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. The most popular seem to be lighthearted clever little truths, hidden in daily life.

Here are some examples to inspire your own showerthoughts:

Rules

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. No politics
    • If your topic is in a grey area, please phrase it to emphasize the fascinating aspects, not the dramatic aspects. You can do this by avoiding overly politicized terms such as "capitalism" and "communism". If you must make comparisons, you can say something is different without saying something is better/worse.
    • A good place for politics is c/politicaldiscussion
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct and the TOS

If you made it this far, showerthoughts is accepting new mods. This community is generally tame so its not a lot of work, but having a few more mods would help reports get addressed a little sooner.

Whats it like to be a mod? Reports just show up as messages in your Lemmy inbox, and if a different mod has already addressed the report, the message goes away and you never worry about it.

When you smell something, that thing is actually inside you. You can say you smell a flower, but what you're really smelling is some volatile molecules from the flower, and when you smell them they're already inside your nose.

Likewise, when you hear, the sound waves must have already entered your ear.

Even when you see, what you really perceive is light hitting your retina, which is inside your eye.

But when you touch something, that thing is still outside of you. Technically, can also be said of taste if you lick something, but then there's a strong likelyhood of some molecules of the thing entering your mouth as a result.

My sense of smell is terrible so it’s the least intrusive for me and my sense of touch is practically overwhelming on a regular basis so I’m going to say this has a lot to do with the type of body you live in

[–] HubertManne@piefed.social 3 points 4 hours ago

Oh. touch can be inside you.

You think your mouth is on the inside? Bad news, you're just a donut. That mouth is outside your body.

[–] FiskFisk33@startrek.website 7 points 19 hours ago

I'm not a donut, I'm a coffee cup!

Indeed Internet stranger, two things can never be true at the same time. /s

[–] surewhynotlem@lemmy.world 5 points 19 hours ago (2 children)

You're saying that things can be both inside and outside at the same time? Topologists hate this one trick.

I have a Klein bottle which says.. nothing, it's a piece of glass, but it demonstrates inside and outside not being so different after all.

More than one perspective exists, I know it's crazy.

TrickDacy

No, I meant they hate you specifically. It's completely unjustified, but topologists are jerks. They wouldn't go into details, but they blame you for 'The Incident'.

[–] TrickDacy@lemmy.world 1 points 14 hours ago

Ha, sure. People get really caught up in "universal" truths.

[–] CannonFodder@lemmy.world 9 points 20 hours ago (1 children)

Hmmm no. Sound is pressure waves, not actual matter transference. Light, is sort of the same (ok, that's a bit more complicated, but if we're going to get into the quantum mechanics of it, touch is just based on waves of probability too).
Conversely when you touch, there are lots of molecules that rub off and transfer. Some of those will embed into your skin.

[–] SuperPengato@scribe.disroot.org 2 points 19 hours ago

True, but the pressure wave is what is being perceived when hearing, light is what is being perceived when seeing, I never said what was being perceived had to be matter. In the case of touch, some molecules may enter the skin, but that is not the cause of the sensation. Even if you imagine an perfectly hard, smooth and clean surface that sheds no molecule, you should still be able to feel of you touch it.

However, I thought about it after making this post, but there also is a small amount of kinetic energy entering you when you touch something, and that may be what triggers your nerve... So I guess even in the case of touch, it remains true that you can only perceive something that's inside of you.

It also can be most intrusive when engaged in sex.

[–] Diddlydee@feddit.uk 12 points 22 hours ago (2 children)

When you touch something it's nerves that make the perception possible, which are inside of you.

[–] SuperPengato@scribe.disroot.org 4 points 21 hours ago (1 children)

The nerves were already inside tho, they didn't enter.

[–] Diddlydee@feddit.uk 1 points 12 hours ago (1 children)

Like the retina in the example which set the rule.

[–] SuperPengato@scribe.disroot.org 2 points 2 hours ago

The Light is what is being perceived in that example. The point of mentioning that the retina is inside the eye is that it means light must be inside the eye too when it hits it.

Go touch a gympie gympie and then tell me how you're not actually in contact with something.

[–] SuperPengato@scribe.disroot.org 1 points 19 hours ago (1 children)

tell me how you're not actually in contact with something.

Not what's being argued here.

[–] webghost0101@sopuli.xyz 4 points 21 hours ago* (last edited 21 hours ago)

Taste is just just more sensitive touch and smell.

Prove me wrong!

[–] protist@retrofed.com 3 points 20 hours ago (1 children)

Fyi, "obstrusive" is not a word that exists. I think you were trying for "obtrusive" but actually needed the word "intrusive."

[–] frightful_hobgoblin@lemmy.ml 4 points 23 hours ago

touch is the sense that's most commonly bothering ya, creating discomfort
