How much blood can you lose at one time without dying?

Pints, please, or I'll have to go find my unit converter. Also, in seriousness, can anyone say what blood tastes like?

According to a retired Los Angeles County sheriff's lieutenant, an expert in crime scene analysis and police procedures, during a crime analysis:



"A healthy person, Clark told jurors, walks around with a total blood volume of roughly 12 pints."

"But for death to occur, he said, a person would have to lose about 4 pints, or two of the same IV bags, worth of blood."
