@shredalert: It turns out I read that before, shared by someone on Math SE!
For all I know it was you hahaha..
@amWhy @user400188 @shredalert: If that Phil SE answer I mentioned above was on Math SE, all the logicians who see it would downvote it. But nobody on Phil SE seems to think it's wrong. Unsurprising but disappointing. Such answers slander mathematics.
Fun Fact: WA gets the Wrong Answer for "lim sin(floor(1/x^2+1))/sin(ceil(1/x^2)) as x to 0". It shows the correct interpretation of the expression, but gets the wrong answer. Evidence that this is due to hard-coding is because previously I tricked it with "lim sin(1/x^2)/sin(1/x^2) as x to 0" and posted about this somewhere, and they 'fixed' it but then I tricked it with "lim sin(1/x^2)/sin(1/x^2) as x to 0" and posted on Math SE about it, and they again tried Whack-A-Mistake.
Yeah; I'm hoping the issue is at least partly amenable with physical therapy; The first MRI showed a compression fracture in one of the vertebrae in my lower back, and a couple of bone spurs, but they want a closer look. I'm really limited in the amount of time I am able to stay standing, or sitting, so I'm sort of a "jack-in-the-box" as a result: up-down, up-downj
@shredalert I've struggled with the same off and on. When it's muscular, muscle relaxers can really help at it's worst. I had a chiropractor who shared with me the following exercises: Remember "Yes. No. Maybe. Chicken (turtle)." Slowly move your chin to your chest, and raise it (aka "nod yes slowly"). Slowly turn your head from side to side (slowly, displaying "no"). "Maybe" is slowly bringing you left ear close to your left shoulder, and right ear to right shoulder.
And "chicken" (some call it turtle) it's hard to describe.
@shredalert It's actually somewhat helpful; but I let it slack until I'm having a stiff neck, and try to start it up again. (Which takes a while to be helpful, whereas if I kept it up regularly, even just once per day, I'd probably be better off.)
