Most of them. I've realized that I give up my hobbies after a while because what I want is to learn the topic, not do the thing. And once something has become second nature I'm no longer driven to pursue it. BUT I also have to have a goal/project for that new knowledge or I won't be motivated to learn... because video games are fun and the internet is distracting.

Electrical engineering. I feel like I have a nack for it but I went and became a biologist

Why I'm not "normal".

I don't understand popular culture. Things like "The Bachelor" and why people choose to spend their time watching this stuff on a regular basis for decades. I like sports but the fanaticism can be obscene (says the guy from Philly). I understand TikTok releases dopamine but how do people not realize they're addicted to these things? How is it that so many people are so gullible and unable to discern obviously fake or subjective or biased information. How do people fall for advertising? How are people not curious to know the reality of a situation? How can people defend things that are so obviously wrong or bad for all humans? Why is "obvious" obvious to some and entirely vailed and twisted for others?

There's something that a lot of people share that I don't understand. Something about the need to be right. The need to be protective. While also having the need to not care too much about anything more than entertainment. There's a subconscious desire to be part of something, to be a cog in the machine, to be a consumer, and to be lead by someone else.

I vividly remember, at eight years old, going to catholic catechism class and realizing that every religion claims to be the true religion and if that were the case it's plausible my religion was the wrong religion or that all religion was simply made up. I'm by no definition a very intelligent person so why is it that I can figure this out, before I barely even know what sex is, while the vast majority of human civilization for the past 2000+ years hasn't asked this question? How are we still warring over verifiably made up stories (the Bible's Jesus was a story based on several preexisting religions)?

I certainly have strong, sometimes less-informed opinions, but I'm here to learn. I like to think I'm humble but sometimes I let semantics get in the way. If you prove me wrong or offer something I hadn't considered, I'll at least shut my mouth about it and do more research.

To make it less about me, I want to learn more about whatever the subject is that I've just described.

Edit: This is funny and kind of relevant. Someone else recently posted a question on Lemmy about using the Internet Archive. This lead me to go back and look at a personal blog I had starting in 2005. This quote from 2006 is relevant to not understanding why people do what they do:

Look, I understand that Chain Mail will never go away, and it’s not even the hassle of hitting the little delete button. It’s just that I am so irritated by the people who think that they are either going to find themselves falling in love with the person they have in mind when they hit the send button or that they will be financialy independant because they SENT-AN-EMAIL. Do you idiot’s have any clue at all?! COME ON!!!!

Physics. Got put in a Physics class in HS after getting kicked out of public schools and had to transfer to a catholic school with advanced curriculum. Fuck everything was so interesting to me. WHAT THE FUCK IS IN THE SPACE THAT MUST EXIST BETWEEN ATOMS?! WHAT?! You can never measure the exact location of an object?!?! WHAT WHAT?!? Even if you could if you're observing it passively, it alters the results?!?! WHATWHATWHAT?!? No matter how random an occurancw may seem it can still be a patterned algorithm?!? Fuck me they couldn't teach their way out of a sex Ed paper bag but they sure as shit taught the fuck out of Physics

Quantum physics. But I'm at a stage where I actually would have to really start learning. YouTube videos don't cut it anymore. I would have to actually understand the maths and my brain can't handle that at the moment.

Geologic time.

I'd like to learn Spanish. My wife giggles uncontrollably at my Tagalog accent, so I kinda gave up on that one.

cognition, learning and bias.

anything related to the saying "you can't teach an old dog new tricks"

also retention on how well you keep what you learned.

TIME :deeper meaning of it. it's the concept even cracked a bit more could lead to multiple advances , it's fantastic dimension but unfortunately we are almost at limit it seems in terms of research.

Nothing really. I've had too much education. I'm ready to step away from it and just live.

Interspecies communication.

Sex. Yeah i know it sounds shallow. But for some people is not a possibility to experience it.
