The 80-year-old actress made an appearance on Friday's episode of The Ellen DeGeneres Show, where she revealed she never thought she'd live to be as old as she is.
"If you had told me when I was 20 or 30 that I would actually still be acting, still active at 80 on a show like this, I would have said, ‘You're out of your mind. There's no way,'" Fonda admitted. "I didn't think I'd live this long. Every day I get up and I want to pinch myself."
"I feel very blessed, but I've worked for it," she added.
The Book Club star said she thought she'd "die lonely and probably from alcohol or something like that." "The fact that I'm not an addict, and I'm 80 and I'm working, it's just a miracle to me," she said.

A year after leaving Ted Turner, former actress Jane Fonda says she has radically changed her life - giving up her famed exercise regimen to write a book about her controversial days as a Vietnam War era peace activist. In an interview with Barbara Walters for ABC's "20/20" to be aired February 9, 2001, Fonda, 63, whose workout videos helped spark the fitness craze of the 1980s and '90s, said she has largely given up exercise because it interferes with her writing. She is shown in a September 26, 1997 file photo.

BACK TO SLIDE
These days, Fonda -- who revealed she wouldn't want to go back to her 20s "for anything" -- isn't sweating the small stuff, after learning what she's been able to overcome. The actress' mother, Frances, committed suicide when Fonda was 12 years old. She also had a decades-long battle with bulimia and overcame breast cancer in 2010.
"If you have a whole lot of time behind you and just a little in front of you, as is the case with me, I can look back and say, ‘Well, I've survived that,'" Fonda told DeGeneres. "You know, friends have died. There's been divorces, there's been all kinds of difficult things. I survived. You don't sweat the small stuff, right? You don't make mountains out of molehills."
And to go with her new laid-back attitude, she's got tequila -- lots of it.
"I have a bar," she said. "I've been married to three alcoholics. I love them all. They're great people, but I never had a bar. My last boyfriend had a bar in his house. What I realized is it's great to have a bar. It's like a focal point, a social focal point. So then I had to go and get the best tequila, the best vodka."
