High RBC is said to thicken blood and the heart has to work harder, although people who live at higher elevations don't seem to have that problem. High iron levels can cause the arteries to oxidize more which can cause stiffening and aging leading to greater chance of blockages So I give about 3 times year to stay in the mid rrange.
