Just wanted to say that there are OTHER places you lose hair when you undergo chemotherapy other than your head — I have no eyelashes or arm hair. Leg hair has been reduced, but it put up a helluva fight.
And the unmentionables have hair in some places but not others. It makes no sense to me.
I’d say it’s blood flow but there’s not that much flow in your eyelids, is there?
This is why I don’t like biology.
@feloneouscat Agreed. Biology sucks in so many ways... although FWIW I'm pretty sure the eyelids actually receive a lot of blood flow per unit volume of tissue.
I mean, why don't we have the ability to actually regenerate tissue, rather than just producing connective (scar) tissue to bridge the gap - and why on Earth can't we regrow gum tissue?
IMHO biology provides the strongest evidence against intelligent design... whether we were designed or not, it definitely wasn't done intelligently 🙃
Partner decades ago told me the number of stages a white cell goes through (don’t quote me on this — it may have been red blood cell or I’m totally making shit up because old) and that’s when I realized what a hack job we are (well, The Pandas Thumb was first, but this was the clincher).
@feloneouscat Probably white cells, that's a huge can of worms because there are a ton of different types, and their behaviour is extremely complex.
Adaptive immunity is absolutely nuts.
I still like innate immunity more, though - not least because the complement system, and specifically the membrane attack complex, is suuuuper cool. It's an extracellular self-assembling nano-weapon...
