Simon Cowell has revealed he knows when he is going to die. The 55-year-old music mogul had undergone an advanced DNA test in Los Angeles which predicts the age people will die at.

Speaking to The Mirror, the X Factor boss said: "I had the DNA test done in LA which predicts when you're going to die. They take your blood and DNA, then give you back a sheet of paper which says 'We think you're going to be alive until xxxx'. Obviously it doesn't take account of the fact you might get hit by a bus tomorrow, but I got told I'd die aged 95 – which is about as good as you can expect."

Cowell credited New York socialite Lauren Silverman and their son, Eric for his life expectancy. He said: "I think a lot of it is down to having a family now, and a lack of stress. I've learned to deal with stress much better now, things don't bother me in the way that they once used to."

Cowell admitted that he undergoes regular health checks and claimed that despite his smoking habit, he is fit and fine.

"I'm a great believer in getting checked out because if you know you're OK, you actually feel better; your mind plays a big part of it. I get everything checked out twice a year and so far, considering everything I've done, I've been lucky and had no scares.

"My heart, my lungs, my blood – they've all been checked. I remember one of the doctors almost being disappointed when he showed me the results because he couldn't wait to tell me what smoking was doing to me. But there was nothing there," he explained.
