Give blood!

On Tuesday I donated two units of red blood cells, which is always entertaining. They remove a pint of blood, separate out the blood cells, and then return the plasma, which is mixed with a room-temperature saline solution. Brr! And then they repeat the process one more time.

Donating blood does wipe a person out, but it is a great thing to do. I would ask everyone who is capable to donate as frequently as possible. There are lives at stake, and every bit helps.
