Rock 'n' roll officially became the domain of senior citizens several years ago when the likes of Paul McCartney, Mick Jagger and Tina Turner reached retirement age.

Now it's time for heavy metal to get elderly.

Black Sabbath original members Ozzy Osbourne (vocals), Tony Iommi (guitar) and Bill Ward (drums) turn 65 in 2013.

Alice Cooper does, too.

Same for Robert Plant.

It must be surreal for people like my parents, who as a teenage couple in the early 1970s, were gleefully terrified at concerts by the scary young men of Sabbath and the Alice Cooper group.

For me, it's more sad than strange that my all-time favorite rock music still predates my birth.

I would love for a new rock band to come along and blow my mind the way Led Zeppelin did when my 12-year-old self discovered the group's second album among Dad's collection of vinyl.

But it just isn't happening.

My favorite new rock song of 2012?

A single called "Doom and Gloom" by a bunch of geriatrics calling themselves The Rolling Stones.

Anyway, here are some of the rockers turning 65 in 2013.

Alice Cooper (Feb. 4): It must be strange to sing "School's Out" and "I'm Eighteen" in concert the same day the social security check arrives but, hey, they're still great rock songs.

Steven Tyler (March 26): "Walk This Way" might soon take on a whole new meaning but not as long as Aerosmith keeps rocking like they did at a recent show in Tampa.

Steve Winwood (May 12): Seems like he's been around forever, right? That's because the "Roll with It" singer co-wrote and sang lead on the Spencer Davis Group's mid-1960s hit "Gimme Some Lovin'" when he was about 17.

Stevie Nicks (May 26): She's rock 'n' roll's most powerful witch and will live forever. That's a fact.

Robert Plant (Aug. 20): Yeah, he looked a bit like the Cowardly Lion at the recent Kennedy Center Honors but still sounds like a Golden God on the new Led Zeppelin reunion CD/DVD "Celebration Day," recorded in 2007.

Glenn Frey (Nov. 6): The "New Kid in Town" better "Take It Easy." Sorry, couldn't resist.

Ozzy Osbourne (Dec. 3): Time to switch from "Sweet Leaf" to sweet tea, there, Iron Man.

Ted Nugent (Dec. 13): Rock's most famous ant-drug and anti-alcohol advocate probably has a long life ahead of him: unless, of course, the next animal he aims to kill fights back and wins.
