I went to donate blood today but they turned me away.

Everyone's here like having too much iron in their blood and I'm here having to take care that my iron level's high enough - curse you, mature female body, cuuuurse you!

Funnily enough, having too much iron in your body is more of a problem for females of Irish descent (or to be more specific, having too much iron causes more problems, not that it's more common for them to have more iron).  Not as much of a problem for males according to studies, but it could still be.
