Paulina Porizkova is proud of her age.

The 56-year-old supermodel posed poolside in a string bikini on Instagram Thursday, showing off her amazing abs and natural gray hair.

And in her caption, Porizkova shared her candid thoughts about society’s dangerous obsession with staying youthful.

“Combat age. Reverse aging. Rejuvenate. Anti age. None of this is possible. Yet, if you do an internet search on aging, this is what you’ll get. Pills, potions and workouts to fight the aging process,” Porizkova began.

“You know [what’s] the only way to stop aging? Dying.”

The catwalk vet added that she has no interest in battling her body, and rather chooses to celebrate it.

“I do not want to fight myself everyday for the rest of my life,” she wrote. “But I do want to make the best of what I was given. And I want to shine a bright light in the dark corners of the shame that is heaped on women for daring to age.”

Porizkova also shouted out a number of other women who are all about “accepting their aging and making it beautiful” — including Andie MacDowell, Maria Shriver and celebrity makeup artist Pati Dubroff — and added the hashtags #nobotox, #nofillers, #nointerventions, #nofilter, #noshame and #proaging.

The Czech beauty previously opened up to Page Six Style about her candid social media snaps, telling us, “The more I posted the reality and the real me, the more people responded to it.”

Added Porizkova, “I think we’ve made enormous strides in accepting all different sorts of beauty; I think size and color and all of these things that used to be so uniform now have broadened to a pretty spectacular [degree] … But age, ageism, that’s kind of like the last frontier.”

The fashion icon, who went viral earlier this year after posing “full-frontal nude” (and completely unretouched) for the cover of Vogue Czechoslovakia, also told us that while she has never used Botox or fillers, she’s not opposed to a little help from lasers and other noninvasive beauty treatments.

But she also knows better than to expect miracles.

“Look, cosmetics and skin treatments are not going to do plastic surgery on you,” she explained. “It’s not like you’re going to use them and you’re going to look 20 years younger. It’s not only not realistic, but it’s impossible.”
