Cameron Diaz thinks social media is a "crazy-ass experiment". The 'Bad Teacher' actress quit online networking in 2014 because she thinks it is "dangerous" and doesn't understand why people place so much value on the opinions of people they don't know. She said: "I think social media is a crazy-ass experiment on society. "The way people use it to get validation from a bunch of strangers is dangerous. What's the point?" Despite her slender figure, the 42-year-old beauty insists she is happy to indulge in sugary foods but knows it is important to have things in moderation. She said: "Wellbeing is an equation. Remember, you don't have to have the whole cake, you can have a piece. Don't deprive yourself. Have fun. Just be self-aware. "If your equation is 80% good, 20% bad most of the time, then a little movement toward the centre isn't going to affect you much." ."
