There are three general reasons for establishing buffer zones: to provide sanctuary, to provide a neutral area that allows for supervision where contending claims exist (in order to, potentially, facilitate cooperation), and to simply reduce tensions through separation of disputants.
Iron and immunity are closely linked: firstly by the fact that many of the genes/proteins involved in iron homoeostasis play a vital role in controlling iron fluxes such that bacteria are prevented from utilising iron for growth; secondly, cells of the innate immune system, monocytes, macrophages, microglia and lymphocytes, are able to combat bacterial insults by carefully controlling their iron fluxes, which are mediated by hepcidin and ferroportin.

Reducing iron uptake can be done by avoiding vitamin-C and highly acidic foods consumed at the same time as foods rich in iron.If the blood iron levels are too high the body will try to dispose of the excess iron by dumping the iron into the tissues. If you have saturated your body with excess iron for years I think that the ferritin levels are unreliable for determining if you need to give blood.
