Modern building standards make it extremely likely a fire cannot pass between units (you can never realistically entirely remove it - people occassionally do things like hang sheets off balconies or store tanks of fuel etc). This is before we talk about how many fires are put out by fire brigades before they've fully destroyed a single unit.
Honestly - the risk of a fire in your own apartment is drastically higher than the risk of it being engulfed in a fire caused outside of it.
Although the video depicts tiny one-room apartments, the second market for this is people who'd like some extra space without the cost and inconvenience of extending their house or moving house.
i.e. if you're willing to pay $2000 to get space for a home office or exercise space, that'll get you a pretty fancy folding bed - but it's a fraction of the cost of an extra bedroom.
You don’t need something robotic but I expect folding beds (especially outside the most expensive cities) see a lot of use in guest bedrooms and similar. A traditional bed sort of locks a room into a guest bedroom function even if it’s rarely used as such. Better to have a sofa bed of some sort and use it for whatever purpose most of the time.
This has to do with mitochondrial metabolic processes being the most efficient to break down smaller quantities of sugar. There are mitochondrial mechanisms to break down a lot at once that are turned on in the presence of more sugar but they just aren’t as finely tuned and thus generate free radicals which can cause cellular problems. There really wasn’t a point throughout evolutionary history where there was a prolonged abundance of sugar available to the degree it is today. Because of that, the mechanisms to break down a lot of carbohydrates/sugars at the same time just did not evolve to be as operationally efficient. Free radicals can cause DNA/RNA disruptions and also damage other processes. Source: father is a dedicated microbiologist
Interesting to know about free radical creation when mitochondria are overwhelmed. I’m sure there’s a lot more factors involved in aging however, not the least of which would be senescent cells. Telomeres only allow cells to divide ~50 times before they’re unable to replicate further.
Before they start eating their own instructions. Every chromosome will become a Y chromosome some time in the future if we do not invent the necessary means.
Unfortunately free radical aging theories are not enough. It's a tiny piece of a picture, because effectively immortal organisms still use the same mechanisms.
And it's not for some magic scavenging either.
Even telomere bound is not enough.
It's likely a set of advanced repair and local homeostasis so that feels still execute the complex maturing program correctly.
Too many senescent or damaged cells might just break the conditions... And mitochondria and cells have excellent mechanisms of dealing with reactive species they make, but sometimes chemicals leak in.
I'd be more concerned with infections and resulting damage at this point, plus toxic damage.
Including endogenous like glycation.
Ask your father about drug induced mitochondrial dysfunction. I had ciprofloxacin 4 years ago and my exercise tolerance swiftly dropped in the months afterward. Research tells me this is due to mtdna depletion and dna damage and I just want to know how to get better. I now have stage 1 diastolic dysfunction and a plethora of seemingly unrelated problems, coming from none before.
It's probably not fixable if it's really that. Even if mtDNA is fine the mitochondria have their own mechanism for senescence based on other damage, just like cells.
It does not even have to be caused by radicals.
And would there be a way you think to test if that's really the case?
I have talked with some people who had like severe reactions to the drug who managed to get some kind of mitochondria testing and it would say stuff like "30% of the active sites are blocked on the mitochondria"
What is always strange is how everyone expects the default is this Not happening. People are often bored and nosy and if given the opportunity, they will spy on each other. All primates do this.
Here's what you aren’t seeing, if I may: Consumers see the end product. They intuit rules based on what they see. I only see pictures and videos sent to me, and then they are gone. From this their mental model becomes No one can see media that is not sent to them, and the media is gone after it has been seen. This is strikingly different from the way a developer at Snapchat models the world: We run a big warehouse full of data and media. We present this media to users based on logic that prevents arbitrary non-admin users from seeing others' content and from experiencing that content repeatedly. Oh, and we should eventually get around to writing that cronjob to delete old media. And once we rule the world, we can spend time playing with end-to-end encryption, maybe.
People aren’t stupid (mostly). They are just ignorant (in the literal sense). They are extrapolating in a way that makes sense in a physical world but not in the digital world.
The clearest analogy is that of actual dice vs. video gambling or the virtual spinner in a free-to-play game. With actual dice, what you see is what you get: fair odds. But that virtual wheel is 'weighted' to end on the worthless prize right after the jackpot space nearly every time.
