I'm not really a gamer, but I experienced something maybe similar with the ipad. When I first got one, of course, I was reading news and swiping away and it was completely natural.
Then I'd go to a restaurant and when reading the menu, I'd start swiping at the paper or vinyl menus like it was a tablet. It's a curious phenomena to have that brand new tablet gesture overtake decades of behaviors and perceptions with real paper.
Incidentally, I know of a few people, friends of my parents, that have gotten a shunt for NPH. They suffered from one of the 3 "W" symptoms of NPH, wet, wobbly, wackiness, that you're certainly aware of.
One had a dramatic improvement very quickly, where one or more of the Ws was resolved. Another had the spinal tap indicating she was a good candidate, but the shunt is still not resolving all the issues even after 2 months.
Do you have any clinical experience with the success rates of the shunt?
I can't help with tinnitus itself, but I highly recommend "Eargasm High-fidelity Ear plugs", or similar devices, to help prevent further damage.
They work really well to dampen loud sounds and, importantly, they let conversation through, though it sounds muffled. But you can feel the difference. They are much better than using foam ear plugs, which muffle everything.
I used to go to a lot of concerts without any ear protection, when I was young and dumb. I REALLY wish I had these things back then, since I've acquired mild tinnitus as a result.
Now I carry them on my keychain all the time and use them even in restaurants and bars or whenever I'm some place where I have to speak at an elevated level.
Well, crap. My mom complained about tendon damage issues after taking Cipro. I don't remember which tendons, probably legs, but I don't think she ever felt recovered from that. She probably only got generic warning statements that some people may experience side effects.
Anyway, antibiotics causing damage like this sounds like it could have triggered an auto-immune problem. If so, then that is a large quagmire.
We (or at least I) may base our estimates on the happy-path.
That is, I can see how to solve a problem in the common case. But as I code, I encounter the myriad of error cases, exceptions to the common problems, and especially the interactions of all these. Then add in performance considerations and the complexity can multiply quickly. The long-tail of those errors and exceptions can be very time-consuming to solve, so the mean is likely to be way off.
It's obviously much easier to estimate when you're experienced with a problem space. This should mean that you know how to solve a particular problem as well as the likely exceptions (non happy-path) you'll encounter.
If you're experienced with the domain, you can fit the relevant partial solutions in your head and more accurately judge what could go wrong with your code. But more generally I think this is similar to solving problems in other domains as well, such as architecture, building a car, or anything with many moving parts. These domains do not usually have loosely coupled sub systems.
I'll add my anecdata. I'm dark skinned and an engineer, so sunlight and me are strangers at best.
I've taken 5000 IU/day (with vitamin K2) and have my blood levels tested every year. I don't remember what my serum levels are but they were on the high end of healthy individuals. Last I checked, my levels matched what a person reaches who spends the day in the sunlight, perhaps like a outdoor worker.
Whatever you try, if you have an annual check up, you should get you blood levels tested to verify you reach sane levels. I think most studies and articles fail to mention how dark the subjects are.

I second this recommendation for Insight Timer. I just use it as a timer that’s nicely customized for meditation, though it has guided talks and recordings that others may find useful.
The timer is MUCH better than the built in iOS timer. It has pleasant (less jarring) bell/gong sounds and customizable presets.
It also keeps track of your sessions which is useful as a subtle nudge to keep a routine practice.
As another commenter noted, there's a general internet standard defined already for cryptographically timestamping and signing digital artifacts, like JARs, PDFs, dotNet assemblies, and many others.
Many large certificate issuing orgs run timestamping authority servers. Tools like Java jarsigner, Adobe Acrobat, and many other tools are designed to work with them. Search for "rfc3161".
Maybe it was in the Free Solo movie or other interviews, but I thought he said that his route during Free Solo was a difficulty level of about 7/10 for him. So he was comfortable enough that it was not the hardest climb for him; after a ton of practice on that route, with ropes, of course.
So to be statistical about it, the difficulty level for him was at the edge of 1 standard deviation of the mean of his capability. Maybe that's enough margin that he could detect when he's really in trouble.
I was always somewhat concerned about the abundance of critical raw materials for ARC or other fusion projects. I had assumed that the rare-earth elements in the REBCO tape, e.g. yttrium, would be constrained. I didn't suspect that beryllium could be a limiting resource. But I wonder if the lack of supply is related to true scarcity or just to a lack of a profitable market currently.
These are all questions I'd want to ask domain experts in mining and fusion.
But I agree that fission would be a better solution for baseload, at least for the next 10-20 years. If only newer modular designs were actually approved...
I added a link above to a good talk from Dennis Whyte. I think it will help address your question about the additional engineering issues in a commercial reactor based on ARC.
In short, from my basic understanding, there are quite a few additional major challenges involved with fusion power generation. e.g. After creating net-positive fusion, the heat must be efficiently extracted without stopping the reaction. Also tritium must be continually extracted from the FLiBe (fluorine-lithium-beryllium) bath that stops and collects neutrons and extracts the heat.
Since I'm a total novice in all this, I don't know if these require incremental innovations or major advances. But from the video, the problems mentioned seem to be more tractable than achieving fusion ignition or Q>10.
