Supermodel Naomi Campbell has revealed she likes to take a holiday every six weeks in order to keep calm. The leggy catwalk queen says taking frequent vacations from her busy work schedule helps to keep her notoriously difficult temper under control. “I learned that I need a break every six weeks,” she explained. “When I overwork myself I lose control. Now I know that it’s better to disappear for a while at the right time.” Naomi also revealed she takes care of her body by eating healthily and not drinking, but she thinks she has an unfair advantage in the beauty stakes. “I’ve got my mum’s good genes!” she says, adding her age doesn’t bother her. “I don’t worry about my age. on the contrary, I like telling people I’m 40. When you worry too much, you show these worries. I try to avoid that.”
