Supermodel Elle Macpherson credits loving and laughing with keeping her healthy.

Elle Macpherson believes loving and laughing keep her healthy. The 45-year-old supermodel - who has sons Flynn Alexander, 11, and six-year-old Aurelius Cy Andrea with her ex-boyfriend Arpad Busson - believes she has maintained her immaculate looks because she spends time on her own to relax, meditate and laugh. She explained: 'I take time for myself, I meditate and reconnect and it keeps me healthy. I want to be around for a long time and I need a healthy body, and a healthy body means making sure I get enough sleep, enough vitamins, eat properly, laugh a lot and love a lot.' As well as keeping her mind healthy, Elle makes sure to keep herself physically fit too. She told Britain's Hello! magazine: 'I have less time than I used to, that's for sure. Physical fitness is important to me and not because I need to maintain the shape people think I should be, but because I enjoy being physical from a deeper perspective. When I'm in London I work with my trainer James Duigan at Bodyism, otherwise I surf, ski, waterski and hike.'
