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.
But arm hair should be the same, right? My forearms have hair and I also have pit hair.
It’s like a free for all! IT’S ANARCHY!!!
@feloneouscat There has to be some field of study on why hair grows at different speeds. I'll probably end up looking it up next time I can't sleep. 😄
This does make me think my grandfather just didn't tell us what hair he was losing. He'd just shrug and say, "Been bald for years. There's nothin' to lose."
@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...
@feloneouscat I ended up learning about this when my niece was going through chemo. It's the rapidly growing cells that get weakened. Since you said the leg hair has reduced slower, that makes me think it grows slower. That really makes me wonder how fast eyelashes are growing!
