Ric Flair says his wife, Wendy Barlow, is "100 percent" the reason The Nature Boy is alive today ... telling TMZ Sports, "She's responsible for all of it."
Ric's had some close calls when it comes to his health the last few years ... he was on death's doorstep in 2017 and just a few months ago he needed a heart procedure to keep his ticker going.
Flair says the docs obviously did a great job piecing him together ... but tells us Wendy truly deserves all the credit for getting him back to being a jet flyin' son of a gun!!
"Doctors 20, her 80," Flair says of Wendy ... "No, 90-10. She's responsible for all of it."
As for how he's feeling now, after the heart procedure in May, Naitch tells us he's doing great ... saying, "Best I've been in 10 years!"
By the way, we also talked to Ric about Taylor Swift's new song, "The Man," and ya gotta hear why Flair has some issues with it.
Hint: As Wendy says, "Ya gotta beat the man to be the man!"
