Simon Cowell says the idea of retirement makes him "want to jump off a bridge."
The 'Britain's Got Talent' and "X Factor' boss also claims that he has never had his heart broken and thinks most people's marriages are boring.
The 52-year-old star insists he isn't ready to retire and told the Telegraph newspaper: "I'd rather drop dead doing my job. The idea of getting up in the morning to play golf makes me want to jump off a bridge."
But Simon isn't worried about getting older because he believes there are advantages.
He explained: "You don't get so insecure or competitive. And if you can grow old gracefully, you're fit and healthy and not bad looking."
Simon - who called off his engagement to make-up artist Mezhgan Hussainy in early 2012 - was most recently linked to Carmen Electra and is still close to his ex-girlfriends Jackie Sinclair, Sinitta and Terri Seymour but doesn't think he will ever marry.
He said: "Well it worries me because I've seen it destroy people. And I couldn't think of anything worse than being in an unhappy marriage.
"Actually, being on my own is the best thing in the world. It's like breathing in oxygen -- I can really switch off then.
"I'm fine as I am. I think that when you get into a rut, it gets boring.
"Look, when no matter how big your house is, you are going to end up on the same sofa, in the same bed or in the same room as a person, you are going to get bored. It's a boring routine."
The music mogul hinted that he has never really been in love.
He said: "I have a different kind of love. The love I have for my ex-girlfriends will always be there, so I think that's true love. People confuse ego, lust, insecurity with true love. But for me, whether it's Jackie, Mezhgan, Sinitta or Terri, they will be in my life forever. I genuinely love them."
