Biohacker who 'wants to live forever' reveals the one thing that's making you look older

A biohacker who's declared he 'wants to live forever' has detailed the one thing he reckons is making you look older - and it's a bit different from his usual advice.

Bryan Johnson is taking part in a lengthy and intense experimental medical program in the hope of 'reversing aging', something which he has dubbed 'Blueprint'.

Whether it be following an incredibly strict diet or using his son's blood, Johnson is doing everything possible to remain as young as possible.

While he may be 48 years old, the biohacker has previously claimed his crazy experiment helped him achieve the 'heart of a 37-year-old' and the 'lung capacity of an 18-year-old'.

In a video uploaded to YouTube in 2024, Johnson gave his take on 'how to not look old', and it involves some relatively simple advice in comparison to his usual strict regimes.

Johnson said: "A tan is a sign your skin is damaged. The sun is good, of course, for many reasons; it increases vitamin D, it can improve mood, and it can help with sleep.

"But it can cause collagen damage, and it can also lead to cancer."

The biohacker also noted that sun exposure can lead to 'saggy skin', which can be damaged and lead to wrinkles and discolor faster over the years.

So, Johnson explained how you'll want to be outside when the UV index is below three, which is usually early in the morning and later in the afternoon.

You'll want to stay out of the sun between 10.00am and 4.00pm, when the sun is at its strongest, according to Johnson. And yes, even when it's a cloudy day or during winter - and especially at higher altitudes.

However, for some, it's impossible to avoid those high UV levels, especially for those who have a job which involves outdoor work.

In that event, Johnson recommends wearing sunscreen with guaranteed UV protection, wearing a hat, or using a UV umbrella.

With too much sun exposure comes the increased risk of developing skin cancer, including melanoma.

Skin cancer is one of the most common cancers in the US, with the American Academy of Dermatology Association estimating a staggering one in five Americans will develop the disease in their lifetime.

Sunburn accelerates skin ageing and is a leading cause in the majority of cases of basal cell carcinoma, squamous cell carcinoma and melanoma - the deadliest form of skin cancer, the SCF states.

On top of an increased cancer risk, there's always the chance of developing severe sunburn in the form of sun poisoning, which can include symptoms such as fever, chills, nausea, headache, and blistering.
