With in medical science there is speculation that having less iron is what helps women to live longer than men. Also, there may be too much iron added to modern foods?

"A study of nearly 3,000 middle-aged men found that those who regularly donated blood had 88% less risk of heart attack. Scientists have a few theories as to why this is. First, there’s the iron thing. Several studies have shown a connection between high iron levels and increased risk for cardiovascular diseases. One study found that high iron levels immediately constrict blood vessels and reduce blood flow in your circulatory system. When you have reduced blood flow in your arteries, they begin to harden. What’s more, high iron levels in the blood can oxidize cholesterol, and the product of this oxidation deposits itself on the walls of your arteries causing build up which can lead to heart attacks and strokes.

Besides reducing iron levels, donating blood on a regular basis also reduces blood viscosity, or thickness. Blood that’s too thick doesn’t transport nutrients to your tissues as well. Generally, men have more circulatory problems due to high blood viscosity than pre-menopausal women. Researchers theorize that a woman’s monthly period helps keep blood viscosity in check."
