Does our body register pains in different ways? Well yes and no. We long thought no, but in a way we do. Hot and cold are same signals but faster and slower, and pinching is again another rhythm. We have mostly one type of pain receptor but recently it seems like we have some others after all.

Painkillers work in various ways so it's hard to answer your question. There's many painkillers and many answers. A paracetamol has a completely different working mechanism than morphine.

More thermometer space, plane and simple, they need to take advantage of the PS5 which allows for better memory, fidelity, performance, most games I play don’t have too much replayability despite being fantastic in their many regards. An open world game can focus on driving physics for example but has to give a pass on open worlds details or dynamics which could easily be enabled if there was more space to allow for these components and details

Exactly! Sound does travel through the vacuum of space, just not at a high enough frequency for human hearing to perceive. The frequency is very low; so low that it might be hard to describe it as sound at all. And sound travels very slowly in space, slower than a typical walking pace.

I get what you’re asking and have the same question.

My current guess is that, while sugar does dissolve in water, it leaves a residue behind when dumping the water. So to clean it, you would need to use a soap.

No clue if that’s even close, though.

I wouldn't use sugar because anybody who has smelled a used/dirty "water pipe" knows that bacteria already have a home there and I wouldn't want them having any more food than they already do, salt on the other hand is slightly anti-bacterial/viral/fungal and as such a really great substance for cleaning.
