A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. A showerthought should offer a unique perspective on an ordinary part of life.

Rules

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. Avoid politics
    • 3.1) NEW RULE as of 5 Nov 2024, trying it out
    • 3.2) Political posts often end up being circle jerks (not offering unique perspective) or enflaming (too much work for mods).
    • 3.3) Try c/politicaldiscussion, volunteer as a mod here, or start your own community.
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct

I just realized how incredible it is that we don't have toes growing out of our ears. (lemmy.world)

AFAIK it all boils down to the fact that during embryonal development our cells, which at that point were just a blob of undifferentiated autonomous chemical machines, somehow managed to unanimously agree upon the cardinal directions (up-down, left-right, front-back) for future development - and thanks to this, we don't have toes growing out of our ears.

This is just based on an offhand comment from a lecturer during a practical session during my time studying animal management in college, not directly from a biology lecturer so citation needed, but apparently rabbits don't have a combined windpipe/digestive tract and it means that a blocked nose can kill them. So even if choking wasn't a thing we'd have to worry about something blocking our noses and suffocating us.

Oh that's actually a good point, so there are upsides as well.

Movies would also look really silly when someone would get killed by having their nose pinched closed
