Women automatically lose blood through menstruation.Maybe. The claim is that humans had parasites in the past so that excess iron was created by the body in order to take that into account, and that, therefore, our parasite-free modern bodies need to lose blood every now and then in order to reduce iron amounts to healthy levels. I suspect, though, that this is just a con made up by hospitals in order to get people to donate blood. Then again, Aajonus claims that menstruation allows women to live longer....
I've read that some scientists think that losing blood via donation or other methods can extend a man's life, because of the health problems associated with excessive iron buildup.
