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

• Larry Ellison, the cofounder of Oracle, is praised for looking 30 years younger at age 80.
• Antiaging advocate Bryan Johnson highlighted Ellison's youthful appearance on social media.

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 has recently turned 80.

Antiaging fanatic Bryan Johnson even chimed in.

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

The biotech entrepreneur is best known for wanting to prolong his lifespan and look younger. At one point, Johnson, now 47, participated in a trigenerational blood exchange with his then-teenage son, Talmage, and his then-70-year-old father, Richard, to slow his own and his father's aging process.

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 explained that this meant he ate vegetables, fish, and fruit.

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

Some social media users questioned whether Ellison has had plastic surgery to maintain his youthful appearance but still.

"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 commenter wrote.

According to the Bloomberg Billionaires Index, Ellison has a net worth of $174 billion and has donated millions to antiaging research.

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