ermmm... I see 14.
There should be 11 faces on this picture. Average people see 4-6, sensible 8-10. The best see all 11, schizophrenics and paranoics 12 and more. And you? (don't take this one too seriously, I have even heard that there are 13 faces)
In this riddle i see 12 :S should i be worried???
Should i see a doctor?
