Bryan Johnson warns against air travel as he flies to meet parents of girlfriend with 'top 1% vagina'
Biohacker Bryan Johnson has told people they should avoid air travel if possible as he claimed 'international travel increases aging'.
You might have heart of Johnson before as he's the man who is trying to reverse the aging process in his own body through a series of expensive and unorthodox procedures.
He's also got a girlfriend in the form of Kate Tolo, the Australian co-founder of his longevity startup Blueprint, and now they've been together for three years he's started talking about her 'one percent vagina'.
Apparently it's all to do with her 'vaginal microbiome report', as Johnson said: "Her sample is dominated by the single most protective bacterial species a vagina can host (Lactobacillus crispatus).
Advert
“Only about 25-30% of reproductive age women globally are L. crispatus-dominant, and ‘dominant’ usually means above 50%. Kate is at 98.7%.”
If you're inexperienced in the ways of romance it's probably a good moment to let you know it's probably a bad idea to be saying that sort of thing about your partner, unless both of you are really into this biohacking business.
Anyhow, Johnson and Tolo are flying to Australia so he can meet her parents and to prove how much he loves her he's willing to brave the frightening prospect of 17 hours of air travel.
Modern life has tricked us into thinking travel is good.

It's kind of barbaric for the body.
Last time I went to Asia we measured my biomarkers.
The data was bad…
+ 9 days for blood glucose stability
+ 9 days to re-entrain my circadian rhythm
+ 18 days for sleep…
According to the biohacker 'modern life has tricked us into thinking travel is good' as he said the last time he travelled a long distance the biological markers for his body all went in the wrong direction.
In his opinion if you really must travel by air then you should only go once every three months, as he reckoned it took a day per timezone travelled to recover from the journey.
"I hope that this is my last international trip for a very long time," Johnson posted on social media, so if Kate's parents want to see him again they're probably going to have to book tickets to the US.
On a more positive note from Johnson and his girlfriend's 'top one percent vagina', his biohacking work might actually turn into some positive steps around endometriosis.
Immortality might be out of our reach but making some real progress to a serious health issue that plagues a lot of women would be a genuine achievement.
Bryan Johnson’s wildest experiments in his quest to ‘live forever’
De-ageing his penis
While the thought of it may make you wince, Johnson has been putting his manhood through the wringer in the hopes of bringing back his '22-year-old penis'. From semen analysis and blood flow testing to Botox injections and shock wave therapy, he seems to have done it all.
The biohacker claimed to have been able to lower his 'erection age' by over half thanks to this long-winded ritual.
As well as keeping track of his own 'erection data', Johnson has also been controversially comparing the stats to his 19-year-old son's.
Injecting himself with his son’s blood
The biohacker went viral in 2023 after sharing that he'd come together with his then-17-year-old son and his 70-year-old father to take part in what he described as 'the world’s first multigenerational plasma exchange'.
The process saw Johnson have a litre of his blood removed and separated the plasma. He then had the same amount of his son's plasma infused into his veins.
However, after seeing 'no benefits', Johnson announced he was 'no longer injecting my son's blood'.
Instead, he said he 'upgraded' to 'total plasma exchange'.
Psychedelics
Last year, the biohacker documented his trip after taking 5g of magic mushrooms. Afterwards, he admitted he was 'happy to be alive', and the experience had 'changed' him, but 'probably not as you’d expect'.
Johnson also shared the effects of taking 27mg of the 'world’s most powerful' hallucinogenic, 5-MeO-DMT, which left him 'stunned beyond comprehension'.
An extensive morning routine
Johnson recently shared an update on what he does each morning, noting that it takes four hours and 46 minutes.
"My morning routine is always evolving as we update protocols. This is what I'm experimenting with right now," he writes on his website.
1. Wake up around 5 am
2. Oral hygiene
3. Light in eyes
4. Breath work
5. Pre-workout nutrition
6. Exercise
7. Sauna
8. Red/NIR light therapy
9. Focused shockwave therapy on joints
10. Shower
11. Hair growth serum
12. Skincare
13. Breakfast
