Gwyneth Paltrow has revealed a combination of sex and "self discovery" keeps her young.
The Oscar-winning actress has often come under fire for her lifestyle advice on website Goop, but told OK! USA her philosophy on anti-ageing is simple.
She said: "Honestly, it's pretty basic stuff, like exercise and self-discovery. Looking at life as an opening and an adventure - and love and sex."
The Iron Man 3 actress said she had been discussing on-screen violence with her children recently.
"I'm dealing with this now with my seven-year-old [Moses]," she said. He's grappling with the fact that the world is unsafe and people do harmful things. After he saw Iron Man 3, we had a conversation about violence."
Gwyneth, 40, also said that her family with Coldplay's Chris Martin mattered more to her now than winning Academy Awards.
She said: "You realise that the love you have for the people in your life, and their love for you, is all that matters."
