Fun fiddle-faddle Friday

It's almost midnight so technically I'm on time with this fiddle-faddle, lol! My question this week comes from when I went to Body World. Remember, to make it more fun, try to guess what the answer is instead of looking it up with Google. I didn't make this one multiple choice, but the question itself should help you. Whoever wins gets a special post from me! Good luck. :)

Q: The human brain needs 20% of our blood supply, but is only what percent of our total body weight?

6% I don't know really, that's a number that has been coming up a lot lately!
