    Because the tire is topographically a radially flattened torus, when you turn it half inside out, it becomes a 2D möbius strip. At this point it effectively has only one side. When you push such construct horizontally against a solid, because the z-axis perpendicular to the strip has no negative values (it only has one side), if that coincides with the orientation of the ∇Np of the solid, the z vector wraps around the solid. When the tire snaps to its rest state (inside in), it’s easy to see why it ends up around the pillar.

    This 3D animation demonstrates the concept:

    …or to a diabetic person whose health plan does not cover all the insulin cost they need.

    I should have specified that I was referring to superfluous stuff.

    For basic needs like education and health, any cost is too expensive. That should be sponsored by the whole society and government, and be free.

    In some cases, they are. My bachelor’s degree (5 years Engineering) costed me zero (in monetary units). Even the printed material was free, from the uni printhouse.

    We also have the largest free universal health care system in the world, and it’s even pretty decent in some regions of the country (Brazil).

    I’ve never used them.

    If I like an app or site, but the ads are annoying me, I do one of these:

    • If there’s an option to pay the creator/aggregator to eliminate the ads, and the cost/benefit is worth it, I’ll pay.

    • If there is no option to pay, but the app/content is worth the ads annoyance, I’ll keep using the app/site and watch/skip/ignore the ads.

    • If there is no option to pay, or there is, but the price is higher than what I perceive as the app/content value, I’ll stop using the app/site.

    For example, I paid for Baconreader Premium, but I watch YouTube ads, and I removed several sites from my google home page feed because they had more ads than content.

    I’m also stop using Reddit, as I don’t think it’s worth enduring their obnoxious native app.

    And no, I don’t use pirated software, nor watch or listen to pirated movies or music. If something is priced above what I consider it’s worth, I just don’t use it.

    Yes, Baconreader Premium could be consider as a “reddit ad blocker”, but it operated within Reddit’s approval. Now Reddit changed their rules, and it’s their rules.

    You answered “trying” as something that “is ALWAYS worth it” - which was OP’s question.

    If you now say you need to “weigh the pros and cons” - which I agree - then trying it’s not ALWAYS worth it, no?

    Then as someone else commented, each person has their own risk tolerance, so once each person weigh the pros and cons, trying will be worth it for some and not for others.

    So answering “trying” to “what’s something that’s always worth it” is rather paradoxical, as what you probably meant then was “trying it, but only when it’s worth it”.

    It was not the most important thing for me, but I agree: 15-20 years ago, veg options (and sugarless too btw) sucked. You really had to be committed to the cause to endure them.

    We’re not vegetarians, but my daughter has allergy to eggs and milk. We buy cakes, pies, brownies, cookies, etc from a vegan bakery that honestly are delicious - better than most non-vegan equivalents. We all end up eating them, although only she actually “needs” them.

    If vegan activists worked more towards kindly creating and showing the world vegan options that are as good as/better than their animal counterparts, it would help their cause MUCH more than pestering people, destroying property and making everyone hate them.
