The 84-year-old singer - who lives on a Texas ranch with fourth wife Annie - insists he has no plans to hang up his guitar in the near future because he enjoys it, reported People magazine.
"What do you want me to quit? I just play music and a little golf and I don't wanna give up either one of those!" he says.
The musician is an advocate for the legalisation of cannabis and has no plans to quit the drug himself as it helps him to relax and "act like a grown-up".
