Thus far it seems to be a bit of a dud - watched for a while and only caught a single meteor. Maybe next year!

Interesting! Did not know this… I wonder if there are other languages that use a similar term.

"Blood poverty" was not a commonly used construct, but "Poverty of the blood" was used as a synonym for anemia in late 19th/early 20th century - especially from iron deficiency in young women, more frequently termed "chlorosis". See for example this 1892 paper, and a 1909 book by a McGill physician.

Wow - Is that your home freezer or the grocery store?!

The £100K treatment and £200K per year maintenance figures are for phlebotomy of 50 people rather than just one.
There are data that phlebotomy or plasmapheresis decreases PFAS levels.
Not saying this is the right approach, just that it is not the same as Bryan Johnson’s young blood nonsense.

It’s interesting when we think about how much being iron deficient or anemic impairs function & health outcomes. But in 1900, the top causes of death in the US were pneumonia & influenza, TB, and GI infections a so human history is a long battle against the microbes and prob any little edge mattered

Another factor may be iron-avid microorganisms that have been common causes of death historically (and still today in some places): E. coli, Yersinia, Salmonella, etc. Similar to hepcidin-driven iron sequestration, absolute iron deficiency can have a protective effect against growth of pathogens.

Eek! In a chair?! That would be like attempting a digital rectal exam without asking the patient to undress: uncomfortable & uninformative.
Alas, the physical exam is becoming a lost art - but hopefully since these were MPN clinical trialists they’d be better than average at spleen examination.
