Put it this way, tho typing a little slower would allow me to better spell words, you still got the information that I put forward. Why in that situation should I improve if I would just be accomplishing the same task but slower? Edit: in that case, is it even an improvement?

I’ve personally seen surprising improvement using the opposite approach - the addition of a low grade antibiotic (doxycycline) course. It’s been the only change to her treatment in the last several years. It’s astounding to see someone with relapsing remitting MS go from barely able to lift her hand to feed herself to almost standing on her own and doing a couple laps around the living room with a walker.

Edit: to add this is obviously an n of 1 anecdote, but it gives me an insight to investigate further.

Wait, what? Wouldn't they be subject to 0 gees, seeing as they're in orbit, i.e. experiencing no acceleration?

No. Black holes have a size. A black hole with 30 billion solar masses has a radius of a little less than 600 AU (Astronomical Units, the average distance from the earth to the sun).

More open carry laws, must issue laws, concealed carry laws etc

all of which support more people carrying firearms in public, concealed or openly.

Indeed, usually driven by fearmongering, scaremongering, propaganda and misinformation from right-wing politicians and corporate media like Fox etc

Cinnamaldehyde, thymol, citrus, chamomile, roman oil, carvacrol, oregano oil, green tea extract, saturated lauric acid and unsaturated linoleic acid appear to be effective.

If you pre-carbonate the concrete you are not going to have the alkaline environment which prevents the corrosion of the steel reinforcement in the concrete. That will necessarily lead to expansive corrosion and spalling of the concrete. An approach like this might be effective for mass concrete, with no reinforcement, but that's a very small part of the concrete market.
