, Bob said: "They're doing fine." He added: "When you get to my age, it's your joints that go. That's what dominates your life".
He cited knees and elbows as examples, before revealing that he's had to give up a passion of his because of such issues. He shared: "I used to love preparing an exterior of a property ready to paint, but I can't do that anymore".

He suggested on the show that doing so would cause issues with his shoulders. He gestured that he can't move his arms and shoulders like he could when he was younger.
Bob - known for work with his comedy partner Vic Reeves, 63 - added: "You have a few operations". He further commented that such procedures "keep you ticking over."
He appeared on the show to promote his book The Satsuma Complex, which was released last month. An audiobook, narrated by Bob, has also been released recently.
Bob described the book as a "boy meets girl" story, though teased there is a "bit of a thriller element" too. He said he has tried to incorporate comedy into the project.
Sunday Brunch airs Sunday mornings on Channel 4 from 9.30am. You can catch up on recent episodes of the show through the broadcaster's streaming platform All4.
