Youth-chasing US millionaire Bryan Johnson says S’porean Chuando Tan’s agelessness is ‘encouraging’

LOS ANGELES – Imagine spending millions of dollars on a public quest to become more youthful, only to face cruel comments about your resulting appearance.

Some people say you now look worse, and a few compare you unfavourably with Chuando Tan, the Singaporean photographer who went viral for his age-defying looks, even though he is a decade older.

This is the reality for Bryan Johnson, the 47-year-old American entrepreneur who, in 2021, embarked on a controversial one-man experiment to extend his longevity and reverse any age-related decline.

But his response to the backlash has been to take the high road, engage with critics and respond graciously to even the most savage detractors.

And he acknowledges that Tan, 58, appears to have found the fountain of youth with a much simpler lifestyle.

Johnson displays this disarming attitude in recent podcast interviews, as well as a new documentary, Don’t Die: The Man Who Wants To Live Forever, now streaming on Netflix.

If sensational headlines such as “Millionaire spends US$2 million a year to live forever” suggest an eccentric vanity project, the film adds nuance and humanises the man, who comes across as earnest, curious and humble enough to admit when some experiments go wrong.

Johnson’s programme, which he calls Blueprint, entails a rigorous diet, exercise and lifestyle regimen, as well as taking dozens of supplements and injections, including a novel gene therapy to boost muscle mass.

The technology entrepreneur, who made millions when his digital payments company was acquired by PayPal for US$800 million (S$1.09 billion) in 2013, was overweight, overworked and severely depressed as he was building his early businesses.

And he did become fitter and healthier after doing the Blueprint programme, but his rapid weight loss and pallor – the by-product of trying to avoid sun damage – attracted numerous negative comments.

In the film and on his YouTube channel, Johnson acknowledges that the haters had a point. Even though he had become healthier overall, he lost facial volume, and with it, the appearance of youthfulness.

Yet, despite a concerted effort to rejuvenate his visage, he is still routinely the target of barbed comments.

On an episode of the popular More Plates More Dates podcast released in December 2024, Johnson is shown a tweet in which SpaceX founder and Tesla chief executive Elon Musk, 53, agrees that he looked better before he began his anti-ageing journey.

But Johnson laughs good-naturedly, describes Musk as a friend, and embraces the joke often made about his vampiric complexion.

He is then asked about Tan, whom the podcast host cites as an example of “people who seemingly pay very little attention to what they’re doing and yet look way better than people who are doing everything”.

More on this Topic

Johnson reveals that he and Tan, founder of Singapore modelling agency Ave Management, had actually planned to meet. “I was just in Singapore, but didn’t get a chance to meet him,” he says.

Agreeing that Tan looks at least 20 years younger than his age, he adds: “I don’t fault people for being confused.

“They look at that person (Tan), and then they see the headline, ‘This guy is spending US$2 million a year’, and they conclude, ‘This guy should look like that guy in one year’s time.’”

Johnson argues, however, that this is because people do not understand “the biological principles of ageing” and advancements in rejuvenating technologies.

It would be interesting to run the same tests he does on himself on Tan, he adds. “What do his insides look like? Is it as pristine as his appearance?”

Still, the fact that Tan looks as ageless as he does is promising to Johnson.

“To me, that’s really encouraging because biology is capable of the things we’re asking it to be. We’re just trying to sort it out.”

Johnson’s programme measures health and ageing using dozens of biological markers, ranging from established metrics such as bone density and VO2 max – a measure of cardiovascular fitness – to esoteric ones such as DNA methylation “clocks”.

These clocks track chemical processes in DNA to determine “biological age” or if someone is ageing faster or slower than his age in years.

The validity of these clocks is still debated by scientists, but they are one of the main tools Johnson uses to calculate his speed of ageing, and the basis of his 2023 claim to have reversed his biological age by five years after two years on his protocol.

The Netflix documentary details the lengths he goes to daily to adhere to and document this demanding programme.

It includes swallowing 88 pills, eating a calorie-restricted vegan diet that always leaves him hungry, and something called “penis shockwave therapy”, which he hopes will boost his sexual health and performance.

He has also created a community that follows a pared-down version of his protocol and attends his Don’t Die Summits, where attendees get to test their biological age and see the latest longevity-boosting therapies. One was held in Singapore in September 2024.

But equally fascinating is what drives Johnson to do it all – a touching backstory that includes growing up with little money, becoming estranged from his family, then reconnecting with both his father and his 19-year-old son.

Whatever you think of the longevity goal, this is a father making up for lost time – and trying to extend that as much as he can. - The Straits/Asia News Network

Understanding vitamin D

 
This ‘sunshine’ vitamin is particularly important for a growing child as it is essential for bone and immune health.


As a parent, you may have heard of vitamin D in passing, often linked to healthy bones or sunlight.

However, vitamin D is more than just a nutrient; it’s a vital component of your child’s overall health.

This “sunshine vitamin” helps regulate calcium in the body, supports bone development and plays a crucial role in immune function.

But what happens if your child doesn’t get enough of this vitamin?

In today’s column, let’s explore the importance of vitamin D, the risks of deficiency and how to ensure your child gets enough of this essential nutrient.

Why it is important

Vitamin D is actually a prohormone, which is a precursor to a hormone.

