Thanks, when the system is fitted the locks in the hotel are mapped onto the front desk unit. You can issue keys for various levels with the lowest level being the guest's keycard which is only valid for their room and then individual floor access for housekeepers, then master keys for management and maintenance right up to the emergency key which is used by security which does everywhere in the hotel even secure areas like finance offices and bar cellars. The emergency keys open the rooms even if they're locked from the inside (in case the guest has collapsed).

If you lose or wipe your room key the receptionist will issue either a duplicate key or a "one shot key" (clue is in the name) but when a new guest checks in they get issued a new key. The front desk unit has a set of "rolling access codes" which match the memory in the lock so when the new arrival swipes their key the memory on the lock moves on to the next code making the old code invalid. Once this has been done 999 times it starts from the beginning again.

It was "legally taken" in about the same was as Paris was "legally occupied" by Hitler and Black people were "legally enslaved and bound to forever serve their masters". It has no meaning to us today.

Saying the Elgin marbles were "looted" is not a loaded term, any more than saying legally enslaved Blacks were "murdered" is a loaded term, just because it was legal.

In a good example of correlation not meaning causation.

What's going on is this - some small population of people always have the flu at any given time, they're just the unlucky bunch. Now the flu itself needs to survive the journey from person to person, this might mean being suspended in the air in droplets, or lingering on surfaces. The flu does best in moderate conditions, somewhat humid to dry air, and middling to cooler temperatures.

Now think about a nice, hot sunny day. Everyone is generally outside where the air is blowing away the germs AND it's not an environment the flu can survive in easily anyway. So, probably not a lot of chance of a flu epidemic in nice, warm sunny weather.

Now lets go your cold and miserable day. You're focusing on the outdoor exposure, but what were you doing before and after? You were indoors, with all these other people avoiding the weather, in conditions the flu LOVES, no breeze, moderate temperatures, everyone touching everything. That's how the flu spreads.

Yes, cold weather can stress your body and weaken your immune system, but as you mentioned, being cold and wet does not give you a virus.

Another important point is cold air is generally very dry. When you're stuck indoors all winter, breathing that dry air it causes damage to the lining of your nose and throat, kind of like getting chapped lips inside your body. That damage means the flu can travel through the skin in those areas making transmission all the more easy.

Same way AARP gets discounts for its members, Insurance companies pay less than self-pay, and Unions get better wages: collective bargaining.

Say GoodRx wants to offer a discount on aspirin. They go to Bayer and say "hey, we represent a million customers. If we can promise that 500,000 of them will buy Bayer aspirin instead of store brand generic, will you give us a discount?" Bayer thinks for a minute and replies "our analytics team has found that only 33% of consumers will spend more for our brand vs generic. If you can guarantee 20% increase, we'll give you 15% off." (Or whatever the real numbers are, I made those percentages up for demonstration purposes.)

GoodRx is essentially selling customer loyalty to pharmaceutical companies. Guaranteed, albeit reduced, returns vs the uncertainty of typical marketing.

It is low but not that low (fraction of a fraction etc). The four largest economies in the world

US 1.3%

China 22% (expected since it is still developing compared to others)

Japan 1.2%

Germany 1.2%

Adding UK (5th or 6th) ~1% and India 45%

these kind of pathogens are generally " everywhere" as in in every surface that isnt medically sanitized, meaning you are very likely to be a carrier, willing or not.

being unexpectedly exposed ot the elements can place additional stress in your immune system which can allow these pathogens to slip past.

This is science. The whole point of research is that we don't know the answer.

The way it work is someone comes up with an idea, and then it gets fleshed out into a hypothesis, and then people come up with ways to try and prove it. It doesn't always work -- sometimes it turns out the hypothesis was incorrect, and sometimes we just don't know how to prove it. Doesn't mean we don't try.

And frankly it's the same with the philosopher's stone. Just because we know now have the hindsight that it was completely bonkers doesn't mean they shouldn't have tried at the time. This is how science advances.

I didn't realize this until I was touring the Parthenon. I had assumed it had slowly crumbled over the centuries. It's definitely a strange emotion to know that it likely would still be glorious if not for people fighting.

Many ancient "pagan" structures were treated by subsequent (Christian) generations as quarries. The Giza pyramids were finished of in gleaming white limestone it was entirely stripped off.

The Temple of Artemis at the ancient city of Ephesus, had much of it's marble cladding removed and used in Churches.

People providing information that could be taken as medical advice (even if not so intended), should have medical credentials and should state them in their post. Most legitimate experts will also understand that the whole context of a person’s clinical presentation has to be considered as the same symptom can occur for different reasons. An expert will usually not say, “this is the only correct answer.”

I cannot speak to the physiological aspects of this at all, but I can say that someone who is hyperventilating may need medical attention. Other commenters have also suggested that bag breathing can be dangerous in some circumstances.

PLEASE NOTE that if someone is having a panic attack and they are not hyperventilating, DO NOT give them a bag to breathe into as this will exacerbate their symptoms. Increased CO2 inhalation has been found to correlate with worsened symptoms in individuals experiencing acute anxiety. CO2 enriched air will actually cause anxiety in otherwise healthy people, and is sometimes used in research studies for the purpose of inducing anxiety.

To be clear: I am not saying that someone who is having a panic attack and is hyperventilating can be given a bag to breath into. I can only comment on the often mistaken assumption that bag breathing is the appropriate treatment for a panic attack. Again, please always refer to medical professionals.

Way WAAAAAY less than 10%

1/10 people living in developed world today aren't farmers. Not even 1 percent. I dont know the exact percentage but its within a fraction of a fraction of a percent, for modern developed countries at least.

It's important to note that the Parthenon didn't degrade slowly over time, and crumbled out of neglect. It was actively blown up. OK it might have been already degraded when it was blown up, but it was still a structure intact enough to store munitions. Then the Venetians lobbed a bomb that ignited the munitions and Kaboom... no more Parthenon.

Today it's parts are being cataloged and when possible, reassembled. SOME of the parts are in museums around the world, so to fully reassemble the parts would require taking them out of museums and placing them back into unprotected open air... an untenable idea for museums, or would require manufacturing new replica parts, which has been done in a few cases.
