Although Mick Jagger is rapidly approaching his 72nd birthday, The Rolling Stones singer doesn't see an end in sight quite yet. The frontman spoke with Rolling Stone recently in advance of his upcoming tour with the Stones and the band's Sticky Fingers reissue. Retirement isn't something he thinks about too often.

"I'm thinking about what the next tour is," he said. "I'm not thinking about retirement. I'm planning the next set of tours, so the answer is really, 'No, not really.'"

The group recently announced a 15-city trek through North America that's set to kick off May 24 in San Diego. They'll hit stadiums in Dallas, Atlanta and Detroit as well, so Jagger said he's been preparing physically for the tour.

"You have to prepare for what you're going to do. You don't prepare for running a marathon. You do start and stop stuff. You train for the quick burst. It's really hard to do the singing at the same time. I'll be doing cross-training and my trainer is going, 'Try and sing during this!' That's not really possible in a gym in front of other people," the singer added.

Jagger admitted to throwing around the idea of playing Sticky Fingers in its entirety at some of the shows, but that has yet to be finalized. He added that the band will at least play some deep cuts from the album like "Sister Morphine" and "Moonlight Mile."

While another Stones album might be out of the question, Jagger is all for recording a new release. If the band doesn't want to, then he said he'll try and put out a solo effort.

"I've got songs that would be great for the Stones, and I've got songs that wouldn't be perfect for the Stones," he said.
