There are cognitive risks to the anesthesia used in surgery, especially in the elderly, for conditions such as postoperative cognitive dysfunction (POCD).

If you want your teeth to be where they are, absolutely not. You signed up for a life of retainers

Just one point: Soil is actually of biogenic origin. That means you won't find it anywhere where there's no life to create it. The thing on the surface of terrestrial planets in our Solar system and most moons is properly called regolith.

There’s no conclusive sum of factors though a big one is the Amygdala overactivation (and, if relevant, it’s growth in comparison to other parts during the onset of symptoms) causing difficulties with encoding, storing, and causing behaviors that worsen recall (and whatever affects recall is usually actively affecting the other two components of memory as well). The Amygdala in this situation, in comparison to the sick brain, is what is causing the memory defecit- as opposed to a random assortment of possibly damaged neurological components, that could include the amygdala (which is to say being sick can make neurons, parts of the frontal lobe, the back area of the brain responsible for vision, or all of them become damaged in some way, for example) and while the effects may be the same, PTSD may have been a risk factor for or an effect of receiving the brain injuries associated with a virus more times than not

Just to further elaborate, PTSD is a mental illness (though it’s common coupling with brain injuries is something if interest), whilst memory degradation from viruses, specifically from COVID, seems to be from either inappropriate immune system activation or neurological (like described above)/systemic damage (think possible gut biome or other body damage that may make it harder for you to do anything that was easier pre-COVID, like joint aches for example)

(for those reading whom are struggling with PTSD, please remember that it is a normal reaction to abnormal circumstances)

Covid brain fog was wild. Never experienced something like that before. I didn’t get very sick at all, extremely mild. But my brain was just mush. Forgetting if I’d done everyday tasks, re-doing things I had already done.

I remember learning about a fungus in my mycology class that basically, as part of its reproduction, would absolutely BLAST some seed in the air. Basically 0 mass so it's nothing people would notice, but the speed was staggering. Grew on horseshit I believe, don't remember the name tho..

EDIT: it wasn't the speed that was staggering, but the acceleration of the spore. From Wikipedia in the comments: For a sporangiophore less than 1cm tall, this involves acceleration from 0 to 20 km/h in only 2 µs, subjecting it to over 20,000 G, equivalent to a human being launched at 100 times the speed of sound.

>An object traveling faster than the speed of light is going backwards in time in some frames

Where are you taking this information from? This "follows" from special relativity, where massive objects travel at strictly less than c.

Such statement don't have any physical meaning. You're braking the assumptions that were used to derive the equations you're relying on.

Does this mean I can finally stop wearing my retainer after 15 years?

Once when i was sick, i recalled a really important phone number that i had forgotten some 6 months prior. i made sure to write it down then
