Interestingly, in 2022 the FCC changed the range of acceptable EKG requirements for heart health required for pilots; previously the PR had to be between 0.12 to 0.2, and they widened it to 0.12 to 0.3. That would have allowed pilots with mild cardio injury (who are more likely to suddenly pass out) to fly.

First degree heart block (ie a PR interval > 0.2) is not a marker of mild ‘cardio’ (NB: it’s cardiac) injury. It does not cause syncope. It is a reflection of electrical timing between the cardiac chambers. It is not an echocardiogram or a RHC and will tell you nothing about the anatomy or physiology of a person’s heart other than timing. It is not a full electrophysiological study either.
There is no such entity as ‘mild cardio injury’ and I suggest you stop spreading nonsense. Pilots already have strict medical guidance for health and unexplained syncope is not something that is hand-waved away.

I think if it were a fact, it would be supported by argument and evidence. What we have here is simply a claim, which was not supported by any evidence. I am perfectly willing to accept that poorly thought out diversity policies can have adverse effects on organizations, which is especially troubling if that organization manages vital infrastructure. But I would need to see good evidence, and argument with that evide…
So if you don't agree with a claim, instead of asking for evidence you flag and terminate the discussion? This is what happened here.

I wonder, is there any way to expand short links without captchas.

ACT test scores have plummeted too. Combined with what we know about the physical brain changes that can be observed after a single mild infection, it all paints a potentially concerning relationship with COVID.
Could also be the consequences of schooling during a lockdown.
Those things don't necessarily have any relation, but clearly many countries with strict CoVID responses are still doing well in education.

People are driving spaceship-sized SUVs while using their phones, hitting pedestrians who are walking around looking at their phones, jumping out of the path of an oncoming 12yo doing 40kmh on a battery powered scooter while looking at porn on their phones and using Whatsapp to schedule a meet up with their Fastgas supplier. Their parents think that a scooter is a toy, the phone is so that they can call home, and the…
How does a technical gas supplier factor into the life of today's teenagers? I'm genuinely curious. Is our hypothetical 12yo person learning tig welding on a side?

What about the effects of an extremely wide and extremely quick deployment of a novel vaccine (under threat of being fired)?
Since vaccine testing requires giving half your study population a placebo and then waiting for them to get sick. Bit cruel really.

My pet theory has been that extended lockdowns caused regressions in people’s ability to drive safety, whether it was the actual skills to operate a vehicle, or people’s risk assessment skills. Operating a vehicle is a skill like any other, and if you’re not performing reps you’ll regress like any other activity. Empty roads might even permit crappier driving.
Perhaps, maybe, mass infection by a virus that affects the brain and vascular system has consequences for society.
I've been warning of software deterioration for the past few years and this seems to be an extension of the same effect. Likely the result of increasingly non-meritocratic employee selection processes and non-meritocratic incentive structures. Due to government interference in the economy (especially due to money printing), we've basically turned our capitalist system into a very poorly implemented communist system.…
I don't know any rich people with 10 girlfriends though. Rich people have just as much time as anyone else, likely even less since they usually work more, so that sounds hard to schedule.

Not Amtrak. Worst excuse for a railroad ever.
No experience myself, but from past comments on HN, I understand the company Amtrak provides pretty good service within the areas it can control. It's just that the US rail network prioritizes freight every time (even though legally it's not supposed to).
