So what do you do when you're too old to Rock 'n' Roll but too young for the carpet slippers and pipe?
Well, you can try music management, the media or a respected career in academia.
But if you once played bass in the Rolling Stones, there really is only one obvious career choice: designing and marketing your own-brand metal detector.
In the roster of strange career moves for ex-rockers, Bill Wyman is out there in a field of his own, digging it up.
The man who quit the Stones in 1993 is now a leading light in the metal detectorist movement, designing and selling his own machines.
The Bill Wyman Signature Detector is a 'lightweight and adjustable implement and comes with a free informational DVD', according to the press release for this unlikely piece of rock 'n' roll merchandise.
"Metal detecting is not just for anoraks or eccentrics," says Bill.
"It's probably the best and the most enjoyable way of learning about our history.
"On any garden, country field, footpath, woodlands, beach or moorland, you can find a huge variety of historical objects, all easily located with this high quality metal detector."
And don't worry, the Bill Wyman Signature Detector comes with a money-back guarantee, just in case you can't get no satisfaction.
