Here is another illusion of a kinder and gentler approach:

1- Find the C below.. Please do not use any cursor help.

 OOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO
 OOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO
 OOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO
 OOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO
 OOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO
 OOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO
 OOOOOOOOOOOOOOOOOOOCOOOOOOOOOOO
 OOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO
 OOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO
 OOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO
 OOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO
 

2- If you already found the C, now find the 6 below.

 99999999999999999999999999999999999999999999999
 99999999999999999999999999999999999999999999999
 99999999999999999999999999999999999999999999999
 69999999999999999999999999999999999999999999999
 99999999999999999999999999999999999999999999999
 99999999999999999999999999999999999999999999999
 

3 - Now find the N below. It ' s a little more difficult.

 MMMMMMMMMMMMMMMMMMMMMMMMMMMMNMM
 MMMMMMMMMMMMMMMMMMMMMMMMMMMMMMM
 MMMMMMMMMMMMMMMMMMMMMMMMMMMMMMM
 MMMMMMMMMMMMMMMMMMMMMMMMMMMMMMM
 MMMMMMMMMMMMMMMMMMMMMMMMMMMMMMM
 

This is NOT a joke. If you were able to pass these 3 tests, you can cancel your annual visit to your neurologist.
Your brain is great and you ' re far from having a close relationship with Alzheimer. 
 

Congratulations!
