michael j. fox doesn't give a lot of interviews, but he just spoke with our dr. sanjay gupta, he's been living with parkinson's disease for two decades now. he was 29 when he first noticed the symptoms and was diagnosed the following year. today michael still acts but he devotes a lot of time to his charity he created to find a cure. you can see the entire interview tomorrow on cnn at 8:00 p.m. eastern. but here's some of it tonight in our "up close" segment. >> there was a real clear period around 1993, '94, about two years after the diagnosis where i just got it. i just accepted it. and i realized that there's an old saying that my happiness grows in proportion to my acceptance and in inverse proportion to my expectation. it is what it is, and so now what? >> so once you were not in denial you think you were happier?
