This is nonsense. It’s so the tear can be seen by other Fremen and the moisture salvaged.
Does that mean they are healthier too? Gotta make sure I get my daily protein
Did anyone look this up?

They do indeed have more protein. The conclusion that it’s for them to fall slower seems to be just a hypothesis
The explanation feels very much like a “just so” story to me, as much as I want to believe it.
I think this is why it’s helpful to think of it, not as a ‘why’, but as a ‘how’. There are tons of things about our bodies that do not make sense, but which hasn’t killed us enough to not spread. These can still have an effect on us, and that’s what’s interesting to me.
Trying to get a reason out of evolution can be useful sometimes, when we actually want to know what lead to a trait becoming common, but for most things, especially concerning humans, the ‘how’ is so much more interesting, because we can actually get concrete answers to that.
The Guardian, not a journal:
Not all tears are alike. The human body produces three kinds: basal, which form an oily layer over the eyeball to keep it from drying out; reflex, which appear when an eye is bothered by cutting onions or a speck of dust and needs to flush the irritant away; and psychogenic, which are shed for emotional reasons. Notably, emotional tears have a higher protein level than basal and reflex tears, which makes them thicker and causes them to fall more slowly.
This thickness intrigues me. The longer it takes for these tears to travel down a cheek, the greater the chance that they will be noticed by another person and their message perceived. Tears are a social signal.
The ancestral high-protein diet: drinking the tears of your fallen enemies.
It’s so my 2 foot long snaked tongue can slither over to your face and lap up those nutrients
