From Yahoo News:

“What is it that defines happiness for an individual?” Aniston said. “It’s different for every person. So I think it’s a lot of projection to be quite honest and I’m so content and so happy where I am, knowing that whatever is going to be, will be.”

In a world of instant “TMI,” privacy is wishful thinking. But Aniston is holding on to what she has left, refusing to join Twitter.

“If I took to Twitter or anything, I would really send people over the edge,” she said, “probably just correcting every false rumor.”
