When Gwyneth Paltrow lost her father to cancer 10 years ago, she got a big wake-up call. "When my father was diagnosed with cancer, it really changed the way that I lived – it changed my whole lifestyle", Gwyneth reveals in a new interview. "I completely changed my diet, and I got very serious about exercising and about exposure to toxins. This is my one life, and I need to invest in myself and my family and make sure that we can do what we can to stay healthy", she continued. Sounds like a good plan to us, Gwyn!
