Over 92.1% of statistics are made up on the spot, including this one. You would think that in a modern society where science is supposedly replacing religion people would be a little more skeptical when random numbers are thrown around.
“You only use 10% of your brain”. You hear this everywhere, it seems to be accepted by everyone as fact, written in stone by God himself. I have even heard it repeated by doctors who should know better. It seems to be permanently lodged in the American psyche even though there is no evidence for it, and never has been. I am going to start asserting that we only use 18% of our sense of smell, if we could only use that other 82% man what a world that would be!
