    Here's another one about iron stores varying with age: Association of age, sex, and race with body iron stores in adults: Analysis of NHANES III data

    It has plots of mean serum ferritin versus age. On Fig 1, we that for men it reaches its peak quickly, at age 30-39. This supports Ray's claim in his Iron Danger's article. The amount almost triples from 17-19 to 30-39! However, for women it does not reach its peak before 60-69... Note that these are mean values but the individual differences are really huge.

    I don't imagine people reducing iron intake at they age, so for my this supports the second hypothesis, that higher ferritin is a disadvantage. The study questions notes the huge increase of store compared to childhood is not necessarily a good thing:
