I worry about "stuff that forces you to lie." Like airlines ask you "do you have a cold, cough, tiredness, itchy nose, sniffles or your foot hurts?" And if you have sniffles your choices are to tell the truth, miss your flight and lose $600, or lie. That's bad incentives.

Something I've wondered about: why do airplanes care about weighing your carryons, instead of your body weight + carryons? Why is a 95kg person + 5kg carryon fine, but a 60kg person + 40kg carryon gets a heavy penalty?

PSA: if you marry someone and you both love each other deeply, and your strengths and weaknesses are complementary, then it's totally normal to never have arguments. "Having arguments is normal and never having arguments is bad repression" is insane normie cope

Honestly I don't care about CO2 climate change any more. Easily solved with current technology. Care more about air pollution, heavy metals, microplastics, etc. It's annoying that climate change took over environmentalism

I sometimes think about Japanese excellence. For example, Japanese whisky is much better than the original, but Japanese coffee is very bad. Similarly, Japanese jazz is superior to American jazz, but Japanese pop music is garbage. What causes these big differences?

If you're not prepared for it, the cognitive decline due to aging can be a shock. For example, at my age I can no longer quickly multiply two digit numbers in my head, or consider a hypothetical scenario where I didn't eat breakfast

This came up because our kids asked about it. It's really tough to explain "lying is ok in this instance because both parties know"..

Thought about how school knowledge is still relevant to adults. Physics might seem like useless abstract knowledge, but it has many real-world applications.

The "physics" in this post is gibberish. Lateral g-forces are not directly related to angular momentum. They only depend on the speed and turning radius of the car. This type of path is known as a racing line. This orange line is a bad example. It also disregards traffic. en.m.wikipedia.org/wiki/Angular_m… en.m.wikipedia.org/wiki/Racing_li…

Women in their early 20s are incredibly annoying and immature. So any man who is willing to date them is either incredibly annoying and immature themselves (early 20s men), or extremely horny or abusive (older men). That's why people think older men dating younger women are weird
