Acting legend Brian Blessed is due to undergo heart surgery this week following a health scare which forced him to pull out of theatre production.
The Goldthorpe-born star, 78, collapsed while playing King Lear last month. In his first public appearance since, he revealed he was getting treatment abroad.
In an interview published in the Daily Mirror, he did not say where he was going but said his procedure would involve a “new invention from Germany”.
The Flash Gordon actor added: “They’ve promised it will make me feel like a 25-year-old for the next 30 years.
“I had severe fibrillation, but the reason is this old bugger has climbed Everest three times, walked across the North Pole, scaled mountains and volcanoes and trained as an astronaut.
“I’ve taken terrible risks, and I’ve put my heart under severe strain.
“But do you know what... my heart has been voted by Prince Phillip’s surgeons as the strongest they’ve seen in a man of my age.”
He joked: “I love life – there’s no such thing as death. I want to live until I’m 110.
“At the moment I’m a bit of out of breath, but once I’ve had the work done and have had a short break, I’ll be planning my next trip to Everest and a mission to Mars.”
