Yeah Mick takes really good care of himself. Of course this is a bit feedback loop thing. Because Mick has always worked the whole stage, that’s a thing he’s proud of. And of course they’re the Rolling Stones, they don’t play on small stages, they love those big wings and stuff. And if Mick is going to be all the way out on one wing for the 2nd verse and then get all the way to the same spot on the other wing during the guitar solo and still be able to sing the 3rd verse, Mick needs to be in shape. So one habit feeds the other.
Even Keith looks younger now than he did 5-10 years ago. He’s pretty much cleaned up his act since then.
