Red Blood Cells

A story from Pop:

I was burning some junk mail in the fireplace yesterday. Aaron came by and wanted to keep the embers going so I suggested that he get the bellows to add oxygen to the fire. After pumping the bellows for a few minutes Aaron turned to me and said: "This is just like the way our bodies add oxygen to the red blood cells."
