Sir Mick Jagger has insisted there is “nothing good” about getting older.

The 82-year-old Rolling Stones frontman lamented the fact he has “forgotten” the wisdom he has dispensed over the years and he is much less capable physically than he used to be.

Asked what is good and bad about getting older on The New York Times’ podcast The Interview, he said: “There’s nothing good about it. Nothing. You don’t get wisdom. You forget everything. Forgot all my wisdom.

“I might have had a couple of pearls, but I’ve forgotten what they are.

“It’s not particularly pleasant and, of course, you can’t do things as quickly as you want to, and physically you can’t do things that you would like to do. You can still do them, but you have to be more careful.”

The Satisfaction hitmaker admitted his decades of fame have left him “disassociated” from the world around him because his life is no longer “normal”.

He said: “Obviously, it’s not normal.

“It is not like most people’s lives. It does affect you. You can become disassociated. From other people.

“A lot of people in show business only hang around with people in show business, because they’ve got something in common, they can relate to each other, and you get disassociated from what people might call ‘real life’.”

But Sir Mick does his best to keep his feet on the ground.

Asked what he does to stay grounded, he replied: “You go out and walk on the street on your own and do normal things.”

But even that, he admitted, only offers temporary relief.

He continued: “Nevertheless, that’s only temporary because psychologically your actual state of mind is permanently damaged.”

The veteran rocker isn’t interested in getting political during Rolling Stones concerts because he just wants fans to have a good time and forget the stresses and strains of everyday life.

He explained:”The bottom line is that my job in the live music world is to ensure]people that come have the best time they possibly can, and for two hours forget all their problems and the problems of the world.

“Their mortgages and whatever. Just so they can have the best time.

“Your job is to make them go more apeshit. You don’t want to lecture them.”
