Well he just « overhauled » them… which I’m going to interpret as laying off a bunch who didn’t flag this to him earlier. If you just got hired by a billionaire who fired everyone on the prior team for not catching something, and is paying you to be brutally accurate are you going to order 1 biopsy? 2?

One gives you a high potential for false positives or negatives, two data points with opposite results is just as useless. Three is the gold standard to create a consensus among sensors, a lesson Boeing learned with their angle of attack at the cost of many lives.


> He publicly shares everything about his lifestyle and routine rather than paywalling them, so if he is running a scam, he probably needs some pointers

Disagree. What he does is run a YouTube channel that appears to do that. That makes it an ideal vehicle to advertise supplements with little research or scientific backing to an uninformed and trusting audience.


Each day the stock market likely moves his NW more than the ARR of his supplement company.

Again, if he is trying to run a supplement scam with an NW north of $1B, he needs some pointers. Dude could announce an AI startup tomorrow and get more funding than any of his current companies would make in a lifetime.


Ehh, you’re giving the guy a lot of grace cause he’s rich. I believe the GP was correct and have anecdotal evidence to support that he may be deceptive.

I followed him very loosely 3 years back and he was touting the effectiveness of a hair dye that he claimed permanently restored hair color at the follicle level if you followed their prescribed routine. As in no more greys, permanently. The company was called Mayraki and nobody had ever heard of them before Bryan’s videos and while I’m not saying he was scamming, I find it likely something dubious was going on with a high likely hood of him being paid for this advertising.

He went as far as saying he had his medical team biopsy his scalp and found the hair was not grey below the skin line so therefore was 100% true. It was quite a convincing narrative at the time to try this $100 hair dye.

The internet, especially Reddit, is now full of angry people with grey hair (and less money) that claim this product didn’t do anything beyond a regular dye but for 5-6x the cost. I can attest to this myself.


The article seems to be a meta analysis of a bunch of conflicting research to support a narrative that we don’t really know shit.

And fair, we don’t.

But a couple of things we do know that weren’t covered - egregiously so - is that aging is UV damage. Sometimes called photoaging, wrinkles, sun spots, discoloration, fine lines, grey hair, all of that shit that you associate with someone visibly looking old is sun damage.

So the picture that the article paints of some pasty nerds in offices shielding themselves from all UV and thus: they might as well be smoking… it doesn’t even touch on why people might be doing this.

Both kurgezadt and veritasium did some really great videos on photoaging and it’s worth checking out if this is new information to you.


I often embarrass my daughter when she has some new friend over. If the topic comes up, I give a demonstration. I'm 62 and I've never tried to get a tan and work indoors, and I haven't had a serious sunburn in close to 40 years. On the other hand, I lived spent the last 20 years in Austin, TX. I mow the yard and I ride a bike and in the summer months I put on sunblock before doing the bike rides an sometimes mowing.

The exposed parts of my arms look like I'm 62 -- freckles, some age spots, the skin has lost a lot of elasticity. But then I roll up my T-shirt sleeve to expose my shoulder and my skin is like it was when I was 25: not just pale, but no freckles, no age spots, still supple.


Photo claiming to be a 92 year old woman who used suncream on her face, but not her neck, for 40 years:

https://i.ytimg.com/vi/ITlo7TAy_Hs/maxresdefault.jpg

(She also appears to have Frank's Sign: https://en.wikipedia.org/wiki/Frank%27s_sign )


and then staying in the sun too long, over and over again.

Don’t forget that step.


I see no mention of that in the picture I linked for me to have 'forgotten'? Or in the longer article where it appears: https://onlinelibrary.wiley.com/doi/full/10.1111/jdv.17660

That seems to be something you have 'hallucinated'?


You think that happened to her from a single exposure?

A handful of exposures?

She looks like a football! Who’s hallucinating?


92 years is 33,000 days of being alive, that's plenty of time to rack up damage without doing anything for "too long".

If she had tooth decay or dentures would you say she must have been "chewing for too long"?


Chewing bacteria and or acid for too long, yeah. Like most people.

It’s easy to explain away degenerative effects as primarily age-related - until you look at healthy old people.

