What's the difference:giving blood an hour before/giving blood an hour after?

Whats the ****ing difference and what does it matter?!?! Is it really that much of a difference giving your blood an hour prior to the fight than giving your blood an hour after the fight?

This is ****ing ridiculous. I cried when I heard the news man. I'm so depressed right now.
