• Billionaire entrepreneur Mark Cuban said longevity is advancing so much that 60 is the new 40.
• While anti-aging science can be high-tech, what Cuban has shared about his own routine is simple.
• His low-cost longevity habits include walking regularly, eating vegetarian, and taking vitamins.

Mark Cuban isn't ready to act his age.

Speaking in the new anti-aging science documentary "Longevity Hackers" (streaming on Amazon and Apple TV) the billionaire businessman of "Shark Tank" fame said he feels decades younger than his biological age of 66.

"60s are the new 40s," Cuban said."You see guys my age in their 60s that can look good, can be fit, and not be limited in terms of things that they do."

While some entrepreneurs are spending millions on anti-aging routines, what we know about Cuban's routine is relatively simple — and doesn't cost much to follow.

Here's what Cuban has said about the diet, exercise, and supplements that keep him feeling youthful.

"If I never had to look in the mirror, I'd think I was 35," he said.

He walks as much as possible — including on the set of 'Shark Tank'

Exercise has been a major part of Cuban's routine for years, and it's crucial to healthy aging.

"I actually work out more now than I did 10 years ago or 15 years ago because my body needs it more," he said.

The entrepreneur said he typically spends between 45 to 90 minutes in the gym, including plenty of cardio.

He also stays moving whenever possible. While Cuban is not slated to star on "Shark Tank" in 2025, he said previous seasons of the show were a great opportunity to get his steps in.

"Everybody else is taking the carts, the set is .35 miles away, and I'm walking back and forth so I'm walking two miles a day while we're shooting Shark Tank," he said.

Walking more is also linked to a longer, healthier life, and as little as 500 extra steps a day can make a difference, according to research.

He's a vegetarian

Cuban has followed a vegetarian diet since 2019.

"When you get older, food becomes more like medicine where you need the nutrients in order to be able to be your best self," he said.

Plant-based diets rich in nutrient-dense foods like greens, whole grains, nuts, and beans are linked to a longer life and lower risk of chronic diseases.

"What I eat really makes a difference in how everything in my body operates," Cuban said.

Cuban said he enjoys plant-based food — and he's invested in plenty of vegan and vegetarian food companies — but the downside is that it can make it tricky to dine out or attend events.

"I love being vegetarian. It can be weird when you're with a bunch of guys going to a steakhouse," he said.

He supplements with vitamin D and melatonin

Cuban rounds out his nutritional needs with daily supplements to reduce inflammation and improve sleep, he previously told Business Insider.

He supplements melatonin, a hormone naturally produced by the body to regulate its internal clock.

Cuban also takes vitamins D and E, both of which are linked to healthy aging. Vitamin D helps the body absorb calcium, which is crucial for healthy bones, while bolstering the immune system to lower the risk of cancer. Vitamin E also supports the immune system and lowers inflammation, reducing the stress on cells to potentially stave off age-related damage.

He said being able to invest in his health with simple, daily habits has paid dividends by allowing him to keep up with the activities in his life that matter.

"To me, aging is just being who are you regardless of what the number is," Cuban said.

• Aritificial Intelligence is likely to disrupt the global workforce, research shows.
• Mark Cuban believes impacted jobs will be those that require simple yes or no decisions.
• Cuban told BI that the impact on a company's workforce will depend on how well AI is implemented.

Billionaire Mark Cuban doesn't believe artificial intelligence will devastate white-collar work.

In an interview published Thursday on "The Weekly Show with John Stewart," Cuban said he believes the fast-advancing technology will not impact jobs that require workers to think.

"So if your job is answering the question, 'yes or no,' all the time — AI is going to have an impact," he said. "If your job requires you to think — AI won't have much of an impact."

Cuban, the CEO of Cost Plus Drugs, an online prescription service, said workers must supervise AI and ensure that the data the models are being trained on and the resulting output are correct.

"It takes intellectual capacity. So somebody who understands what the goal is, somebody who's been doing this for years, has got to be able to input feedback on everything that the models collect and are trained on," he said. "You don't just assume the model knows everything. You want somebody to check — to grade their responses — and make corrections."

AI's recent advancement has raised existential questions on the future of work.

The World Economic Forum reported in 2023 that employers expected 44% of workers' skills to be "disrupted" within five years, requiring a massive effort on worker retraining.

A McKinsey study, however, found that AI won't decimate white-collar roles such as those in legal or finance. Instead, AI can potentially enhance those jobs in the long term by automating about 30% of overall hours worked in the US.

Cuban told Business Insider in an email that AI's impact on any company's workforce numbers will be on a case-by-case basis.

"Every company is different," he said. "But the biggest determinant is how well the company can implement AI."

• Mark Cuban learns about new technologies and trends through his teenage kids.
• Knowing about social media also allows the billionaire to connect with them.
• Cuban recently left "Shark Tank" to spend more time with his kids.

Social media may feel like unchartered territory to some parents — but Mark Cuban is leaning in.

In an interview with People posted on Thursday, the entrepreneur shared eight rules that he follows in life — including this one parenting tip.

"Number one, follow the scroll," Cuban, 66, said. "Oh my goodness, I learned so much from my kids. I learned what 'skibidi' is," he said, referring to the Gen Alpha lingo. "Skibidi Toilet" is an animated YouTube series about singing and dancing toiletlike creatures that want to take over the world.

Social media is an integral part of their lives, he added. "I keep on learning from them because they are exposed to all these new technologies."

Referring to himself as a "tech guy," Cuban said he tries to understand how social media algorithms influence his kids' lives.

Knowing about social media also helps him connect with them.

"They're in the car, and I'm driving my son. I can look over at a stoplight and see him scrolling through his Instagram or TikTok and know exactly what he's interested in," he said.

"Trying to be able to connect to him, which, like for any parent, could be almost impossible, but it's just informative," he added.

Cuban has three kids, who are 14, 17, and 21.

In May 2020, he posted a video on Instagram of him dancing with his daughters. "Teaching me to dance 😂😂😂," he wrote in the caption.

Last November, Cuban announced that he would leave "Shark Tank" after Season 16, which premiered in October on ABC.

"I'm leaving just to spend more time with my kids — they're teenagers now," he told The Wrap in October. "We shoot in June and September, and just getting the opportunity now when they're getting out of school to be able to spend time directly with them, that's important. I'm tired of missing that."

Cuban is not alone in using social media as a tool of connection.

Nina McCollum recently wrote for Business Insider that she uses TikTok and Instagram to communicate with her teenage son. They watch social media content together and have discussions about them.

"Politics, religion, science, life choices, and risk-taking are just some of the discussions social content has sparked," she wrote. "None of this connection would be happening if we didn't communicate through these videos."

A few celebrity parents have resorted to other means of connection.

"Modern Family" actor, Julie Bowen, said she hangs out around the house so her three teen sons know where to find her if they need her.

"If you just kind of park it, make fake cookies in the kitchen no one's ever going to eat, they start coming in and out. You start having conversations with teenagers," Bowen said in an October episode of "The Three Questions with Andy Richter" podcast.

Molly Shannon, a "Saturday Night Live" alum, advised parents of teens to change their attitudes about parenting in an interview on "Today with Hoda and Jenn." She added that they should have empathy when interacting with their teens.

"Most of the time, they just want to be heard. I try to think of that," she said.

Cuban did not immediately respond to a request for comment from Business Insider sent outside regular business hours.
