What do senior citizen music superstars like Paul McCartney, Bruce Springsteen, and Mick Jagger have in common? Sure, they share fame, fortune, and talent, but one of their most exciting mutual traits is their commitment to growing older with creativity and stamina. Still bringing down the house in their senior years and loved by fans of all ages, these legends prove that age truly is just a number.

Paul McCartney. Now 69 years old, the former Beatle and founder of Wings recently received the Gershwin Award in Music, which was presented to him at the White House by President Obama. The award is given to a composer for a lifetime of achievement in the music. He is still playing to packed concerts all over the world.

Bruce Springsteen. He's as much “The Boss” as ever. In 2009, he performed at the halftime show of Super Bowl XLII, wowing kids and longtime fans. That same year, he was named one of eight “Artists of the Decade” by Rolling Stone Magazine. In the past 10 years, Springsteen and his E Street Band have enjoyed a creative and commercial renaissance.

Mick Jagger. At the age of 68, he's still sexy, still dangerous. In 2007, The Rolling Stones made the Guinness Book of World Records for the success of their “A Bigger Bang” tour. Jagger recently started a new band, SuperHeavy, featuring acclaimed younger musicians Damian Marley, Joss Stone and others.

These senior rockers have defined what it means to age with style, providing inspiration to older adults all over the world. They don’t plan to slow down anytime soon, and neither should you. Rock on!
