Tina Turner will turn 69 next month. What's a grandmother to do? After an eight-year retirement from the stage, the rock 'n' soul wonder woman is strutting her stuff for two hours a night this fall.

How does she do it? "I have no secret," Tina told People magazine. "I have good genes. But I get a lot of sleep and eat healthy. I was never into drugs or smoking. I have an occasional glass of wine or champagne, but that's about it."

To prepare for her tour, Tina and her "girls" danced eight to 10 hours a day. Obviously, she -- and her career -- have legs, but lots of other parts have helped to create an extraordinary body of work.

MIND

When Anna Mae Bullock put on her wig, she became Tina Turner. Maybe she, like Samson, gained strength from her "hair."

WIG

Nothing was evah nice and easy for her. But she eventually worked things out through the Buddhist faith she developed in the mid-1970s.

MOUTH

Dripping with rural, Southern-fried soul, her loud, leathery voice makes every song her own -- even all those hits written by men.

HEART

Heartbreak and hardship have fueled her biggest songs. But you might as well face it, she's addicted to music.

ARMS

For two decades, she worked for her man (Ike) every night and day. And she lost plenty of sleep. Eventually, she summoned the strength to say, "You'd better be good to me."

LEGS

Simply the best. Better than all the rest. Onstage, she becomes Tina Tornado, a force of nature who taught Mick Jagger how to move and women how to walk away.
