>>154734353 paths to healthy blood:
1. cardio
2. not being a fatty
3. blood letting - if you arent a menstruating aged woman you should be bleeding some other way. your blood collects iron and has no way to remove it, they load it up in your bread too for waaaman because one size fits all!
for me, I hate needles and blood in general so leeches and mosquitoes are preferrably ways to remove old blood than a knife or needle
