A shallow angle from the sun give you that long shadow, but it also gives the light lots of extra air to pass through sideways on it’s way down out of space. The extra air filters out more light, and without an intense enough light your skin won’t make Vitamin D.
More of a “only speak in cultural memes” thing. We all speak in phrases mostly.
“I am feeling alarm at the moment of realization that every warrior I am commanding may be killed by the enemy who has prepared for our assault with deadly guile.” This complex and specific meaning might be encoded as “Ackbar above Endor when the Death Star struggled.”
The whole thing is a bit queationable with the whole “how can they say things without some sort of language independant of their cultural memes to encode those memes within.” That part never made sense to me.