It is mainly produced in the skin upon exposure to sunlight.

It comes in two main forms: > Vitamin D3 (cholecalciferol)

Produced in the skin after sunlight exposure, it is also found in fortified foods like milk, dairy, fatty fish, liver and egg yolks, as well as many supplements.

Vitamin D3 is more effective than other forms of vitamin D. > Vitamin D2 (ergocalciferol)

Found in plant-based foods, fortified foods and some supplements.

Once consumed or produced by the body, both forms of vitamin D are converted into an active form known as calcitriol (1,25-dihydroxyvitamin D).

This active form is essential for:

>

Regulating calcium and phosphorus

Vitamin D is essential for the absorption of calcium and phosphorus from the intestinal tract, both of which are necessary for healthy bones.

Without enough vitamin D, the body can’t absorb adequate calcium, leading to weakened bones.

> Promoting bone health

Vitamin D is crucial for building strong bones.

Without it, children can develop rickets, a disease that leads to soft, weak bones, and deformities like bowed legs.

>

Helping immune function

Vitamin D helps the immune system function properly, enhancing the body’s ability to fight infections.

A deficiency may increase the risk of childhood respiratory infections like colds and coughs.

Importance of getting enough

A lack of vitamin D can lead to several health issues:

>

In severe deficiency

The most well-known consequence is rickets, a condition that causes soft and weak bones.

This leads to deformities like bowed legs, a curved spine and a bulging chest.

severe deficiency may also result in hypocalcaemia (low calcium levels), leading to muscle spasms, heart failure or seizures in infants and children.

>

In mild deficiency

Less severe deficiency can still have lasting effects.

Children with low vitamin D levels may have weakened bones, making them more prone to fractures.

symptoms like muscle aches, fatigue or general tiredness can also indicate insufficient vitamin D.

Additionally, there are studies linking vitamin D deficiency to other health conditions like respiratory infections, allergies, autoimmune diseases (e.g. type 1 diabetes), and even cancer, though more research is needed in these areas.

While sunlight is the most natural source of vitamin D, other sources include food and supplements.

Here are some ways to ensure your child gets enough of this vitamin:

>

Sunlight exposure

Vitamin D is produced in the skin when exposed to sunlight.

For fair-skinned children, 10 to 15 minutes of daily sun exposure on the face, arms and legs is typically sufficient.

Children with darker skin may need more exposure as their skin contains more melanin, which reduces the ability to synthesise vitamin D.

However, excessive sun exposure is not recommended due to the risk of skin damage.

Even in tropical regions like Malaysia where sunlight is abundant, many children still suffer from vitamin D deficiency.

Factors such as indoor lifestyles, wearing clothes that block sunlight, air pollution and the use of sunscreen can limit vitamin D synthesis.

>

Dietary sources

Although sunlight is the main source, foods can supplement vitamin D intake.

Foods rich in vitamin D include fatty fish (e.g. salmon, mackerel, tuna), fortified foods (e.g. milk, dairy products, breakfast cereals), egg yolks and beef liver.

>

Supplements

In many cases, especially when sunlight exposure and dietary intake are insufficient, vitamin D supplements are necessary.

The general recommendations for daily vitamin D intake (from food and supplements) are: 400 IU for babies aged up to 12 months, and 600 IU for children aged one to 18 years.

A much higher initial dose might be needed if a child has vitamin D deficiency as confirmed with a blood test, or in thosewhoareatriskofsucha deficiency.

supplements come in various forms, including liquid drops, chewable tablets and gummies, making it easier for children to take.

If you suspect your child may not be getting enough vitamin D, consult with their paediatrician.

While calcitriol can be prescribed, it should not be given to replace simple vitamin D deficiency due to the higher risk of side effects as it is already activated.

It should only be prescribed for specific medical indications with advice from a paediatric endocrinologist.

Those at risk

Certain factors increase the likelihood of vitamin D deficiency in children:

>

Limited sun exposure

Children who stay indoors most of the time or live in places with long winters may not get enough sunlight.

>

Dietary restrictions

Children who follow a vegan or vegetarian diet may lack adequate vitamin D.

>

Chronic illnesses

Children with conditions like coeliac disease, cystic fibrosis, obesity or other medical conditions may struggle to absorb vitamin D properly. >

Medications

Certain medications, including steroids and anti-epileptics, can interfere with vitamin D absorption.

> Dark skin

Children with darker skin tones have higher melanin levels, which reduces the body’s ability to produce vitamin D from sunlight.

If you suspect your child has a vitamin D deficiency due to inadequate sun exposure, poor diet or any other risk factors, it’s important to consult a healthcare provider.

Blood tests can measure vitamin D levels in the body, and if a deficiency is found, your paediatric endocrinologist or paediatrician will recommend a treatment plan.

In conclusion

Vitamin D is essential for healthy bones, a strong immune system and overall health.

Ensuring that your child gets enough vitamin D through a combination of sunlight, food and supplements can help them grow strong, healthy and resilient.

If you suspect your child may have a deficiency or if they fall into a high-risk category for vitamin D deficiency, it’s important to consult with their healthcare provider.

Through proper prevention and treatment, vitamin D deficiency can be easily managed to support your child’s long-term health.
