"I wouldn't want to be 20 now," the actress tell V magazine, in their special Age Issue, also featuring Jane Fonda and Sigourney Weaver. "I know so much more, and I'm much more comfortable in my skin, saggy as it is."
Sarandon says life's too short to spend it worrying about your body. "When I hear young girls complaining about superficial things ... You're at the peak of your physical beauty right now!" she exclaims. "Just enjoy it and stop worrying about your thighs being too big."
Adds Sarandon, "If you're upset with how you look at 25, life's going to be tough."
For Fonda, 72, with age comes a carefree mindset.
"There's fabulous things about being older," she says. "The older people get, the less scared they are. All the studies show you're not as anxious. People tend to have less hostility, they have less negative emotions. They tend to see things from both sides. Very few things stress me out."
Age has not slowed down Fonda at all. "I love being productive," she says. "I'm never bored. I'm always coming up with new things, whether it's making a DVD or a book, or making movies. I always want to exteriorize what's going on inside of me."
