75 years old (Born on July 17, 1949)
Happy birthday, Geezer Butler! You're the only bassist who can claim you've survived Ozzy Osbourne's antics—not just once, but through decades of touring craziness. Your epic basslines on classics like "Paranoid," "Iron Man," and "War Pigs" laid down grooves that turned heavy metal into timeless magic (and for generations caused countless fans to air-bass in front of their mirrors).Recently, your autobiography reminded us all you're not only music legend but also storyteller-in-chief. Keep rocking hard and staying young at heart—we're pretty sure age doesn't apply when you're a living icon!
Have an incredible birthday—you're truly legendary!
