Here's a mind game. Just follow the instructions below:

DON'T scroll down too fast-do it slowly and follow the instructions
below exactly, do the maths in your head as fast as you can. It may help
to say the answers aloud quietly.

FOLLOW these instructions one at a time and as QUICKLY as you can!

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?

weird???

How about the following exercise. There's no trick or surprise. Just
follow these instructions, and answer the questions one at a time and as
quickly as you can!

Again, as quickly as you can but don't advance until you've done each of
them...really. Now, ARROW down (but not too fast, you might miss
something)...

What is:

1+5

2+4

3+3

4+2

5+1

Now repeat saying the number 6 to yourself as fast as you can for 15
seconds. Then scroll down.

QUICK!!! THINK OF A VEGETABLE! Then arrow down.

Keep going.

You're thinking of a carrot right?

If not, you're among the 2% of the population whose minds are warped
enough to think of something else. 98% of people will answer with carrot
when given this exercise.
