Animals.

As a concept, they become less prominent in your mind as you age (exception being pets).

A 12 year old is clearly much more likely to be thinking about e.g. zebras, orca whales, tigers, etc. than a 30 year old.

Lesson in there.

I’m watching this North Face YouTube video, these ppl are skiing in Antarctica, bunch of penguins show up on the screen. I realize, man I haven’t really thought about penguins in a long time.

Pudgy Penguins don’t count because they don’t feel like penguins, they feel more like generic cartoon anthropomorphic characters.

Agreed. Bring back thinking about animals.
