I don't know how, but this works. DON'T scroll down too fast -- do it slowly, and follow the instructions below exactly, and do the math in your head as fast as you can. It worked on me. FOLLOW these instructions one at a time and as QUICKLY as you can! Then follow the instructions afterwards, ok? Answer as QUICKLY as possible but don't advance until you've done each of them!!! What is: 2+2? 4+4? 8+8? 16+16? Quick! Pick a number between 12 and 5. Got it? Now scroll down... The number you picked was 7 right? Isn't that weird???
