Honestly, I think Yahoo! Answers is causing it to get smaller.
Mine is very small.
2817CCs
I got me wonderful sub-orbital ridges
Big fat frontal lobe too
I give Mind-Gasms
It's the size of an engine block and weighs roughly 1,500 pounds.
huh uh normal i size i guess.
I'd like to think that its a normal brain size
Its just that i only manage to use 5% of it =(
Pretty big.
But it's hollow.
Oh well.
I have a 5 head (ya know a high forehead) so i would think mine was pretty big...
