These days, I take iron supplements. I used to live my life, and donate blood, without taking iron supplements, figuring that I was okay so long as my iron levels were high enough to let me donate, and that donating would assure that I did not suffer from hematochromatosis in my old age. However, my doctor was worried about my falling iron levels, so I started taking supplements, and that brought my blood iron levels back up.

Except on December 14, for some reason.