About whom the model just says “statistical outlier” and moves on.


the culprit is not the sun-- but overdoing it. If you overdrink water, it is fatal, too.

The sun is responsible for benefiting over 200 processes in the body. And you don't need to be out in the sun all day to get the benefits (if your job does not demand it).


It's far harder to overdrink water than it is to overstay in the sun.


Pro golfers look a good 10-20 years older than their real age sometimes fwiw. In contrast to most other pro athletes in indoor disciplines who generally look better than their age. There's also examples of truckers who spent most of their career with the window rolled down and you can tell straight up what side of the road they drove on.


I first took sun exposure seriously after backpacking and spending time with other young travellers in hostels. It was apparent who spent their time exposed to the sun, I remember a girl my age who was in the middle of a multi-year cycle tour, and although I envied her journey, her skin looked quite rough. I decided that if I ended up doing that, I'd get one of those cycle helmet brim visors and would probably just cover my face during a lot of the riding portions.

Then I met a man who did kayak tours of a city. He was awesome, but really leathery due to the 20 years in a boat without shade and having the UV reflections off the water. Your skin cancer risk is off the charts at that point.


I used to work on boats in the Caribbean.

After my first few months there I realized that the people who didn't look like an old leather bag wore long sleeve shirts and big hats pretty much constantly.


Truckers, plural? Is there an example that isn’t William McElligott from the famous photo[1]?

Edit: self answer, yes[2] (left side!)

Those drivers don't even need to have the window rolled down as far as I know. That's because most door auto glass lets UVA rays through and that's what causes premature aging. If you want to block those UVA rays, you would need to apply some kind of additional film to the side window.


The sunny side of the road?


> kurgezadt

I suffered with German too, in fact, still do :)

As a trivia: "kurz gesagt" -> kurz: short, gesagt: said. "sagen" is the verb "to say", "ge"+"t" is to form the past participle. (but not always :)


I've not heard that grey hair is sun damage.

Do you have any sources for that?


There’s plenty, though please evaluate the veracity of their claims for yourself, I’m not a scientist nor do I excel at parsing scientific articles. Here’s one I’ve come across after a few minutes which references many others https://www.sciencedirect.com/science/article/abs/pii/S10111...


After a quick skim, that article seems to be talking about something other than typical age-related greying. More photobleaching.


From the conclusions:

> Sun radiation affects hair properties as color, luster, mechanical resistance, the content of proteins and others.

TLDR Yes it impacts color. Further reading can be found in the 75 studies that can be found in the references section.


If hair greying was mostly caused by UV damage, I would expect that the pattern of greying would be even, and begin on the top of the head.

In contrast (based on my own unscientific observations!) greying typically begins in small areas, and often on the temples - not what I'd expect if caused by UV damage.


Now I'm curious why it starts on the temples (it's where mine started too, then my fringe)


When most people think of age-related hair greying (which you referenced in your original post), they think of the phenomenon whereby hair follicles stop producing pigments that colour hair.

This is distinct from UV bleaching of the pigments in the hair.


Which grows out. So if it was substantial, you can just stay inside a while and eventually your hair will grow out and replace the faded hair.


If you compare President Obama photos (2008) to President Obama photos (2016) you may conclude that he spent most of his time lounging on the beach?

I'd rather look old than be one of those lunatics who goes for a summer walk in a longsleeve shirt, gloves, and a hat with built-in veil (a pretty common sight in the Bay Area)


Sounds like my parents, I would always sweat our beach walks with my mom wearing a nose protector that resembled a beak


Who cares about your skin looking a little older when it prevents cardiovascular related deaths??


Worth noting here for any readers new to UV guidelines that the above rule isn’t necessarily helpful for you. I’m currently traveling in an area that is 8:30am-4:30pm and live in an area that’s 10-6 pm in the summer and shifts throughout the year.

The actual rule is derived from your location’s safe UV index zones, which is found out by determining what local time the UV Index <= 2. Above 2, wear some amount of protection.


That's basically sun up to sun down, here.

It's been completely grey, overcast, and raining here all day and the UV index sat between 3 and 5.


