So I just went and donated blood again and durring the recovery period it occured to me that it takes quite a bit of work for your body to regenerate that lost blood volume and the actual blood cells. Regrowing that many cells seems like it would be fairly energetically intensive. So how many calories does producing all those new blood cells actually consume? Is there even a way to know that?
If you’re however old you are now and still not a blood making machine, I’d say see a doctor.
As a chronically anemic person, I need other people’s blood making machines.
Go donate if you can! I will take your sweet, sweet red blood cells.
I’m at nearly 50 donations (each 0.5L) of sweet sweet O+. Apparently, my blood is really good for children since I’ve never contracted some specific disease.
That would be CMV. Newborn babies and pregnant women and cancer kids need CMV-negative blood (if they need a blood transfusion). Thank you for donating.

I’m O+. We should be friends!
