The Beatles legend - who is set to embark on a world tour later this year - has reportedly approached the Rolling Stones frontman for tips on surviving life on the road, now he is in his sixties.
A source revealed: "Paul is really good friends with Mick. Despite rumors of rivalry, they've been mates since they started out in the sixties."
"Mick has advised him to take a relaxing break before he embarks on the tour and then to try and factor one or two days more than usual between shows if possible. He said that it is the traveling that is the really tiring thing."
The Rolling Stones completed a two-year world tour in August last year, when Mick was 64.
Paul - who recently finalized his divorce from Heather Mills - turns 66 next month.
