18. Mick Jagger (Born In 1943) – The Rolling Stones

More than 60 years after the Rolling Stones started out in London, Mick Jagger still runs across stadium stages like a man half his age. His strict fitness routine is the stuff of legend: running, dance training and a careful diet.

The band's 2023 album Hackney Diamonds was their first record of new songs in almost two decades, and the tour that followed filled stadiums across North America. Jagger has also become a great-grandfather, not that you'd guess it.
