He's 40, but former football star David Beckham says he still feels 21 in his heart and mind.

Beckham celebrated his 40th birthday with a break and a bash in Morocco earlier this year.

“It just felt like another birthday, to be honest. A little bit of a bigger birthday... I don't feel any different to when I turned 21. I still feel young at heart and in my head as well, and I think that's important,” Beckham told Prestige Hong Kong magazine, reports femalefirst.co.uk.

Beckham retired from his sporting career in 2013 and now his life revolves around being a stay-at-home father to his children, sons Brooklyn, 16, Romeo, 13, Cruz, 10, and four-year-old daughter Harper, while his wife Victoria Beckham, 41, works on her successful fashion empire.

Talking of his routine, he said: "I wake up, make breakfast for my children, take them to school. I go and work out after I've done that, then my little girl finishes at 12 o'clock, so I pick her up, take her for lunch and then take her home and go to the park with her.

"From there I pick my boys up and then take them to football practice, which finishes at nine in the evening."
