Live & learn. No, READ & learn. I just read an article about a veterinarian attempting to save a 28-year-old (the article said the species can live into their fifties) Andean condor bird through a blood transfusion. And guess what I learned?
Birds don’t have blood types!
Imagine that. Fighting cancer and damaging effects of chemotherapy would be SO MUCH EASIER for patients of all ages with rare blood types if that were also true of humans.
