The 80-year-old billionaire Larry Ellison wins plaudits for looking 30 years younger, with the longevity fanatic Bryan Johnson weighing in

• Larry Ellison, the cofounder of Oracle, is being praised for looking 30 years younger at age 80.
• The antiaging advocate Bryan Johnson highlighted Ellison's youthful appearance on social media.
• Ellison's regimen reportedly includes exercise and a strict diet.

Larry Ellison is winning praise online for looking far younger than his age.

Some people are only now starting to discover that the billionaire cofounder of Oracle recently turned 80.

Even the antiaging fanatic Bryan Johnson chimed in.

"Ellison, now 80, is doing a good job managing biological aging," Johnson, the founder of the payments company Braintree, wrote on X.

The biotech entrepreneur is known for his quest to prolong his lifespan and look younger. At one point, Johnson, now 47, participated in a trigenerational blood exchange with his son, Talmage, who was 17 at the time, and his father, Richard, then 70, to slow his and his father's aging processes.

In a 2018 Quora thread, Gina Smith, the former boss of one of Ellison's startups, said his more youthful appearance is due to a lot of exercise and a meticulous diet.

She said Ellison worked out for several hours daily when she worked with him in the 1990s and 2000s.

"He never drank anything other than green tea and water," Smith said. "And he's a so-called 'veg-aquarian.'"

She said this meant he ate vegetables, fish, and fruit.

"Larry's been doing this since I first met him in the early 90s. It shows," Smith said.

Some social-media users have questioned whether Ellison's had plastic surgery to maintain his youthful appearance, but as one user pointed out, surgical intervention can only get you so far.

"This guy is 80?? He doesn't look (plastic surgery only can do so much), sound, or move like an 80 year old. This guy seems more like he's in his 50s," one user on X wrote.

Ellison — who's worth $174 billion, according to the Bloomberg Billionaires Index — has donated millions to antiaging research .

He once told his biographer, Mike Wilson: "Death has never made any sense to me. How can a person be there and then just vanish, just not be there?"
