For me, it may be that the toilet paper roll needs to have the open end away from the wall. I don’t want to reach under the roll to take a piece! That’s ludicrous!
That or my recent addiction to correcting people when they use “less” when they should use “fewer”
Theoretically no.
What is colour blindness if not one persons receptors (rods and cones) translating those waves differently than everyone else? Meaning that what light “looks like” to them is completely different.
literally everything, even matter itself, is just energy vibrating at different levels of the same scale. From sound, to light, to Gamma radiation; everything exists on the same spectrum, merely inhabiting different frequency spans. so in that respect there’s an argument to be had that nothing exists until its sensed by an observer.
But that’s delving into philosophy.
