Ozzy Osbourne has no plans to retire

London: Rocker Ozzy Osbourne says he returned to his music career because he found retired life very boring.

"I tried that (retiring) and it was absolutely boring. You can`t go and say, `I`m retired now. That`s it!`. It won`t take long and you`re really gone for good and someone throws the last shovel of dirt on a coffin with your name on it. That`s the moment you`re really retiring - when you die," contactmusic.com quoted Osbourne, 61, as saying.

However, the heavy metal singer, who is currently on a world tour, admits this will be his last tour.

"This is going to be my last tour. I don`t want to be on the road for this long anymore. I have to stay in one place for a while, that`s why we`re taking a few breaks in between," he added.
