Yes indeed! Most people have iron deficiency, which makes iron overload a very complicated thing to explain to people :-) But it does exist, and it is lethal, but good treatment and care does expand life expectancy dramatically, so that's a good thing. It is said that it is a deviation that got picked up and survived due to the vikings, who, due to this Iron Overload, were able to be at sea for really extended periods without becoming sick, since they had extra iron reserves...
