No, but I tend to disable a bunch of the categories. If it makes it hard to avoid BS/irrelevant/uninteresting/"fake" notifications, notification perms go away, or the whole app does, usually with a free one-star rating. (As if that realistically matters)
Not really. Depending on how it works, it can slow down the browser itself due to needing to inspect and change content. Simple URL filters will, if anything, speed it up by blocking you from even trying to download unnecessary or malicious stuff.
Video games can get pretty finicky when you go off the beaten path, requiring a lot of extra "mechanical skill" to get right.
A certain glitch on a game I play involves carefully timed button presses while keeping the control stick in a specific, narrow range just outside the "deadzone". You then go fast, and backwards, and have to steer by switching which side you're holding the control stick on. If at any point you go out of that range (either through the center/deadzone or tilted too far), it instantly stops working. And some other tricks in that game are hard.
So that sounds like a good way to practice some dexterity, I know it's helped mine.
Other than that there's stuff like Rubik's cubes, arts and crafts,
Mine were a bit less acute than most cases here. It doesn't rank up to the kind of emotional trauma other people ITT have been through (though I'm not a complete stranger to that, either) but mine was when I realized my health is going to prevent me from ever doing what I want to and getting my shot at a reasonably happy life.
The slow dread of realizing decades of miserable, exhausting, bitter, mostly hopeless, unappreciated effort is void, and has been a complete waste - realizing that things "working out" is not really on the table anymore, and neither's anything else, much: all you can do is keep existing. That is easily #1.
Or realizing friends and family didn't have my back the way I thought and might actually join my list of a zillion problems. That was pretty scary.
Distant third, near misses in traffic - but frankly, I've had a stronger reaction from losing my fucking house keys. Almost got hit by a tram. Meh. Would've lost my appointment, I'm sure. Some shitheel trash in a BMW (because of course it was) tried scaring me by pretending to hit me while out for a walk, I'm like "😐 ... yeah? Make my day - in fact, throw it in reverse and get a proper run-up, you little bitch".
People, particularly people with controversial or "edgy" opinions, and especially people with JP-style controversial edginess, tend to hide their opinions behind that exact thing. His fanbase tends to be pretty religious about it and so people who start prattling on about his stuff come off as a red flag. It's a bit like "I'm not racist or anything, but-": you sorta know what's coming.
It's knee-jerk stereotyping, but not exclusively for a poor reason: it's a consequence of a bunch of his fans being cagey. You can obviously quote him or know some quotes without agreeing, but maybe it helps to make it clear. Or just don't refer much to him at all, I guess: anyone who doesn't already know about him can't really profit from learning about his BS.
