[This paper in Cell (pdf)](https://www.cell.com/cell/pdf/S0092-8674(22)01530-6.pdf) examines the role of endogenous retroviruses and senescence and was discussed in the latest podcast from "This Week in Virology."

During the podcast, they also discussed other research showing that, in mice, repeated blood transfusion from young mice to elderly mice over extended periods of time produced rejuvenating effects. Thinks like improved strength, thickening of cartilage, etc.

There is a very long way between that research and increased lifespan in humans, but my opinion is that it's worth considering the possibility we'll eventually get there. Or if not lifespan, per se, then better health through the lifespan (health span).

Exactly. I didn’t want to accuse OP of buying cheap tape, but proper electrical tape will be clearly labeled as electrical or electrician’s tape, will have the NEC standard on it, and costs $3-$5 a roll unless you’re buying in bulk.

And even then the minimum is 170 degrees. 3M and a couple other companies certify their vinyl tapes above that, but one that’s barely compliant could still get hot enough in a hot car for the glue to start to soften.

Can I draw attention to the amount of attention thrown at covid, too? When covid came around, the world screeched to a halt and opening up was slow and dangerous until we got a vaccine. Many workplaces, stores, restaurants and other businesses were having to close for weeks at a time because a strain of covid was spreading among their employees. Everyone wanted that vaccine really bad and the sooner the better. HIV, on the other hand, can be (mostly) avoided by practicing safer sex and not sharing needles. It’s much harder to spread and even if you have HIV, you can mostly live your life normally nowadays. There is much less emphasis put on getting an HIV vaccine.

(BCH Political science) I’m gonna try to give you a useful answer, but I will try to keep it simple and between the lines.

People often forget that culture and politics are incredibly close to each other regarding differences between countries. While western culture (English language, American culture) is more often focused on the democratic system due to the “discovery and rise” of it in Europe, it has certainly not picked up all over the world. While you can have Coca Cola in your country and have a large majority of people speaking English this isn’t often an example of a country that also handles liberal economics or democracy(western liberalism)

Chinese youth for example has had over the last years an obsession with American culture stuff (Wild West etc.) But liberal economics and western liberalism is far from being in China. So while a lot of European countries have taken up that democracy, liberal economics, American culturing, and speaking English it is certainly not an all in one package

Electric cars don’t have alternators.

In regular internal combustion engine cars, the alternator and the engine work to convert chemical energy from the fuel into potential electric energy for the auxiliary systems. Electric cars already have tons of this potential electric energy just sitting around in their battery arrays.

Because I can’t explain “the economy” in an Reddit post entirely I will do my best in a small example/explanation.

You can see this economy as this kind of circle with some smaller circles around it. We have all decided that we will live with a system that gives us a digital or physical piece of paper to pay with. The economy revolves around the value, sustainability and usefulness of that product (money). That is the main circle.

You could see that part of the start of the main circle is raw materials, like for example that of farmers, miners and loggers. Then we need some people to transform the raw material into something. Factory workers, builders who build a house or Cooks. Then we need people to buy the iPhone, buy or invest in the building and go out to eat. The thing is that everyone in that circle pretty much needs something from not only their own profession:( Money and Maybe a house) but also from the other professions, like an iPhone or food, this does of course include the farmer who grew the ingredients for the food or the miner who dug up the gold for the iPhone. So to put it simpel it is a circle build around the needs and demands, but also the money we have chosen to exchange products with

Does that answer it a bit ?

"Planet Earth" has shown a mother polar bear hibernating. She gave birth in her den, nourishing the little ones until they are big enough to follow and withstand the cold. She does not leave until then and is really famished. And you see her rolling around in the snow to clean herself.