The worst sunburn I ever got was on a boat while overcast. I don't trust them clouds no more.


Clouds block a decent amount of UV on average, but it’s much less consistent than you might expect. 9/10 you might be completely fine with no sunscreen and then get a horrible sunburn the tenth, with no apparent visual distinction between them.


Ya, the relationship between UV and sunlight is strange and unintuitive. For that reason I use a UV widget on my lock screen.

I find that being exposed to the value (e.g. 4) while being able to see the suns effect (e.g. cloudy) gives me a better feel for conditions.


There was no cheer in the comment you’re replying to, just facts. The fact that you misinterpreted that is strange.

The fact that you have strong feelings about having your children reviewed by other adults for signs of abuse and neglect is stranger.

You do understand how children are vulnerable and parents aren’t always reliable, yes?

Homeschooling your children can be done well, in theory. However the majority of the time it’s done by imbeciles for religious, political or pseudo-medical reasons and results in children far less educated than the system you criticize and who are also imbeciles.

This is a form of abuse that will destroy a child’s potential far more readily than the four core elements above that you seem to be protesting.


I wasn’t going to say anything until I read this comment but that clip of the gameplay and the clip of the two people playing are not from the same source. The one showing the gameplay has a tower of books or possibly a jenga tower on the coffee table that doesn’t exist when seeing the gamers. It’s just editing magic and stitched together to have exactly the effect elicited by your comment.


The books are beside the TV, not on the coffee table. You can't see them in the second shot.


Ah, I think you’re right. That aside, there’s still no evidence of continuity between the two shots and I’m a cynic.


They're two separate shots that's for sure. I mean, otherwise you'd see the other camera taking the shot from the opposite perspective so...


Hey Jeff, I did some research on the jetkvm after reading this as I was very impressed but wanted full scale hdmi + Poe and was going to pull the trigger on the clone you mentioned later, ArkKVM but felt like I’d rather support the main project if I could…

What I found seems to indicate that Jet fixed those two issues in a hardware revision but it’s really difficult to distinguish the new on from the old as they’ve seemingly kept the same name and not added a v2 or something like that to the naming. One of their vendors has a Poe va non poe sku, the other has a an emmc vs tf card sku. All seemingly without a name distinguishing them.

There’s also just chaos on Amazon as they are being sold in at least 4 separate listings with no name distinguishing which model is which, non of them mention poe and all claim full size hdmi.

In any case I thought you should know that your write up is out of date here but you probably need to do some digging to figure it out.


Indeed, I will add a note in my blog post. They should've called it V2 or something.


This is such a fascinating comment. I’m 99% confident you discovered that you have a recessed lower jaw in the most roundabout way possible, and may never have connected this last dot in your chain of troubleshooting had I not told you.

I’d urge you to speak with a maxilofacial surgeon, they will confirm it by taking detailed X-rays of your jaw and will be able to identify that your airway is likely impacted by the recession.

Usually the causal chain is such: Recessed jaw due to poor development as a child, likely a pacifier or a stomach sleeper > causes your tongue to not have enough space and puts backward pressure on the airway constricting it > poor sleep.

Usually people with recessed jaws have a variety of other mouth related problems too like mouth breathing, gum recession, abnormal amounts of cavities, bruxism, pain and poor bite. If youre lucky a dentist might have caught some of that and flagged it to you but usually they send you to an ortho who magically discovers that this can all be solved by pulling some teeth as a teenager and giving you braces.

This actually makes the situation much worse and you only find out in your mid to late 20s.


Web dev here.

Many years ago I switched over to FF as my default browser but something kept me from using it for development… Nothing that serious, just small quirks in its dev tools UX and behaviors that weren’t bad, just different.

What I noticed was that if I engineered sites for Chrome, they’d be broken maybe 10% of the time on FF when I eventually tested it and maybe 15% in Safari - especially mobile.

Wanting to limit the amount of bugs I put out in the world I changed my approach to developing solely in FF and occasionally testing in Safari and I can honestly say I’ve never had a bug reported in Chrome. It just works. Safari issues are now down to <1% and mostly involve their unique approach to z-indexing but these are entirely predictable now.
