While most people his age are looking forward to retirement, the 61-year-old rocker is currently on tour promoting his new album Scream. At the peak of his Black Sabbath career, Ozzy was famed for his wild antics such as biting the head off a bat, but he insists he is starting to feel "old" and lives a far quieter lifestyle these days. He has calmed down so much, he even felt ridiculous driving the expensive sports car he bought recently, admitting that his 57-year-old wife Sharon felt equally silly sitting in the passenger seat. "I don`t drive that much but I thought, `I`m going to get a sports car`. Sharon hated the two-seater thing. `What the f**k am I thinking?` she said," Ozzy told the British TV show This Morning. The rocker went on to say he thinks an unfashionable three-wheel car would be more appropriate for him and his wife. "My days are long over, I should be having a three wheeler," he joked.
