Ozzy Osbourne admits he feels stronger and healthier than he has done in years.



The 69-year-old rocker has battled drink and drug addiction in the past but he's been sober for five years and is taking care of his body by exercising regularly.



Discussing his upcoming 70th birthday in December, he said: "It's only a number and I don't know how a 70-year-old person is supposed to act but I feel better at 70 than I did at 50.



At the height of his wild partying, the 'Paranoid' singer was convinced he'd be dead before the age of 40 - but once he neared that milestone, he was determined to live longer.
