Rule 1: All post titles except for meta posts should be just plain "hmmm" and nothing else, no emotes, no capitalisation, no extending it to "hmmmm" etc.
I will introduce more rules later and when I finish doing that I will make an announcement post about that.
For overall temporary guide check out the rules here: https://www.reddit.com/r/hmmm/wiki/rules/
I won't be moving all of them here but I will keep most of them.

Are you implying that your fingernails were never cells of your body? How does that work?
Well I'll have to look it up now, but I see it as a substance produced by the body that isn't made of cells itself. Like any of the other excretions and things the body makes.
Edit: apparently both your nails and hair are mostly made of keratin, but keratin isn't produced and excreted to produce the nail and hair structures like a playdough factory like I imagined. Special cells are produced that are primarily keratin and they are added to like a chain and die/harden as they are pushed out from the body.
That is absolutely fascinating. I had the same assumption.
Damn, well that is interesting
