Video: This super-fit 75-year-old great granddad puts his impressive physique down to 'hard graft' - and rock and roll dancing.

Buff Bill Jones might be well into his eighth decade but he still looks sprightly - thanks to his thick natural dark head of hair and bulging biceps.

He claims he can “out-dance anybody” and said: “I am still enjoying everything I used to enjoy as a young man. “When I was a kid, your grandparents were old at 40 but it doesn’t have to be like that anymore. It’s great.” The dad-of-nine said he has never gone mad at the gym and attributes his muscular body to years of working with heavy machinery.
