Spill in in your backyard and it SOAKS IN to the dirt. Does no-one get that?
It all has to do with the amount of blood. I'm to lazy to get into any heavy math but an 8 year old boy's blood capacity would be around 1.5 to 2.0 litters. Unless someone collected the blood. Wasn't that in one of Aarons believable/unbelievable statements.
