You guys probably know about this already but if not, scientists have stitched together the circulatory systems of young mice to old ones - and also ones in which they have induced alzheimers - and found that it has a rejuvenating effect on the old/diseased mice by measures of physical and cognitive performance. I think there are at least several recent studies on this and i assume it's the inspiration for "blood boys" and the california company(ies) that sell blood transfusions.

Tfw the rich are no longer only figurative vampires. Happy spooktober. 💀
