Sacred rocks
This is really insensitive of me, and it's probably racist or elitist or ignorant:  I'm really not swayed by people claiming some area or rock is culturally significant to them and as such, other people shouldn't be allowed to go there or look at it.  The latest example is Uluru in Australia.  Before that, it was Mauna Kea in Hawaii.  This rock was important to your ancestors?  So?  It's a rock.  It was there before you decided it was culturally significant.  It was probably there before human beings existed, and it'll likely be there well after our species goes extinct. #sociology

Alcohol proof
The fact that there's a word that simply means "two times" another word is completely ridiculous.  "What proof is this?"  86.  "Ah, 43% alcohol.  Nice."

Contrarian followers
I'll never understand people who follow people and groups on social media just to be argumentative and contrarian with every single post and idea that the author presents.  Like, you're from team A, why are you wasting your time with team B?

It's 2009, I'm in my blue "Hope & Change" hat, driving my zero-emission vehicle to the nearby stadium for an Obama rally, where we'll chant things like "Socialized medicine!" and "Save the environment!" while we gleefully sing Obama's praises and curse his political opponents.  Nothing weird about that.  Nope. #politics

On life
"The celebrated Parisian doctor Professor Xavier Bichat developed a fully materialist theory of the human body and mind in his lectures Physiological Researches on Life and Death, translated into English in 1816. Bichat defined life bleakly as 'the sum of the functions by which death is resisted'." - Richard Holmes, The Age of Wonder

On learning
I think pretty much anyone can learn pretty much anything.  I don't think people are born to be good at math or science or art.  Most skills can be learned by most people.  But a lot of it depends on things like nature, nurture, personal interests, role models, geography, economics, politics, school systems, teachers, and personal learning style.  Most people can learn most things, but do they want to?  Did they live in an area with a decent school system?  Did their family and friends value education?  There are a lot of variables at play. 

Another thing I've noticed is that learning usually involves a combination of desire, ability, and speed.  I had a friend in school who had the desire and the ability, but not the speed.  He tended to score poorly on tests because he couldn't finish on time.  I had another friend who had the ability and the speed, but not the desire.  Neither friend pursued or succeeded in much education after high school. #education

I didn't want to be doing it, I didn't enjoy it at the time, and I wouldn't want to do it again:  My quarantine childcare experience

I think it's ok to look back at your past self and realize you were an idiot.
