Are you saying people should retire just because they are old?
They both still sell out shows with fans who love them.
They apparently are still performing great shows.
Here are some reviews:

I especially liked this quote:
"Centuries from now, historians will stumble upon footage from a 2000s-era Rolling Stones concert and gape.
'How old are those dudes?” they’ll wonder, refusing to believe that a bunch of guys ranging from 68 to 74 years of age were capable of such visceral showmanship, such heartily performed songs, such unbelievable stamina.'"
They love to play.
Crowds love them.
It's fun.
This year I saw Fleetwood Mac -- 72-year-old Christine McVie and the rest of the band – ranging in age from 65 to 69 – were amazing. It was one of the best concerts I have seen in 40+ years of concert going.
73-year old Paul McCartney's shows are legendary for their quality and energy.
It's not as if these acts are embarrassing themselves, like old Elvis and Sinatra. Since these acts certainly have the money to retire and never lift a finger again (McCartney is worth over $1 billion, Jagger over $300 million, Diamond $175 million) they do it because they love it. Living in hotels and being on the road is hard work. It seems these acts love it and so do their fans. Good for them all.
