Rock stars lead notoriously fast-paced lives. The most successful of them routinely tour the world as they hop from one time zone to another. Fans will them to push themselves to their mental, physical and emotional extremes. All-night parties full of supermodels and millionaires where nothing is taboo and the only rule is to live for the moment. Few are known to lead sedate lives away from the public eye. In fact, many are as well known for their personal exploits as they are for their transcendent music. In a career spanning nearly fifty years, singer and songwriter Ozzy Osbourne has proven to be just such an individual.
